Why are more and more customers choosing PCBA one-stop service?

More and more customers are asking if their suppliers can provide PCBA one-stop service. Many of them purchased these two types of circuit boards and components separately after discovering them.

Therefore, more and more customers are choosing Printed circuit board & electronic components one-stop procurement services for the following reasons.

Firstly, the sales channels for components are networked, and prices tend to be transparent.

At present, the entire component sales network is actually available. You can find any type of material by entering the online model, price, manufacturer's production status, and whether there is inventory. In fact, the entire process is very simple. If the company purchases on its own, it needs to ask someone who knows the materials if the component supplier is genuine and when it can be shipped. But in this way, the final purchased materials may have the same price as the supplier, which is equivalent to spending more money on the same thing.

Secondly, labor costs increase and own cost decrease to cope with uncertainty

Faced with the current unstable situation, we can indeed feel that orders are not actually increasing, but decreasing. It is absolutely impossible to reduce labor costs without increasing orders. The entire PCBA one-stop service includes the entire budget, with controllable prices and no other costs, reducing uncertainty.

Thirdly, delegate professional affairs to a more professional team for handling

Compared to General Solutions, it may not have much understanding of the current price trends of PCB boards and components, as well as new SMT technologies, as it does not involve specific backend production processes. But PCBA manufacturers have to handle these backend processes every day. The engineers at the PCBA processing plant are very clear about what type of board and solder paste to use in what industry.

The most important point is that PCBA manufacturers have many customers and there is also a high demand for parts procurement. Correspondingly, you can obtain more terminal channels, thereby obtaining more products, so the price will definitely be lower and the quality will definitely be guaranteed. After all, end distributors do not want to lose their main customers. If you purchase from one company, you may not be able to meet the lowest quotation from other companies.

Are you looking for a reliable one-stop PCB assembly services provider for the electronic product of you company?

Hitech Circuits, an advanced PCB one-stop-shop solution provider, will show what is the one-stop electronic assembly services in this article below.

Chapter 1: What does it have in One-Stop PCB Assembly Services?

Chapter 2: One-Stop PCB Assembly Services Provider - HITECH CIRCUITS

Part 1: What does it have in One-Stop PCB Assembly?

One-stop PCB assembly belongs to electronics manufacturing services, and it includes PCB design, PCB manufacturing, electronic components sourcing, and PCB assembly.

The collaboration model between electronics solution companies and the one-stop PCB assembly service provider Hitech Circuits is:

Electronics solution companies work on project designs for product research and development > Hitechpcba reduces the project costs through appropriate PCB design > PCB manufacturing, assembly, test, and other services > shipping.

One-Stop PCB assembly specific process of Hitech Circuits:

Step 1. PCB board designing (optional) and PCB reverse

HITECH CIRCUITS can help the customers to improve the PCB design. If you have completed the PCB design, our professional engineers will check carefully your design to make sure everything is OK. We also can design the board for the customers. we need schematic source files or netlists, structure diagrams (dxf) and design requirements. If no schematic source files or netlists, it needs to provide a package library (if no package, need to provide a component data manual).

Besides, we also can do the PCB reverse engineering. if you can send me 2 good sample boards.

1.Tell me these details (Layers, board size, raw materials.) then we can give you a quote about making Gerber files and BOM.

this is the first step. If you agree with the quote, then you can send me board;

2.after making files, then we quote production cost for you. If you don't agree the production cost, then you just need to pay us the cost of making files.

Step 2. PCB board manufacturing

Before bulky PCB manufacturing, HITECH CIRCUITS can manufacture samples according to customers’ requirement and do the DFM, DFT, and DFX (design for manufacturing, test, excellence).

The PCB manufacturing process is:

PCB material preparation and processing > laminate PCB layers on the core > generate circuits on PCB layers > AOI (automatic optical inspection) > mechanical and laser drill on PCB layers > electroplate PCB holes by VCP (vertical continuous plating) > print solder mask and surface finishes > process the PCB edges > four-terminal sensing test (for boards of defense, aerospace, medical, automotive uses)

Meanwhile, we manufacture the SMT stencils for PCB assembly.

Step 3. Electronic components sourcing

HITECH CIRCUITS has its electronic component warehouse, with commonly-used components and some discontinued ST/TI components in stock. According to your BOM, we provide all components you want.

We source the components from local and reliable electronic components factories and direct suppliers from the globe. Through regional price differences, we can provide the best prices for you. All the electronic parts components are original ones.

Step 4. PCB assembly service

Before bulky PCBA manufacturing, we assemble 5 PCB boards and randomly choose one for the first article inspection (FAI). We generate an FAI report and send it to our client. We will start bulky PCB assembly when the client reviews and approves it.

The PCB assembly process is: solder paste printing > solder paste inspection > SMT assembly (high-speed assembly and function assembly) > X-ray inspection if there is BGA > reflow soldering > AOI > THT assembly > wave soldering > functional test (optional) > IC programming (optional) > thermal aging (optional) > conformal coating (optional) > box-built assembly (optional)

Step 5. Final shipping

We have our warehouse for printed circuit boards and PCBA. We will use FedEx, DHL, or UPS to deliver the boards to you as soon as possible. (Usually, we recommend FedEx. since it is cheaper). We also have our own forwarder which can provide competitive price.

Electronics manufacturers need a dependable partner to supply the electronic chip that goes into all our smart electronic gadgets. Whether it’s a luxury car or smartwatch, a remote-controlled child’s toy or a glucose monitoring kit at your local health store, the crucial printed circuit board (PCB) is an essential component.

Manufacturing a PCB involves a series of complex steps: printing and storing circuit boards, procuring electronic components, assembly, and testing to ensure functionality to specifications. Traditionally, OEMs used a multi-vendor, multi-partner approach to PCB sourcing, manufacturing, assembly, and testing. However, this method was too cumbersome, slow, expensive and error-prone. As a result, the demand for ready-to-use PCBs snowballed, and one-stop PCB assembly services became the preferred choice for electronics manufacturers and designers.

The importance of a one-stop PCB assembly services provider

End-to-end service providers give OEMs a competitive edge. They can turn their ideas into efficient electronics products, get them out into the market before their competition, and achieve early monetization.

When working with a one-stop PCBA (printed circuit board assembly) service provider, the same vendor sources components and assembles the PCB. Maintaining a single point of contact for the entire manufacturing process eases communication in case of any problems, changes, or modifications. As a result, you can resolve issues quickly and efficiently, eliminate bottlenecks in the production process, and significantly reduce PCB production lead times.

Hitech Circuits is your ideal partner for one-stop PCB assembly services. We procure high-quality electronic components based on your PCB design. Our advanced electronics assembly solutions and superior customer service support you throughout the assembly process till the PCB board is tested and shipped to your promises.

HITECH CIRCUITS turnkey PCB solutions: Contributing to every stage of PCB production

OEMs prefer to work with one-stop PCB assembly manufacturers to provide services at every production stage:

Components procurement: Careful selection and timely procurement of components are key to an efficient PCB assembly process. The HITECH CIRCUITS procurement team studies details of the PCB design and layout before placing the orders for components to avoid problems in the layout later on.

Component placement: If the electronic components are not placed correctly on a blank circuit board, it can cause problems during assembly. It may result in incorrect soldering and can even cause shorts and failures in some or all of the automated processes.

PCB board layout: The schematic layout of the circuit board is decided during the PCB design process. Design choices affect the cost and delivery schedule of PCBs. Complex PCBs require longer procurement lead times and fabrication time. Therefore, coordination with the design team is critical to meeting cost and delivery targets. A one-stop provider can keep track of all the connections or interfaces that the design may require and accommodate them in the manufacturing schedule and costs.

Testing: HITECH CIRCUITS provides comprehensive testing services for PCB components and functionality. Our powerful tests include Automated Optical Inspection (AOI), X-Ray tests, in-circuit tests, flying probe, Jtag. We will not let any board pass through unless it’s perfect!

Hitech Circuits partners with you from the PCB design phase to maximize the benefits of DFM for product development, including making the right components selection and placement decisions, and finally through to production and testing.

The advantages of using one-stop PCB assembly services

There are many advantages to using a single company like HITECH CIRCUITS for end-to-end PCB manufacturing and assembly:

Reduce PCB fabrication and assembly costs: Since our one-stop PCB services cover all processes, including fabrication and assembly, there is no need for shipping components and boards from one vendor to another. Your Bill of Materials (BOM) cost is also optimized as we efficiently source difficult-to-find and long lead-time components. With all processes under one roof, you save on production costs.

Detect errors and issues early: An end-to-end service can spot potential errors and detect potential issues very early in the PCB assembly project. This saves time and gives you a chance to modify the design and reduce wastage, resulting in substantial cost savings.

Ensure higher quality of parts and production: It is best to get a single outsourced company to manage the entire production process for quality assurance. With multiple vendors, errors at one stage may not get communicated to the next, leading to quality issues in the end product. We provide comprehensive SMT assembly services (surface mount technology) at HITECH CIRCUITS with high-quality, ISO9001-certified equipment. We constantly review our quality management system to enhance service delivery. We select only high-quality components from proven suppliers.

Maintain easy communication with a single point of contact: When you have a single point of contact, there is better collaboration between designers, engineers, and testing teams. You don’t need to circulate design files with multiple vendors—one error in a chain of vendors can cause delays and quality issues in the final assembly phase. A single point of contact makes it easy to initiate change order changes with a simple phone call or email.

Develop, test and take products to market faster: To compete in today’s fast-paced market, you need to turn your ideas into thoroughly tested and functional products in the quickest time possible. Work with a single partner for shorter procurement lead times, smoother production, and a faster time-to-market while delivering quality products to your customers. We handle all aspects of the PCB manufacturing process so you can focus on improving the performance of your final product and designing better products!

What Is IC Programming?

[email protected] 

Integrated circuit (IC) programming is a type of computer programming in which software is created through code and then added to the IC. This normally is done by using a computer as a bridge for IC programming, because the computer can upload software into the IC. This is most commonly used for microcontrollers to control a certain device, but it also may be used for the main computer itself. There are many actions that can be coded through IC programming, and it comes down to what is being controlled.

Definition of IC(Integrated Circuit) Programmin

This is the process of loading a computer program into an IC circuit to run its function. In other words, it is a process of converting computer-encoded code into an IC that will utilize the serial communication protocol available in the device to achieve its goals. For the most part, it is considered the heart of the most important modern electronic circuits.

With IC programming, it all starts with software. Someone builds software made to control a device, and the software has to be added to the controller. If the program is not transferred, then there usually is no way for the controller to command the device to do anything, because it will not have the proper coding or procedures to exercise control. The programming normally is built with classic logic, and there tends to be many “if/then” statements.

After the IC programming is complete, the software must be added to the circuit. A separate microcontroller can sometimes be made to facilitate this task, but this is most commonly done through a computer. The computer, which also is commonly used to code the software, links with the IC and uploads the programming. This is true even if the circuit is within the computer itself.

Why do ICs need to be programmed?

From the available data, the need for IC(integrated circuit) programming is caused by the introduction of oversized circuits. Large circuits are a burden on designers and manufacturers, and to solve this problem, compact and tiny circuits that maintain the intended function need to be introduced. To meet this compact idea, the designers came up with the idea of an integrated circuit.

After integrated circuits were introduced, designers should ensure that they could communicate with other components, either as outputs or as inputs, which gave rise to integrated programming circuits as we see them today.

Nearly all instances of IC programming are done for microcontrollers, because microcontrollers typically are useless without their IC having software and instructions. Microcontrollers can conform to most instructions, are mobile and can be easily installed in most systems, so this tends to make the process easier. At the same time, computer circuits also can have new programming added to their IC, which improves the functions of the computer but typically is harder because other programming already is on most circuits.

IC programming can create a large array of commands and instructions, and there are many programming languages that can be used for this. There usually is no limit to what the programming itself can command, but there is a limit to what the device can do. For example, if the IC programming is for a stepper motor — a motor that moves according to programmed steps — then the programming cannot command the motor to watch over computer documents for user edits, because the device is incapable of this command.

IC programming is the process of transferring a computer program into an integrated computer circuit. Hitech Circuits offers IC programming service to meet the increasing customer requests from electronics industry. Besides programming service, we also provide service for IC marking, taping & reeling, dry packing, and customized package… etc. to fulfill your demands.

To sum up, IC programming is programming and loading the code into the integrated circuit, which can be achieved by offline programming and online programming. It is done following the procedure and using the special tools discussed in this article.

If you need more information on IC programming and functional testing, please contact the Hitech Circuits team. They are known for their super service and turnaround.

IC chip programming steps and method

1. Connect the programmer cable first,install the corresponding IC socket into the writer socket, and turn on the computer and the programmer.

2. Run the programming software: Double-click the “GANG-08″with the mouse (different programming sockets correspond to different burning software).

3. Choose the IC brand. After the program startup screen appears, click the “Device”menu to call up the IC brand selection table. Then select the brand corresponding to the IC to be burned, and then click “OK”.

4. Select the IC Part No: The IC Part No produced by the company, click “Run”after selecting the IC Part No l. If you want to select a jumper for the programming socket at this time, follow the computer’s prompt to jumper and jumper the line, Then click “OK”. If there is no jumper on the programming socket, it will enter the programming interface directly.

5. Load the software to be burned: Click the menu “File”, select “Load File To Programmer Buffer”, then select the software click “Open”, then select “00”, and click OK.

6. Check the software checksum (Buffer Checksum): After the software is loaded, a four-digit checksum will appear after the Buffer Checksum. This code should correspond to the “Electronic Design Document Notice” checksumto indicate the need to burn The recorded software is correct. If it is incorrect, it should be reported to the relevant department immediately for resolution.

7. Programming software: Click the “Program” button to load the IC into the IC socket, and then press the burning button on the burning socket. An “OK” will be displayed if the programming is successful, and the red “Error” will be displayed if the programming fails. The OK indicator light of each programming socket corresponds to the IC with the program. If it is on, it indicates that the IC programming is successful.

8. Make a mark, put a sticker on the IC that burned OK. If the burn failed, put it on another socket and program it again. Put it in the defective box if the IC is damaged, and make a mark.

What is PCBA Testing?

[email protected] 

PCBA testing refers to the test of electrical conductivity and input-output value based on PCBA board with electronic components.

PCBA SMT processing is very complicated and includes multiple important processes, such as PCB board manufacturing process, component procurement and inspection, SMT assembly, DIP, and PCBA testing. Among them, PCBA testing is the most critical quality control step in the entire PCBA processing process. The testing determines the final performance of the product.

In the design of PCB, there is a numerical relationship between different test points, such as voltage and current. However, the process flow of PCBA production and processing is very complex, including many important processes such as the PCB manufacturing process, component procurement, and inspection, SMT patch assembly, dip plug-in PCBA test. In the process of production and processing, various problems may occur due to improper equipment or operation. Therefore, it is necessary to use professional test equipment or a manual multimeter to test the test points, To verify whether the actual PCBA Board meets the design requirements and ensure that each product will not have quality problems.

PCBA testing is a key step to ensure the quality of production and delivery. FCT test fixture is made according to the test point program and test steps designed by customers, and then the PCBA board is placed on the FCT test rack to complete the test.

Testing is crucial to ensure high quality products are delivered to customers. Thankfully board assemblers offer multiple layers of testing and inspection to ensure high-quality, assembled Circuit boards are produced and delivered to customers. Despite all efforts to prevent errors, printed circuit board assembly is a complex process and defects sometimes occur relating to a variety of issues from incorrect component loading to failures in SMT equipment. Thorough testing and inspection occurs throughout the production process to ensure problems are captured early on, ensuring high quality and yield.

Visual Inspection of Solder Paste

Visual inspection is a vital element in ensuring problems are captured and corrected as early in the process as possible, reducing the time and cost associated with rework and wastage. Visual inspection begins with the solder application. Inspection at this stage checks for correct deposition of solder paste on pads to ensure components reflow properly. Here testing helps prevent solder bridges, open circuits or fragile joints prone to failure.

Pre and Post Reflow Inspection

Pre and post reflow inspection are important elements in quality control. Pre-reflow inspection catches placement errors at a point where they are easy to repair, avoiding repetitive mistakes early in the process. This is important with products like automotive boards where regulatory compliance require that boards cannot be reworked. Components and boards are heat sensitive and detection of errors at this stage can avoid their damage or destruction. Post-reflow inspection can be manual or with AOI.

A ‘first article’ inspection is performed on a run to ensure all SMT feeders are set up correctly and that there are no issues like worn vacuum nozzles or alignment of the vision system. Board assemblers can offer a special ‘First Article Service’ that enables a rapid and cost effective pre-production process by expediting a production of a few boards to designers for testing prior to a full run.

Post reflow BGA inspection and testing, along with other leadless parts require special considerations as the component package shadows solder joints making inspection impractical without special equipment. Inspection can be conducted by a range of devices including: computed-tomography (CT) scanning, specially angled optics microscopes, endoscopes and X-ray machines.

Flying Probe Testing

Flying probe testing is good for where a PCB testing is prohibitively expensive. Flying probe has relatively low setup cost and a test procedure can be designed and implemented in a single day. Assembled PCBs with all components placed are compared electrically against the measurements from a golden board for verification. It can conduct open, short, orientation and component value circuit checks. This can help verify correct component placement and alignment.

For PCB assembly, in order to ensure high quality, we do and provide related testing and inspection, include:

1.Manual Test

Manual testing is to directly rely on visual inspection to confirm the placement of components on the PCB assembly. This method is widely used. However, there are many components in the PCBA, and most of them are very small, which makes this method less applicable. Some functional flaws are not easy to detect, and data cannot be easily collected. Due to this, more professional testing methods are needed.

2.Automatic Optical Inspection (AOI)

Automatic optical inspection, also known as automatic visual inspection, is carried out by a special inspection instrument and is used before and after reflow. It has a relatively good effect on the polarity inspection of components and is a common method. But this method is more difficult in identifying a short-circuited PCBA.

3.Flying Probe Test

The flying probe testing has been generally welcomed in the past few years due to advancements in mechanical accuracy, speed, and reliability. The test system’s current requirements include fast conversion, low-volume manufacturing, and no fixture capabilities required for prototype manufacturing, making the flying probe testing the best choice.

4.Function Test

This is a test method for a specific PCB or unit, which is done by special equipment. Functional testing mainly includes the final product test and the latest entity model (Hot Mock-up).

5.Manufacturing Defect Analyzer (MDA)

This test method’s main advantages are low initial cost, high output, easy follow-up diagnosis, and fast and complete short circuit and open circuit tests. The disadvantage is that the test cannot detect functional problems. There is usually no test coverage indication, fixtures must be used, and the test cost is high.

How to test the PCBA board?

1. PCBA board manual test

Manual testing is to test directly by the vision and confirm the component mounting on PCB through vision and comparison. This technology is widely used. However, the large number and small components make this method more and more unsuitable. Moreover, some functional defects are not easy to be found, and the data is not easy to collect. In this way, more professional testing methods are needed.

2. PCBA board automatic optical inspection (AOI)

Automatic optical testing, also known as automatic visual testing, is carried out by a special tester. It is used before and after reflow and has a good effect on the polarity inspection of components. Easy-to-follow diagnosis is a common method, but this method is poor in short circuit identification.

3. PCBA board flying needle tester

Needle testing has been widely welcomed in the past few years due to advances in mechanical accuracy, speed, and reliability. In addition, the requirements for the test system with fast conversion and fixture-free capability required for prototype manufacturing and low-yield manufacturing make the flying needle test the best choice.

4. PCB Assembly board function test

This is the test method of a specific PCB or a specific unit, which is completed by special equipment. Functional tests mainly include final product tests and hot mock-up.

5. PCB Assembly manufacturing defect analyzer (MDA)

The main advantages of this test method are low initial cost, high output, easy-to-follow diagnosis, fast and complete short circuit, and open-circuit test. The disadvantage is that the function test cannot be carried out, there is usually no test coverage indication, the fixture must be used, and the test cost is high.

What is the testing principle of PCB Assembly by fixture?

PCB Assembly testing is a key step to ensure the quality of production and delivery. It refers to making FCT test fixtures according to the test points, procedures and test steps designed by customers, and then placing the PCBA board on the FCT test fixture to complete the test process. The test principle of PCBA is that: connect the test points on the PCBA board through the FCT test fixture(frame) to form a complete path, then connect the computer and the program tool (programmer), and upload the MCU program. The MCU program will capture the user’s input action (such as long pressing the switch for 3 seconds), and control the on-off of the adjacent circuit (such as LED flashing) or drive the motor to rotate through calculation. By observing the voltage and current values between the test points on the FCT test fixture, and verifying whether these input and output actions are consistent with the design, and so, the test of the entire PCBA board would called completed.

How about bare PCB testing? Please refer to it as below. 

When you order printed circuit boards (PCB), you know the pricey consequence of failure. The last thing you need financially is for your PCBs to suddenly drop dead -- or to have a shortened life span because of a design or QA issue.

PCB assembly testing methods are an integral part of the manufacturing process. Reputable electronics contract manufacturers (ECMs) offer a variety of PCB testing methods, but the seven main types include:

In-circuit testing

Flying probe testing

Automated optical inspection (AOI)

Burn-in testing

X-Ray inspection

Functional testing

Other functional testing (solderability, contamination, and more)

Here’s a primer on the most important types of PCB testing. This should prepare you better for discussions with your ECM:

7 TYPES OF PCB TESTING METHODS 

1. IN-CIRCUIT TESTING

In-circuit testing (ICT) is the most robust type of PCB testing in existence. The high price reflects that -- tens of thousands of dollars, though the cost will depend on board and fixture size, among other factors.

An ICT, also known as a bed-of-nails test, powers up and actuates the individual circuitry on the board. In most cases, the test is designed for 100% coverage, but you’ll get closer to 85-90% coverage. The nice thing about ICT is that the 85-90% you get is totally free of human error.

This test involves using fixed probes laid out in a way that matches the design of the PCB. The probes checks the integrity of the solder connection. The bed of nails tester simply pushes the board down on the bed of probes to start the test. There are access points predesigned in the board that allows the ICT testing probes to make connections with the circuit. They put a certain amount of pressure on the connection to make sure it stays intact.

ICT is often performed on bigger connections and ball grid arrays (BGAs).

This test is for a “mature” product with very few revisions expected. If you don’t have design-for-manufacturing as part of your goal, with the proper pads on the board, you may not be able to use an in-circuit test. Unfortunately, you can’t change your mind and move to an ICT strategy halfway through production.

2. FLYING PROBE TESTING

Flying probe testing is a tried-and-true option that’s less expensive than in-circuit testing. It’s a nonpowered type of test that checks for:

Opens

Shorts

Resistance

Capacitance

Inductance

Diode issues

The test works through the use of needles attached to a probe on an x-y grid obtained from basic CAD. Your ECM programs coordinates to match the circuit board and then runs the program.

We touched on flying probe vs. ICT being a common comparison. Each has advantages and disadvantages.

In some cases, ICT makes it unnecessary to use flying probe testing, but the PCB has to be designed to fit with the test fixture -- which means a higher initial cost. ICT can be faster and less error-prone than flying probe testing, so you might find the extra cost is worth it. While flying probe testing can be cheaper initially, it may actually be less cost-effective for large orders.

One final word of caution: A PCB flying probe test does not power up the board.

3. AUTOMATED OPTICAL INSPECTION (AOI)

AOI uses either a single 2D camera or two 3D cameras to take photos of the PCB. The program then compares the photos of your board to a detailed schematic. If there is a board that does not match the schematic to a certain degree, the board is flagged for inspection by a technician.

AOI can be useful for detecting issues early to ensure production is shut down ASAP. However, it does not power up the board and may not have 100% coverage for all part types.

Never rely solely on an automated optical inspection. AOI should be used in conjunction with another test. Some of our favorite combos are:

AOI and flying probe

AOI and in-circuit test (ICT)

AOI and functional testing

4. BURN-IN TESTING

As the name suggests, burn-in testing is a more intense type of testing for PCBs. It’s designed to detect early failures and establish load capacity. Because of its intensity, burn-in testing can be destructive to the parts being tested.

Burn-in testing pushes power through your electronics, usually at its maximum-specified capacity. The power is run through the board continuously for 48 to 168 hours. If a board fails, it is known as an infant mortality. For military or medical applications, boards with high infant mortality are clearly not ideal.

Burn-in testing isn’t for every project, but there are some cases where it makes a lot of sense. It can prevent embarrassing or dangerous product launches before they reach customers.

Just remember that burn-in testing can shorten the product’s lifespan, especially if the test puts your board under more stress than it’s rated for. If few or no defects are found, it's possible to reduce the testing limit after a shorter period to avoid over-stressing your PCBs.

5. X-RAY INSPECTION

Also referred to as AXI, this type of “testing” is really more of an inspection tool, at least for most ECMs.

During this test, an X-ray technician is able to locate defects early during the manufacturing process by viewing:

Solder connections

Internal traces

Barrels

There are 2D and 3D AXI tests, with 3D offering a faster testing period.

X-ray testing can check elements that are usually hidden from view, such as connections and ball grid array packages with solder joints underneath the chip package. While this check can be very useful, it does require trained, experienced operators.

Also, note that your ECM can’t necessarily inspect every layer of a board using an X-ray machine. It’s true we can see through the board to detect internal defects, but it’s a very time-consuming and expensive process (for both ECM and customers).

6. FUNCTIONAL TESTING

There are customers who do like a good, old-fashioned functional test. Your ECM uses this to verify that the product will power up.

This test does require a few things:

External pieces of equipment

Fixtures

Requirements for UL, MSHA, and other standards

This functional test and its parameters are usually provided by the customer. Some ECMs can help develop and design such a test.

It does take time. If you want to get your product out the door quickly, this may not be your best choice. But from a quality and longevity standpoint, functional testing can save face and save money.

7. OTHER FUNCTIONAL TESTS

There are other types of functional tests that can be used to check your PCB, depending on the circumstances.

A PCB functional test verifies a PCB’s behavior in the product’s end-use environment. The requirements of a functional test, its development, and procedures can vary greatly by PCB and end product.

Other PCB assembly testing types include:

Solderability test: Ensures surface sturdiness and increases chances of forming a reliable solder joint

PCB contamination testing: Detects bulk ionics that can contaminate your board, causing corrosion and other issues

Micro-sectioning analysis: Investigates defects, opens, shorts, and other failures

Time-domain reflectometer (TDR): Finds failures in high-frequency boards,

Peel test: Finds the measure of strength required to peel the laminate from the board

Solder float test: Determines the level of thermal stress a PCB's holes can resist

Advantages of functional PCB testing include:

Simulates the operating environment, minimizing customer cost

May eliminate the need for expensive system tests

Can check product functionality -- anywhere from 50% to 100% of the product being shipped, your need to check and debug it

Pairs well with other tests, such as ICT and flying probe

Great for detecting incorrect component values, functional failures, and parametric failures

Through Hole PCB Assembly

THT PCB Assembly Manufacturer – One-stop service

[email protected]

What’s mean for Through Hole (THT) PCB Assembly and Surface Mount Technology（SMT）PCB Assembly ?

Surface Mount Technology (SMT) is necessary for PCB assembly. If the PCB has no through-hole components, Through Hole (THT) PCB Assembly is not needed.

SMT assembly: SMT stands for surface mount technology, which is a versatile PCB assembly technology. Currently, all electronic components can be made into surface-mounted devices (SMD). SMDs are interconnected to the PCB pads with solder paste. SMT assembly is automatic.

THT assembly: THT, or PTH or DIP, means through-hole technology. The electronic components that require THT assembly have long pins. Usually, they are capacitors, fuses, and connectors. The PCB is pre-drilled, and these components' pins plug in the holes and wave reflowed. THT assembly is manual.

In the PCB assembly process, SMT assembly happens before the THT assembly.

What are the benefits of Through Hole PCB assembly?

Through-Hole PCB Assembly comes with a range of benefits including:

Withstanding stress-As opposed to SMT components, through-hole components are known for their ability to withstand mechanical and environmental stress.

Perfect for large components-Through-hole works well for large components that have to undergo high power and high voltage

High heat tolerance-Known for their high heat tolerance, they find application in a number of industries, particularly military and aerospace.

Ease of Prototyping- Through-hole PCBs also lend themselves to ease of prototyping and improved reliability

High Reliability-Through-hole PCBs are best used for high-reliability products that require stronger connections between layers.

Little surprise then, that even though surface mount components allow for denser configurations, for larger and heavier components that require strong bonds, through-hole technology has remained resilient and relevant.

What are the capabilities you offer for Through Hole PCB assembly?

We provide through-hole PCB services to a variety of industries including medical, electronics, instrumentation, and military, all thanks to our complete assembly capabilities:

• Hand soldering 

• Dual wave flow solder

• Hand Insertion of components 

• Automate axial or radial insertion

• RoHS soldering using tin-lead solder

• Use of high and low melting point solder

• Prototype build to high-volume assembly

• Functional test and automated inspection

• Support various types of PCBs including metal core PCBs, Rigid PCBs, Flex-rigid PCBs, FR4 PCBs, etc.

Disadvantages of Through Hole Assembly

Like any other manufacturing or assembling techniques, Through Hole PCB Assembly has its disadvantages too.

These include:

Longer production time-It takes a lot of time to drill the multiple holes through which the leads are expected to run.

Expensive-because the drilling process is difficult and time-consuming, it increases the cost of production

Minimizes space on the boards-drilling the holes on the surface of the board limits the routing area for tracing signals.

Also, by feeding the leads through the board, only one of its sides is usable, thus making the THT PCB a bit slower in operation speeds.

Through Hole Assembly Components – What are the Best Components for Through Hole Assembly?

Radial lead components

Axial lead components.

Types of Through Hole PCB Assembly

There are two (2) main types of the Through Hole PCB Assembly. The first is the Automated Through Hole PCB Assembly. The second is the Manual Through Hole PCB Assembly.

On the one hand, the automated variant is roundly touted to be faster and cost-effective because it takes little time to be completed. It also demands little human inputs, which makes it cost-effective.

On the other hand, the manual Through Hole PCB Assembly involves the traditional or manually-operational model of drilling the holes into the Printed Circuit Boards (PCBs). This model tends to take time and attracts more costs.

Functional tests and automated inspection for Through Hole PCB Assembly

Using automated inspection is very critical in minimizing turnaround time to ensure timely delivery of the boards.

Conclusion

As you can see, Through Hole Assembly of PCB can be time consuming.

However, in some applications, it is worth it more so when mounting heavier and bulkier components.

You can easily achieve the strength by soldering the components on the reverse side as you have seen.

In fact, it is virtually impossible to pull components assembled using Through Hole Assembly.

The good news, today’s guide has simplified the Through Hole PCB Assembly technique.

Through-hole PCB Assembly Testing and Inspection at Hitechpcba

In-Circuit Testing: 

This type of testing is conducted for high volume production lines, and helps us check every minute soldering and other components in detail.

Automated Optical Inspection: Abbreviated as AOI, these tests are performed to ensure that product is free from soldering, component, and BGA defects.

Automated X-Ray Inspection(AXI): 

This testing is performed to inspect insufficient fills, short circuits, fills, etc. The automated X-ray inspection helps reduce the number of defects and improve the quality of the Through-Hole circuit.

Burn-in Tests: 

These tests detect components’ failure or reliability in real environments.

Assisted Visual Inspection: 

Our experts use a wide range of advanced visual inspection equipment to perform a detailed inspection of soldering and component placement accuracy.

What’s difference between SMT assembly and THT assembly?

Most contract PCB Assembly manufacturers concentrate on their surface mount technology capabilities for PCB assembly. The SMT lines can be almost completely automated making it possible to run a high volume of boards with little human intervention and a low cost per board. Through whole assembly whether automated or manual is a slower process, it takes resources away from the high-volume business that many manufacturers prefer.

Only about 10 percent of the parts we buy are through-hole. Nearly 75 percent of the boards we run are mixed technology, which is a combination of through-hole and SMT parts one reason for this is that nearly half of our board assemblies are for high powered boards which use capacitors inductors and transformers to transfer energy. The size of these components is proportional to the energy they can store so for a high-power board we need to use some fairly large and heavy components and that means through-hole technology, in addition things like customer accessible connectors, that have to withstand stress as cables are connected and removed are likely to be through-hole components. Through-hole components are held in place by the pins as well as the solder so you can get a much stronger and more reliable mechanical bond than with surface mount components that have only solder to hold them in place. If a contract manufacturer is focused on higher volume SMT business, it's important to understand how they will handle through-hole components when you need them at z-axis. We run mixed technology boards every day we have a modern stuff line with a paperless process for assembly instructions and assemble in a single piece flow from the stuff line to a wave solder to inline inspection, d-paneling, qc testing. 

BGA PCB Assembly

Leading Ball Grid Array (BGA) Assembly Manufacturer in China

[email protected]

What’s BGA PCB?

BGA PCB is Printed Circuit Boards with Ball Grid Array. We use various sophisticated techniques for making BGA PCBs. Such PCBs have a small size, low cost, and high packaging density. Hence, they are reliable for high-performance applications.

What’s BGA PCB Assembly?

Ball Grid Array (BGA) assembly technology is a surface mount packaging technology applied to integrated circuits, which is often used to permanently fix devices such as microprocessors. BGA assembly can accommodate more pins than other packages such as Dual in-line packages or Quad Flat Packages, and the entire bottom surface of the device can be used as pins , instead of only peripherals available, and also have a shorter average wire length than peripheral-limited package types for better high-speed performance.

Our BGA assembly services cover a wide range, including BGA prototype development, BGA PCB assembly, BGA component removal, BGA replacement, BGA rework and reballing, BGA PCB assembly inspection, and so on. Leveraging our full-coverage services, we can help customers streamline the supply network and accelerate product development time.

Benefits of BGA PCB Assembly

Efficient Use of Space – BGA PCB layout allows us to efficiently use the available space, so we can mount more components and manufacture lighter devices.

Better Thermal Performance – For BGA, the heat generated by the components is transferred directly through the ball. In addition, the large contact area improves heat dissipation, which prevents overheating of components and ensures long life.

Higher Electrical Conductivity – The path between the die and the circuit board is short, which results in better electrical conductivity. Moreover, there is no through-hole on the board, the whole circuit board is covered with solder balls and other components, so vacant spaces are reduced.

Easy to Assemble And Manage – Compared to other PCB assembly techniques, BGA is easier to assemble and manage as the solder balls are used directly to solder the package to the board.

Less Damage to Leads – We use solid solder balls for manufacturing BGA leads. Hence, there is a lesser risk that they will get damaged during the operation.

In a word, BGA PCB assembly, have these advantages, high density, better electrical conductivity, lower thermal resistance, easy to assembly & manage are some of the advantages of BGA PCB.

Stringent BGA PCB Assembly Testing Process

To achieve the highest quality standards for BGA assembly, we use a variety of inspection methods throughout the process including optical inspection, mechanical inspection, and X-ray inspection. Among them, the inspection of BGA solder joints must use X-rays. X-rays can pass through the components to inspect the solder joints below them, so as to check the solder joint position, solder joint radius, and solder joint thickness.

Inspection of BGA PCB

We mostly use X-ray inspection for analyzing the features of BGA PCBs. This technique is known as XRD in the industry and relies on X-rays for unveiling the hidden features of this PCB. This kind of inspection reveals.

* Solder Joint Position

* Solder Joint Radius

* Change in Circular shape

* Solder Joint Thickness

What is a prototype PCB assembly?

 PCB prototyping is the experimentation pilot stage of the product which is to be mass produced at a later stage. This is more of an experiment which is done after the initial discussions and the design. This offers a pre-production analysis of the boards that are to be manufactured, reducing the possible number of errors in the PCB design. PCB prototypes help the manufacturer analyze the strengths as well as weak areas of their proposed circuit boards. Prototypes also serve as a reference point for future versions of the same product. At Hitechpcba, we handle PCB prototype assembly in quantities from one to hundred printed circuit boards.

We have acquired capabilities that enable us to serve our clients better. All these years, we have worked on many complex prototype PCB assembly projects, and we believe the following capabilities have helped us serve our clients better.

What are the benefits of a prototype PCB assembly?

Prototype PCB assembly comes with several advantages. These benefits play a major role in the facilitation of your PCB manufacturing. Some of these benefits include:

Detection of Flaws Early

With prototype PCB, you will easily detect whatever flaws are present during the product’s development stages. This will allow you to solve the issues thereby saving you some money if you had gone ahead to make the production having the flaws in them.

If you go ahead to make changes during the production, there may be a need for more technicalities, and this may be expensive.

Testing of Each Component

With a prototype, you will be able to test all your system’s elements individually before you go ahead to set it up. You should do this because it is important especially for very complex projects composed of several parts that are PCB based.

When you validate each of these components, you will be able to identify those areas having issues that you should look into. This is the only way the project can function the right way.

Reduction in Total Costs

Utilizing the prototype bare PCB for any of your projects could go a long way in reducing what you’ll have spent in total for the project. With prototyping, you will be able to notice those errors in your project and then make corrections before you start the real production.

As soon as these flaws have been checked and rectified, then you may continue with the manufacturing of your Printed circuit boards in large quantities, thereby saving you unnecessary costs.

High-Quality PCBs

Why prototyping your PCB is important is to help you test if your project will function effectively. When we talk of testing, it involves the identification of errors present and then rectifying and making corrections to them.

Therefore, the eventual PCB after the prototyping will be of high quality that surely meets standards set internationally.

Less Turnaround Time

With prototype PCB assembly, you will be able to reduce the total time used in producing your printed circuit board. While making use of prototype printed circuit boards, you’ll be able to see the errors and then make corrections before you start the actual production.

Therefore, the eventual prototype will be free of defects. This implies that your PCBs will be produced quickly by your manufacturer.

Consumer Electronics PCB Assembly Manufacturer

[email protected]

The Leading Chinese Consumer PCB & Assembly Supplier

The Leading Chinese Consumer PCB & PCB Assembly Supplier

It was common for white goods devices, brown goods devices, and smart toys to have simple, rigid boards with 1-4 layers in the past of years. Today’s consumer PCB products have become more portable. They use more complicated HDI PCB boards (at least 6 layers), flexible and stiff-flex boards. These consumer PCB applications have high-tech requirements for PCB manufacturers. For consumer PCB projects, thousands of electronic engineers choose Hitech Circuits.

We can help you get your consumer electronics projects “from design to manufacturing”

We are the best Chinese consumer PCB (circuit board manufacturer) because of our 24-hour rapid response service from our tech support and sales team. Hitech Circuits can help you with any questions about consumer PCBs. Please feel free to contact us at any time.

What Is Consumer PCB ?

Simply put, consumer PCB refers to the PCB used in consumer products like smartphones, smart TV and smart watches.

The demand for consumer PCBs has been growing ever since consumer PCBs were first introduced in the 1980s. Even small school projects or college projects use consumer PCBs nowadays.

In general, PCBs are boards on which circuit diagrams are physically implemented, so they can be used by devices easily.

As with a printer, it prints a copy of the original document or image on paper if you give it something. Likewise, the machine will print your PCB design on a board made mainly out of plastic, glass fiber, or some other materials if you upload it into it.

Most wiring is done by using a copper-coated track. Baseboards for flex PCB and rigid-flex PCB will be made from different materials to allow them to be semi- or fully flexible.

The Advantages and Disadvantages of Consumer PCBs

Before you buy consumer PCBs, here are some things you need to know:

The Advantages of Consumer Printed Circuit Board

● Compact Size and Saving of Wire: The copper tracks on the PCB make it possible to interconnect the components. The copper tracks replace the current carrying wires, resulting in a less bulky interconnection, permitting the components to be very small.

● Ease of Repair and Diagnostic: On consumer PCBs, it is easier to verify and replace a particular component that has failed. In properly designed boards, the components have clear polarity labels. Thus, convenience can be assured during both the installation and repair processes. During diagnostics, signal paths can easily be traced.

● No Short Circuits: Short circuiting of the whole device is impossible thanks to the material used in the manufacturing of PCBs. When one part stops working, then you are able to replace it with another identical part. This makes it easier to keep it going without worrying about all the other components being damaged.

● Time Savings: In the conservative technique of circuit connections, the components take a long time to connect. On the other hand, As compared to conventional circuit connections, printed circuit boards take comparatively less time to assemble.

● Immune to Movement: Each component on a printed circuit board is tightly held onto the board.

They are prevented from moving on the board by the solder flux essence, regardless of how the board moves.

● Tight Connections: Copper tracks make sure that connections are made automatically. It is very unlikely that any loose connections will occur during this process.

● Low Electronic Noise: In a properly laid out printed circuit board, the noise from the electronics will be reduced. If the layout is not done properly, then there is a high chance that the noise will hinder the circuit’s performance.

On PCBs, electrical components are organized in a way so that the current path lengths between them are as less as possible.

This means that electromagnetic waves and radiation are picked up. This means that there is less crosstalk between components and between traces. This is often a concern in electronic systems. Electrical noise can come in the form of heat, radiation, or flickering sounds.

● Low Cost: With a high demand for circuits boards, large-scale production of these PCB circuits boards is guaranteed at low costs, which means you will save on both costs and time.

● Reliability: All of the above translate to reliability in the circuit’s performance.

● Streamlined Production: Before PCB prototypes are ready for use, they need to go through a lengthy testing process. This because each issue must be examined individually and dealt with by hand. An automated design check alerts the designer to potential problems during the engineering process.

This intuitive design process means that PCBs often move into production more quickly than PTP constructions because testers know what to look for.

The Disadvantages of Consumer PCBs:

● Hard Repairing Process: It is very difficult to repair a damaged PCB, especially if traces or vias have been damaged. It is best to replace the entire board rather than repair it.

● Specific Usability: There are specific reasons for designing consumer PCBs, they cannot be used for other purposes or functions. A PCB should be designed for the purpose it will be used for, otherwise it might cause problems if it’s later changed.

● Environmental Pollution: As a result of different chemicals used in PCB manufacturing that are not good for the environment, the process of manufacturing PCBs is not environmentally friendly. Consumer PCBs are not recyclable and are mainly made from plastic like materials that pollute.

● Limited Application Area: Due to copper tracks’ thinness, consumer PCBs are only capable of carrying a limited current, so PCBs are only suitable for areas with low current requirements.

Consumer PCB Prototyping

Multiple runs are often required to test new designs or to verify a single function before moving to a more complicated design. So engineers use PCB prototypes in the early stages of design to verify the functionality of a PCB-based system. Prototyping helps in predicting success and avoiding failure for the consumer PCB. Consumer PCB prototypes are easy to produce and have a quick turnaround time. You can also detect flaws quickly. Prototyping allows you to test individual components in your room. This allows for efficient project completion by providing an accurate representation of the standard PCB performance. This helps to reduce overall project costs by allowing the designer to fix flaws earlier. There is a better final product at the end of all this.

The Circuit Board Plenum production and all different methods that pay out boards can come together is excellent, notwithstanding with proficient professionals, alter ego will be effectively properly secured that you choose the best industry with regards so this job.<\p>

Some PCBA object PCBs that are extremely versatile, this lot pertaining to panel is usually overfed directly into prostrate areas and you'll make sure that it could not necessarily issue forth a handling to relief Produced Printed Circuit Board Assembly traded when the possesses complicated attributes or maybe attributes.<\p>

Master of the men and women have au contraire idea precisely what Produced Vale hereat Assemblage signifies at length with how the authorities are usually generated. There are various hired help and women perplexed concerning the Orient planks, especially when it is not necessarily explained nicely. PCB's is many times over utilized till be able to copy along with hyperlink your electrical aspects towards the ball. Illustrations in the digital camera aspects for PCB's are usually capacitors along with resistors. People explained aspects would be the glaring impressive aspects that are connected simply by conductive avenues, trails or maybe signal files that are generated with bed linens linked with birdwatcher that are covered summarily into non conductive substrate. Whether it possesses match equally conductive along with non conductive avenues, it is sometimes generally known as Produced creating assemblee (PWB). If the panel has now cables and also other word together digital burning glass aspects, your pcb has become generally known as ingrown regimen conceit or maybe it is sometimes generally known as pcb set stretch.<\p>

The truth is, Produced Circuit Exchange Assembly is usually very affordable; however she will still be prosperous. The give thumbs up come up to is additionally higher due to attempt that you can spend. This is in line with to your thought attempt wants longer along with places. Nevertheless PCN commitment still be predictable and incredibly brisk with regards en route to Circuit Heave round Assembly. Bulk of a continuously with PCB design, your qc, for together with create prerequisites passion be dealt in conjunction with proper to the Corporation Backlinks Gadgets sectors (IPC) firm. Current the subject of PCB manufacturing, generally in the imprinted stop by are usually recognized simply by meat a birdwatcher portion a cut above the substrate, or maybe sometimes both equally an in the edges which makes a vacant PCB. After which it, your unproductive birdwatcher discharge prevail split leap one by one the short-term poor excuse may go on currently is pertinent simply by inscribing, and also the unanalyzably birdwatcher files that individuals wish in line with PCB will always be. Nevertheless, it is sometimes count on the quantity as to design PCB or maybe your growth total. There exists a technique also referred to as seeing that numerous electrograving that is a perplexed procedure which has files or possibly a slender birdwatcher part of substrate towards the straightforward substrate.<\p>
