What is a high frequency PCB board High frequency PCB boards are special circuit boards with higher electromagnetic frequencies. Generally speaking, high-frequency can be defined as frequencies above 1GHz. Its various physical properties, accuracy, and technical parameters require very high requirements, and are often used in automotive anti-collision systems, satellite systems, radio systems and other fields.

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

Applications for High frequency PCB High frequency rigid and flex PCBs are used in many products and across many industries, including:

Cell phone Telecommunications Military and aerospace RF microwave Automotive (mainly LIDAR, which is a mini radar that communicates a vehicle’s surroundings) High-density interconnect and high-speed design applications

Hitech Circuits Capabilities for High Frequency PCBs Trace width – 2 mil Spacing air gap – 3 mil IPC class – 2/3 Net List test – Flying Probe Testing & Inspection – AOI, TDR, Differential Impedance Routing & Drilling – Scoring/routing, countersink/counter bore, laser routing, blind/buried vias, micro vias, stacked vias Lamination – 1-40 layers, Sequential lamination, Vacuum lamination Plating – Non-conductive/conductive via fill, Castellation, Plated radii, Plated edges, Plated milled cutouts, Soft bonding gold, hard gold body, immersion gold, ENTEK (OSP), Immersion silver, HAL (standard/Lead-free) Materials – Rigid, Rigid-Flex, Flex, Kapton, high-speed and RF materials, mixed materials

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.

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.

Email address: [email protected]

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)

Coverlay Lamination and Curing

Stiffener or PSA Attachment

Profiling and Punching

Electrical Testing and Visual Inspection

Structure of a Flexible PCB

Dielectric Substrate Film

Electrical Conductors

Protective Finish

Adhesive MaterialAdhesive materials, such as polyethene or epoxy resin, are used to bond the layers of the circuit together.

Applications of Flex PCB Flexible Printed Circuit Boards are widely accepted across various sectors due to their amazing properties.

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.

Email：[email protected]

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.

Applications of LED PCB Assembly: Lighting Systems Automotive Electronics Consumer Electronics Medical Devices

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.
