Application fields and advantages of PCB high frequency board

Definition of PCB high frequency board
High-frequency board refers to a special circuit board with a higher electromagnetic frequency. It is used for high-frequency (frequency greater than 300MHz or wavelength less than 1 meter) and microwave (frequency greater than 3GHZ or wavelength less than 0.1 meter). The copper board is a circuit board produced by using part of the process of the ordinary rigid Printed circuit board manufacturing method or using a special processing method. Generally speaking, a high-frequency board can be defined as a circuit board with a frequency above 1GHz.
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). This also means that the frequency is getting higher and higher, and the requirement for the circuit board materials are also 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 board is highlighted.
PCB high frequency board application field
1. Communication system, intelligent lighting system
2. Power amplifier, low noise amplifier, etc.
3. Passive components such as power splitters, couplers, duplexers, filters, etc.
4. In the fields of automobile anti-collision systems, satellite systems, and radio systems, high-frequency electronic equipment is the development trend.

PCB high-frequency circuit boards with induction heating technology have been widely used in the communication industry, network technology field promotion, and high-speed information processing systems, meeting the requirements of many high-precision parameter instruments. Reliable high-frequency circuit boards provide great help in actual production. So, what are the advantages of such a powerful high-frequency circuit board?

1. High efficiency
High-frequency circuit boards with small dielectric constants will have low loss, and advanced induction heating technology can achieve the target heating requirements with very high efficiency. Of course, while focusing on efficiency, it also has the characteristics of environmental protection, which is very suitable for the development direction of today's society.
2.high speed
The transmission speed is inversely proportional to the square root of the dielectric constant. The smaller the dielectric constant, the faster the transmission speed. This is the advantage of the high-frequency circuit board. It uses special materials, which not only guarantees the low dielectric constant, but also maintains the stable operation, which is very important for signal transmission.
3. Large degree of controllability
It is widely used in high-frequency circuit boards that require precision metal heating treatment in various industries. In the process of its field, not only can heating of different depth components, but also focus on heating according to local characteristics, whether it is surface or deep level. , Centralized or decentralized heating methods can be easily completed.
4. strong tolerance
Dielectric constant and medium have certain requirements on the environment, especially in the south, where wet weather will seriously affect the use of circuit boards. High-frequency circuit boards made of materials with very low water absorption can challenge such an environment. At the same time, they also have the advantages of resistance to chemical corrosion, moisture resistance, high temperature resistance, and great peel strength, allowing high-frequency circuit boards to exert powerful performance .

The ideal material for high-frequency boards is Rogers pcb. Because of its low water absorption, it can be used as an ideal choice for high-humidity applications. It provides customers in the high-frequency board industry with the highest quality materials and related resources, and fundamentally controls product quality. . However, in prototype pcb manufacturing or PCBA processing, Rogers/Rogers is a special kind of sheet material, which has a certain technical threshold, is difficult to operate, and is expensive. POE is a professional PCBA processing manufacturer that can meet customers' various PCB needs. Welcome to consult at any time.
