PCBA Test is electrical conductivity and input/output value-based test of PCBA boards with electronic components mounted on them.

   Significance of PCBA testing

In the design of PCB circuit boards, there are numerical relationships between different test points such as voltage and current. But the PCBA production and processing process is very complex, including the PCB board process, component procurement and inspection, SMT assembly, DIP plug-in, PCBA test, and other important processes, in the production and processing process, maybe due to equipment or improper operation of various problems, so you need to use professional testing equipment or manual operation of the multimeter way to test the test points, in order to verify whether the actual PCBA board meets the design custom PCB requirements. In order to verify whether the actual PCBA board meets the design requirements, to ensure that each product will not have quality problems.

 PCBA testing is the key step to ensure the quality of product delivery. FCT test fixtures are made according to the test points, procedures, and test steps designed by customers, and then PCBA boards are placed on FCT test racks to complete testing.

   PCBA test principle

The MCU PCB board programming will capture the user's input action (e.g. long press on the switch for 3 seconds) and control the on/off of the adjacent circuits (e.g. LED flashing) or drive the motor rotation after calculation. By observing the voltage and current values between the test points on the FCT test rack, and verifying whether these input and output actions match the design, the test of the whole PCBA board is completed.

   Purpose of PCBA Check

Improve the product qualification rate.

 PCBA Check is a part of the whole production process of pcba processing, and is an important means to control product quality. With the improvement of product qualification rate, the throughput rate of the product will be significantly increased.

   PCBA Check Conditions

To prevent parts from contamination, you must choose EOS/ESD fully protective gloves or finger gloves, and wear static rings. The light source is white or fluorescent light; the light intensity must be above 100 lux and can be clearly analyzed and visible within 10 seconds.

 PCBA check method: Place the product about 40 cm from the eyes, about 45 degrees up and down, and inspect with visual inspection or triple magnification.

 PCBA check standard: Tested according to QS9000 standard.

 Sampling scheme: Single sampling according to MIL-STD-105E Class II standard type.

 Criteria for determining the inspection: Seriously present defects (CR) AQL 0%.

 A major defect: (MA) AQL 0.4%.

 A minor defect: (MI) AQL 0.65%.

   What are green PCBs made of?

With everyone's increased awareness of environmental protection and the development trend of modern electronic equipment, in order to respond to global and national strategies, circuit industries turn to environmental green PCB board production and gradually use environmentally friendly materials. Many PCBA suppliers issue lists of banned and restricted materials in green PCB board production. Besides, some companies also make lists of “not to buy” materials in environmental PCB production.

   HX technology pursues zero defects, starting from the smallest details, to fully ensure that all aspects of the customer's needs for the green PCB board product. As the quality management goal of continuously improving the service level, HX technology uses the excellent management system created by the ISO International Organization for Standardization, so that the customers can rest assured to use our green PCB board products.

   Why are PCB boards green?

The color of the surface of the green PCB board is actually the color of the solder resist. Solder resistance can prevent the component is-soldering phenomenon and can delay the device life to prevent the component line oxidation and corrosion. If you know more about electronic products, you will find that the PCB color is generally green. This is mainly because the green solder resist process is the most mature and simple, green PCB board is also more environmentally friendly.

 As for green oil, its solder resists ink is the oldest, cheapest, and most popular.

 There are many advantages of green PCB board:

 During PCB power board processing, electronic product manufacturing including board making as well as posting, during which there are several processes to go through the yellow lightroom, and green PCB board in the yellow light room has the best visual effect.

 Secondly, in SMT placement processing, the tin, placement, and AOI verification of these steps, all need optical positioning calibration. Green backplane instrument identification is more friendly.

PCBA Online Programming:

Before finishing welding, we usually program the microcontroller in the PCBA board to enable the microcontroller to achieve specific functions. PCB testing software will improve efficiency and reduce production costs.

 PCBA Test

Including ICT test, FCT test, Burn-In Test, fatigue test

 ICT Test (In-Circuit Test)： Through the test probe contacting the test point of the PCBA, the main PCBA test circuit continuity, voltage and current value, fluctuation curve, amplitude, noise, etc.

  PCB Functional Test Requirements

Before discussing design, test systems, software, and test methods, it is important to understand the "object" - the PCB product to be tested, not only the PCB or final assembly itself, but also how much will be produced, the expected failures, etc., including

 Product type

 Structure (single PCB / pre-made PCB / final product)

 Test specification plan:

 test point expected production (per line / per day / per shift, etc.)

 Expected failure type

 Obviously, the above ignores the "budget", but only after understanding the above items to determine how much a product test to spend, to figure out what is needed to PCB functional test the UUT before you start discussing funding issues, and only at this time to know how to make compromises to get the job done.

  PCB Functional Test Requirements

PCB Functional Test & Programming Quality Control

FCT Test (Functional Test):

 Firstly we need to program the prepared single-chip microcomputer (MCU) into the program IC through the burner, this step is conducting a simulation test for all PCBA tests. Then it has any questions from hardware and software, we will also be equipped with the necessary patch processing production tooling and test racks.

 Burn-In Test：

After the online PCB programming and FCT for the PCB board, we can simulate user input and output for a long time and periodically test its durability and welding reliability.

DRC Check-in Design Custom PCB

In the manufacturing industry, does the process designer need to check the design results after design custom PCB? The answer is yes.

 DRC check, also known as design rule check, which is PCB design software (EDA) used in the PCB Layout process in real time to check and find the design does not match the intended design specifications. DRC check is used to ensure the correctness of the design and meet the conventional design specifications as a starting point, is an indispensable part of the custom green PCB board design. Based on the role and purpose of the DRC, it is generally no more than 100 check line items.

 Meet the DRC check is the most basic requirements of design custom PCB, to meet the DRC does not necessarily mean to meet the manufacturability requirements.

 DFM Check-in Design Custom PCB

DFM check, also called design for manufacturability analysis, is based on custom PCB data through real 3D component models and actual manufacturing process simulation, a comprehensive design review of PCB and PCBA manufacturability before fabrication. The first time to find the design custom PCB defects or deficiencies, process difficulties, manufacturing risks, design custom PCB and process mismatch factors, etc., to ensure that the custom PCB design and process capabilities fully match. As a PCBA company, HX Technology will essentially reduce the number of trial production, save production costs,  and improve product reliability.

 DFM is a bridge between design custom PCB and manufacturing process, which belongs to the category of process design, through which you can find the mismatch between design and manufacturing process factors, assess the manufacturing difficulty, manufacturing risk, etc. These are not covered by DRC in custom circuit board design software.

 What is PCB Assembly Services

PCB assembly (pc board assembly) is one of the most important steps in PCB fabrication which includes all the components of manufacturing the complete PCB. There are two ways to make a pc board assembly; namely, Surface Mount Technique (SMT) and Through-Hole Technique (THT). SMT is a circuit assembly technology in which the pinless or short-lead surface-mounted components (SMC/SMD) are mounted on the surface of a Printed Circuit Board (PCB) or other substrate and assembled by soldering through reflow or dip soldering methods. THT uses leaded components with circuit connection leads and mounting holes designed on the printed board, and establishes long-term mechanical and electrical connections by inserting the component leads into the through-holes reserved on the PCB, temporarily fixing them and then soldering them on the other side of the substrate to form reliable solder joints.

The layers of a circuit board are put together along with a specific surface pattern so that it can be used for electronics manufacturing. PCB fabrication companies can manufacture PCBs in-house or outsource this aspect of production to a specialist. PCB fabrication process begins with design. Some PCB fabrication specialists can also design the board, using specifications provided by the customer.

 In other cases, customers develop their own files and send them to the PCB fabrication manufacturers. These files are presented in a format called Gerber file, an industry standard for recording PCB-specific details. PCB fabrication companies use Gerber files to program PCB manufacturing for their devices. A variety of techniques can be used, depending on the need for production. Custom products tend to be more expensive because they require small production runs, while generic or standard formats are less costly.

 Prototypes, produced in very limited quantities of boards, can be very expensive. And in some cases, to limit PCB fabrication cost and reduce the loss of proprietary information, the conductive foil layers are glued together before being covered with solder masks This is the basis for connecting the thin copper wires of the circuit and can be done by plating or other means. Multiple layers can be made using certain PCB fabrication methods. The finished PCB is assembled with other components and tested to confirm that it works properly before being sent to the customer.

 PCB Fabrication Process

 The PCB fabrication is a complex process that begins with a product concept and ends with a fully functional PCBA. Here is a sequence of steps of the PCB fabrication process, total of eight steps, generated by PCB fabrication companies.

 What is a Circuit Board Enclosure?

Printed circuit board enclosures is equipment to store and protect printed circuit boards, which can offer a PCB cover. In order to protect the PCB from environmental factors, adding possible consideration of electromagnetic compatibility (EMC), circuit board enclosure box is almost certain that the PCB will be placed in some form of enclosure. Inevitably, the printed circuit board enclosures will interfere with the free flow of air around the PCB and therefore also have an impact on the thermal performance of the system.

 Features of Printed Circuit Board Enclosures

The printed circuit board enclosures are completely sealed and has no holes or seams.

 The thickness of the printed circuit board enclosures is 2 mm, independent of the housing material.

 The printed circuit board enclosures are capable of dissipating thermal energy to the outside environment through convection, conduction and radiation mechanisms.

 Safety Distance Between enclosure design for PCB

 The production and processing of PCBA for the board and the enclosure design for PCB will generally have safety distance requirements. This distance can ensure that our PCBA board will not be damaged in some harsh environment.

 The safety distance between the PCBA board and mounting PCB in the enclosure includes electrical clearance (space distance), creepage distance (distance along the surface), and insulation penetration distance.

 I. PCBA board and the circuit board enclosure of the electrical clearance requirements: electrical clearance refers to the two adjacent conductors or a conductor and the adjacent motor shell surface along the shortest distance measured by air. According to the measured working voltage and insulation level, the distance can be decided.

 II. PCBA board and circuit board enclosure creepage distance requirements: creepage distance refers to the two adjacent conductors or a conductor and the adjacent motor shell surface along the shortest distance measured by the absolute insulation surface.

 III. PCBA board and circuit board enclosure insulation penetration distance requirements: it should be in accordance with the working voltage and insulation application occasions in line with the following provisions.

 For working voltage not exceeding 50V (71V AC peak or DC value), there is no thickness requirement.

 The minimum thickness of additional insulation should be 0.4mm.

 When the reinforced insulation is not subject to any mechanical stress at the normal temperature that may lead to deformation or performance degradation of the insulation material, the minimum thickness of the reinforced insulation should be 0.4mm.

 PCBA is the abbreviation of the printed circuit board assembly, that is to say, PCB empty board after SMT on the pieces, and then after the DIP plug-in the whole process, referred to as PCB assembly. PCB board SMD will have thousands of electronic components and welding test points, and finally composed of a circuit board. With many small and dense accessories, if there is a little careless in the whole PCBA production, the wrong material or detection will affect the quality of the product and a lot of waster.

 Application of PCB Assembly

 The electronics industry covers a wide range of products, including automobiles, computers, TVs, cell phones, etc. With the change of market demand and the development of technology, electronic products will become smaller and smaller, with shorter life cycle and multi-variety, small batch and integrated production. In the electronic products, PCB assembly is an important process in the electronics industry. 3C products such as computers and related products, communication products and consumer electronics are the main application areas of PCB assembly. CEA said the biggest demand comes from smartphones and notebook computers, and other products with very significant sales include digital cameras, LCD TVs and other products.

 The difference between PCB and PCBA

PCBA refers to a processing process in general, and can also be understood as a finished circuit board, that is, the PCB board processes are completed before the PCBA production.

 PCB refers to an empty printed circuit board. There are no parts on it. In a nutshell, PCBA is a finished board; PCB is a bare board.

 PCB Assembly Cleaning Introduction

 At present, in the whole unit to PCB assembly uses two cleaning methods:

 one is to use anhydrous ethanol manual brushing, using an immersion or local brushing. Manual brushing is mainly for PCB assembly with more components that are not suitable for water washing or all immersion cleaning, and more difficult to take local protective measures, such as: fiber optic connectors, etc.;

 the other is to use cleaning agent saponifier deionized water automatic cleaning, for the current miniaturization, high density of airborne PCB assembly has a better cleaning effect.

 PCB assembly from the completion of electrical assembly to its final delivery needs two cleaning processes:

 one after the completion of electrical assembly cleaning, is to timely remove the residue of solder paste agent in the welding process;

 another one is the cleaning before the three-proof spraying. In general, the module after completing the soldering is first debugged to ensure that it is trouble-free, and then subjected to relevant environmental tests after the three-proof treatment. As it will be stained in the process of single board debugging, whole machine assembly, etc., it will also be cleaned again before three-proofing.
