Flexible PCB

What is a Flex PCB? Flexible printed circuits, also known as flexible circuits, are sometimes regarded as bendable printed circuit boards (PCBS), but in fact, there are significant differences between PCBS and flexible circuits in terms of design, manufacturing and functionality. One common mistake made by designers is to use the same rules as those for PCBS when designing flexible circuits. Flex PCB requires a unique setup and has its own set of design rules, which the Hitechpcb team refers to as "flexibility" and has been striving to improve over the past many years.

Flexible printed circuit boards (PCBS) are an increasingly popular type of electronic interconnection. This method of connecting components in the circuit offers more design options and stronger robustness. Also known as flexible electronics, flexible circuit boards, flexible printed circuits (fpc), or flexible circuits, the conductive path of the circuit is established on a flexible plastic substrate - typically made of polyimide, PEEK, or polyester - and the components are soldered onto exposed copper pads.

Flexible PCBS can have single-layer, double-layer or multi-layer conductive copper circuits. Because the substrate is flexible, it has an advantage over rigid PCBS in packaging.

The advantages of flexible pcb There are many advantages to using flexible PCBS. The mechanical and thermal properties of the substrate open up a variety of design and performance opportunities. Most of the advantages come from the flexibility of the circuit board material and the ability to easily create complex shapes using laser cutting. In addition, the substrate material usually has better thermal performance than the materials used in rigid PCBS. The most notable benefits are as follows.

Flexible PCB Manufacturing Process The flexible PCB manufacturing process requires precision control at every step to ensure dimensional stability and consistent impedance. The general process includes:​

Base Material Cutting

CNC Drilling or Laser Drilling

Pattern Imaging and Etching

Plating (Through-hole / Surface)

RF PCB & Microwave PCB

What are RF PCBS and microwave PCBS?

Email addres: [email protected]

Rf PCBS and microwave PCBS are printed circuit boards that carry RF or microwave signals. Therefore, these types of PCBS typically operate within the frequency range of megahertz to gigahertz. Therefore, we use these frequency ranges in communication technologies ranging from mobile phones to radar.

The materials used are advanced composite materials with properties such as dielectric constant (Er), loss tangent and coefficient of thermal expansion (CTE). These materials can be mixed in the same stack to achieve the best performance and economic benefits.

The advantage of using materials with low X, Y and Z CTE is that the resulting PCB structure remains extremely stable in high-temperature environments, while operating up to 40 GHz in analog applications, allowing for the effective placement of very fine-pitch components, including in some cases, bare mold connections.

RF stands for Radio frequency, a signal with an extremely high frequency. The selection of the circuit board substrate depends on the requirements for the performance indicators of the circuit board. It can be ordinary FR4 epoxy glass fiber, or special microwave substrates such as Teflon, Alon, and Rogers materials.

With the increase in the complexity of electronic components, signal rate and high transmission frequency have become top priorities. Then, it is not surprising that the demand for high-frequency PCBS is on the rise. They can be used in various high-speed design applications that require a frequency range of 500MHz to 2GHz.

RF and microwave circuit board designs are somewhat peculiar compared to the conventional board design criteria. The parameters such as radio-frequency trace, power supply decoupling, via holes, and PCB stack-up are particularly designed to work in the radio frequencies. As a designer, you should ensure minimal interference between traces carrying radio waves and the components placed nearby. This type of interference will affect the signal transmission strength of the whole module. Therefore, the layout is designed to avoid EMI as much as possible.

What is an RF Circuit Board? In general terms, the PCB industry considers an RF circuit board to be any high frequency PCB that operates above 100MHz.Within the radio frequency class, anything above 2GHz is a Microwave PCB.

What is a microwave PCB? The main difference between RF circuit boards and microwave PCBS lies in the radio frequencies at which they operate. Microwave PCBS are classified as any RF circuit boards operating above 2GHz.Rf circuit boards and microwave PCBS are used for communication signals in any application that requires the reception and transmission of radio signals. For instance, some common applications are mobile phones and radar devices.

Application of Radio Frequency Board Rf boards have a variety of different applications, including wireless technology, smart phones, sensors, robots and security. With the emergence of new technologies that push the limits of electronic technology, the demand for RF boards is on the rise. Finding a capable RF PCB manufacturer is crucial for ensuring that circuit boards are manufactured to high-quality standards and on time. Our reputation speaks for itself. We take pride in turning the most demanding layout concepts into reality.

Considerations for RF and Microwave PCB Design The design of high-frequency circuit boards is challenging due to the requirements of signal sensitivity and thermal performance management. Compared with the standard FR4, many high-frequency PCB materials have lower thermal conductivity, which must be taken into account during layout and stacking planning.

Radio frequency and microwave signals are particularly sensitive to noise and require stricter impedance tolerance than digital circuits. Design techniques such as using ground planes and large bending radii on impedance control traces help optimize performance. Because the wavelength depends on the frequency and material properties, materials with a higher dielectric constant (Dk) can make PCB designs smaller and suitable for specific impedance and frequency ranges.

Benefits of RF PCB & Microwave PCB

RF circuit board and microwave PCB board can work on high Frequencies.

They have a stable structure. Hence, it allows them to work at high temperatures.

These have a stable dielectric constant and a low loss tangent. So, the signal travels through them with minimum impedance.

It is possible to form a multilayer board stack up. Hence, we can make smaller boards. Therefore, they give optimal performance and are cost-effective.

They allow for fabricating complex layouts. So, it is easier to assemble fine pitch components onto the board.

LED PCB Board Assembly

At Hitech Circuits Co.,Limited, we offer LED PCBs or printed circuit boards that we design expressly for mounting LEDs. Our LED PCBs are thin boards that provide physical support for the LEDs, and further help by transferring heat away from the LED bulbs. Our boards enhance the performance of the LEDs mounted on them and prevent damage to them.

Our LED PCBs, also known as MCPCBs or Metal Core PCBs, have brought great progress to the LED industry. They have been instrumental in increasing the lifespan of the LEDs while enhancing their performance significantly.

What is the LED Circuit Board assembly? Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights.

We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.

Types of LED PCBs We use SMD or surface mount device LEDs or COB or chip-on-board LEDs on most of our LED PCBs. We mount SMD LEDs on the surface of the board along with other SMD components. For COB LEDs, we arrange the dies or ICs in a circle or a regular polygon and directly bond them to the PCB, sealing them together with glue. Then we use either flip-chip or wire bonding to bond the COB LEDs to the PCB.

Advantages of Aluminum for LED PCBs Using Aluminum for LED PCBs offers many benefits like: Lower Costs Enhanced Environmental Performance Improved Durability Reduced Weight

Benefits of Aluminum for LED PCBs Aluminum is one of the most popular LED circuit board materials because it has many properties that are ideal for LED applications. Perhaps the most valuable feature of aluminum LED PCBs is their excellent heat transfer capabilities. Consistently high temperatures can damage electronics and LEDs and diminish their lifespan and performance, including the quality and color of the lights. Because of these risks, electronic devices must have adequate heat transference — a term that refers to how well thermal energy, or heat energy, can move from place to place. Aluminum conducts thermal energy relatively easily, which enables it to transfer heat away from components such as LEDs.

Heavy Copper PCB Heavy copper pcb manufacturering

Hitech is a professional heavy copper pcb, thick copper pcb board manufacturer, PCB power supplier from China, we have been associated with heavy copper pcb plating since 2000 and we have won good reputation in this industry. If you have customized heavy copper pcb needs, please don’t heisitate to conatct [email protected].

What is heavy copper PCB board Heavy copper PCB boards ( also being called thick copper board, power board etc ) are usually bonded with a layer of copper foil on a glass epoxy substrate. The thickness of copper foil is usually 18μm, 35μm, 55μm and 70μm. The most commonly used copper foil thickness is 35μm. The thickness of copper foil used in China is generally 35-50μm, and there are also thinner ones such as 10μm and 18μm; and thicker ones such as 70μm. The thickness of the composite copper foil on a substrate with a thickness of 1-3mm is about 35μm; the thickness of the composite copper foil on a substrate with a thickness of less than 1mm is about 18μm, and the thickness of a composite copper foil on a substrate with a thickness of more than 5mm is about 55μm. If the thickness of the copper foil on the PCB is 35μm and the printed line width is 1mm, then for every 10mm length, its resistance value is about 5mΩ, and its inductance is about 4nH. When the di/dt of the digital integrated circuit chip on the PCB is 6mA/ns and the working current is 30mA, the resistance and inductance contained in each 10mm printed line are used to estimate the noise voltage generated by each part of the circuit to be 0.15. mV and 24mV.

Advantages of heavy copper PCB board Heavy copper plate has the characteristics of carrying large current, reducing thermal strain, and good heat dissipation.

The heavy copper circuit board can carry large current

In the case of a certain line width, increasing the copper thickness is equivalent to increasing the cross-sectional area of ​​the circuit, which can carry a larger current, so it has the characteristic of carrying a large current.

Heavy copper circuit boards reduce thermal strain

Copper foil has a small electrical conductivity (also called electrical resistivity ), the temperature rise is small when a large current is passed, so it can reduce the amount of heat and thereby reduce the thermal strain.

Metal “conductors” are divided into: ” silver→copper→gold→aluminum→tungsten→nickel→iron ” according to conductivity.

The heavy copper circuit board has good heat dissipation

Copper foil has high thermal conductivity (thermal conductivity 401W/mK), which can play an important role in improving heat dissipation performance, so it has good heat dissipation;

Thermal conductivity refers to the heat transfer through an area of ​​1 square meter within 1H for a 1 meter thick material with a temperature difference of 1°C on both sides under stable heat transfer conditions, measured by W/m·K.

Applications of heavy copper PCB board The application field and demand for thick copper plates have been rapidly expanded in recent years, and it has become a “hot” PCB variety with good market development prospects.

The vast majority of heavy copper PCBs are high-current substrates (current x voltage = power). The main application areas of high-current PCBs are two major areas: power modules and automotive electronic components. Some of its main terminal electronic product fields are the same as conventional PCBs (such as portable electronic products, network products, base station equipment, etc.), and some are different from conventional PCB fields, such as automobiles, industrial controls, and power modules.

High-current PCBs are different from conventional PCBs in terms of efficacy. The main function of a conventional PCB is to form a wire for transmitting information. The high-current PCB has a large current through it, and the main function of the substrate carrying the power device is to protect the current carrying capacity and stabilize the power supply. The development trend of such high-current PCB is to carry larger currents, and the heat emitted by larger devices needs to be dissipated. Therefore, the large currents passing through them are getting larger and larger, and the thickness of all the copper foils of the PCBs is getting thicker and thicker. The 6 oz copper thickness of the high-current PCBs manufactured now has become normal;

The application areas of heavy copper circuit boards include: mobile phones, microwaves, aerospace, satellite communications, network base stations, hybrid integrated circuits, power supply high-power circuits and other high-tech fields.

High Density Interconnect PCB

What is a high-density interconnection PCB board HDI is the abbreviation of High Density Interconnection and is a technology in the production of printed circuit boards. High-density interconnect PCB boards are circuit boards with a relatively high line distribution density, which are manufactured using micro-blind and buried via technologies.

HDI includes the use of fine features or signal traces and Spaces of 0.003 "(75 μ m) or smaller, as well as laser drilling blind holes or embedded micro-hole technologies. Micro-vias allow the use of micro-interconnects within a PCB from one layer to another to create additional routing density or reduce form factor by using smaller pad diameters.

HDI pcb boards are compact products designed for small-capacity users.

Advantages of high-density interconnected PCB boards

It can reduce the cost of PCB: When the density of PCB increases to more than eight-layer board, it is manufactured by HDI, and its cost will be lower than that of the traditional complex pressing process. Increase circuit density: has better interconnection than that of traditional circuit boards and parts Conducive to the use of advanced construction technology Have better electrical performance and signal accuracy Better reliability Can improve thermal properties It can improve radio frequency interference ( RFI ), electromagnetic wave interference ( EMI ), electrostatic discharge ( ESD ) Increase design efficiency

Applications of high-density interconnected PCB boards

While electronic design is constantly improving the performance of the whole equipment, researchers are also working hard to reduce its size. In small portable products ranging from mobile phones to smart weapons, “small” is an eternal pursuit. High-density interconnection (HDI PCB) technology can make terminal product designs more compact, while meeting higher standards of electronic performance and efficiency. HDI PCB board is widely used in mobile phones, digital cameras, MP3, MP4, notebook computers, automotive electronics, IC carrier boards and other digital products, among which mobile phones are the most widely used.

High density PCB is used extensively in applications and industries including

Cell phone GPS Telecom Semiconductor Automotive Military Medical Instrumentation Note book computers IC Carrier board Healthcare

What is a rigid-flexible pcb board? Rigid-flex PCB board is a type of circuit board that combines flexible and rigid circuit board technologies in application. Most rigid-flexible boards are composed of multiple layers of flexible circuit boards, which are connected to one or more rigid boards from the outside and/or from the inside depending on the design of the application. Flexible substrates are designed to be in a constant flexed state, usually forming flexed curves during the manufacturing or assembly of rigid-flex PCBS.

Hitech rigid flex pcb manufacturing process

After the production of FPC flexible boards is completed, the production of Hitech rigid-flexible pcb boards can be accomplished through the following processes.

Punching

Drill holes on FR4 and PP film, and the design on the alignment hole is not the same as the general through hole. After the punching is completed, browning is required.

Riveting

Laminate copper clad laminates, PP adhesives, and FPC circuit boards and place them neatly. The original old process is to laminate and pressing step by step, but it is a waste of time. After many attempts, we found that the stacking process can be completed once.

Laminate

This is a relatively complete step in the production of rigid-flex pcb board. Most of the materials are integrated for the first time. First, the bottom layer is copper clad laminate and PP film, above are the FPC flexible board produced in the previous process, and a PP film is placed on the FPC flexible board, then place the last layer of copper clad laminate. All materials to be laminated are placed in order and pressed together.

Trimming

That is to remove the part of the circuit board where there is no circuit at the edge of the circuit board currently and in the future. Afterwards, it is necessary to measure whether the material has excessive expansion and contraction. Because the PI used in the production of flexible boards is also expansion and contraction, this has a very large impact on the production of circuit boards.

Drilling

This step is the first step to turn on the entire circuit board, and the production parameters should be produced according to the design parameters.

Desmear

First, remove the scum generated by the drilling of the circuit board, and then use plasma cleaning to clean the through holes and the board surface.

Immersion copper

This step is the process of electroplating through holes, also known as hole metallization. Realize through-hole power conduction.

Plate plating

Partially electroplating copper on the upper surface of the electroplating hole makes the copper thickness above the through hole exceed a certain height of the copper clad board surface.

Outer dry film positive film production

The same as the production process of the anti-corrosion dry film of the FPC board, the circuit to be etched on the copper clad board is made. After the development is completed, check the circuit.

Graphic plating

After the initial copper sinking, pattern electroplating is performed, and the current time and copper plating wire are used according to the design requirements to reach a certain electroplating area.

Alkaline etching

Print solder mask

This step has the same effect as the FPC board protective film. We see that the PCB rigid board is generally green. This step is generally called green oil printing. After the printing is completed, the inspection is carried out.

Open the cover

Cover opening, which is the area where the FPC board is located, but the area not needed by the rigid board is laser cut to expose the FPC board.

Curing

It is also a baking process.

Surface treatment

Generally, at this time, a rigid-flex PCB board has been manufactured, and only the metallization treatment is required on the surface of the circuit board, which can play a role in preventing wear and oxidation. Generally, this process is to soak the circuit board in a chemical solution, and the metal elements in the solution are densely distributed on the circuit board circuit.

Characters printing

The positions of the parts to be assembled and some basic product information are printed on the rigid-flex board in the form of characters.

Test

This is a process of checking whether the circuit board is qualified. The test items are tested for electrical properties according to customer requirements. The tests generally include impedance test, open and short circuit test and so on.

Final inspection

Packaging and shipping

There are many ways to package circuit boards. Generally, Hitech use packaging bags to separate them, and then use a vacuum packaging machine to vacuum package the rigid-flex PCB boards .

Rogers RF PCB

Hitech is a professional manufacturer of high-frequency pcb boards in China. Our high-frequency PCBS (RF PCBS) are widely used in wireless networks, wireless communications and satellite communications. Especially with the popularization of 4G and 5G networks, the market demand for RF PCBS has intensified. For some special high-frequency PCB materials (such as Teflon PCB materials and Rogers PCB materials), we have sufficient inventory. If you are looking for a high-frequency pcb manufacturer in China, please contact [email protected].

What is a high-frequency PCB board High-frequency PCB boards are special circuit boards with relatively high electromagnetic frequencies. Generally speaking, high frequency can be defined as frequencies above 1GHz. Its various physical properties, precision and technical parameter requirements are extremely high, and it is often used in fields such as automotive anti-collision systems, satellite systems and radio systems.

With the rapid development of science and technology, more and more equipment designs are applied in the microwave frequency band (>1GHZ) and even the millimeter-wave field (30GHZ), which also means that the frequency is getting higher and higher, and the requirements for circuit boards are also getting higher and higher. For instance, the substrate material needs to have excellent electrical properties, good chemical stability, and as the frequency of the power signal increases, the loss on the substrate is very small. Therefore, the significance of high-frequency PCB boards becomes prominent.

The advantages of high-frequency PCB boards

1.High efficiency

High-frequency PCB boards with a small dielectric constant will have very low losses, and advanced induction heating technology can achieve the target heating requirements with very high efficiency. Of course, while emphasizing efficiency, it also features environmental friendliness, which is highly suitable for the current development direction of society.

Fast transmission speed

The transmission speed is inversely proportional to the square root of the dielectric constant. That is to say, the smaller the dielectric constant, the faster the transmission speed. This is the advantage of high-frequency printed circuit boards. It adopts special materials, which not only ensure a low dielectric constant but also maintain stable operation, which is of great significance for signal transmission.

Strong controllability

High-frequency PCB boards are widely used in various industries that require heat treatment of precision metal materials. During the process of its field, not only can components at different depths be heated, but also, based on local characteristics, whether it is the surface or the deep layer, focused heating can be carried out. Both centralized and decentralized heating methods can be easily accomplished.

Strong tolerance

Both the dielectric constant and the medium have certain requirements for the environment. Especially in the south, the humid weather will seriously affect the use of circuit boards. High-frequency circuit boards made of materials with extremely low water absorption can challenge such an environment. Meanwhile, they also have the advantages of chemical corrosion resistance, moisture-proofing, high-temperature resistance, and high peel strength, which enable high-frequency circuit boards to exert powerful performance.

The advantages of the full turnkey PCB assembly service

Shorter delivery time

As the basic form of electronic assembly, PCB assembly mainly includes three stages: PCB manufacturing, component procurement and PCB assembly. Traditionally, you should quote and confirm the design documents to the sales and engineers working for PCB manufacturers, then to the component distributors, and finally to the PCB assemblers. This series of quotations and confirmations only requires you to spend time contacting different partners. If these partners come from different countries, you must overcome some problems, such as time zones and communication habits. However, full turnkey PCB assembly is an efficient form of electronic assembly. Once the full turnkey PCB assembly is determined, the overall assembly quotation and the indispensable issues that hinder smooth manufacturing will be raised, thereby reducing three communications to one and greatly improving the electronic assembly efficiency of Haike Circuit Co., LTD.

Lower cost

Another advantage of the full turnkey PCB assembly service is the reduction of overall costs. When it comes to electronic assembly, packaging services are usually cheaper than assembly services. At least you can save on shipping costs because you don't need to send the manufactured PCB boards and electronic components to the assembly workshop. Furthermore, due to the long-term cooperation between experienced electronic assemblers and component manufacturers or distributors, they are usually able to provide reliable components at relatively low costs. Therefore, component procurement may become easier and more customer-friendly.

Transparent monitoring

When it comes to the electronic assembly process, monitoring the manufacturing stage of the product is both important and challenging, as it is entirely related to the product's performance and time to market. Full turnkey PCB assembly enables engineers to know what they have accomplished at each stage and have a better understanding of their status to achieve better final product performance.

Who can benefit the most from our turnkey PCB assembly service?
