What is a high frequency PCB?

High-frequency PCB refers to a special circuit board with high electromagnetic frequency. It is a circuit board produced by using part of the ordinary printed circuit board manufacturing method on the microwave substrate copper-clad laminate or by using a special processing method. Most of the time, these high-frequency PCBs have a frequency range between 500MHZ and 2GHz. The most common applications using this PcB include electronics such as microwaves, mobile phones, and radio frequency devices. High-frequency circuit boards have been widely used in the communication industry, the promotion of network technology, and high-speed information processing systems, meeting the requirements of many high-precision parameter instruments. So, what are the advantages of such a powerful high-frequency board?

1. Fast

The transmission speed is inversely proportional to the square root of the dielectric constant, meaning that the lower the dielectric constant, the faster the transmission speed. This is exactly the advantage of the high-frequency circuit board. It uses a special material, which not only ensures the characteristics of a small dielectric constant, but also maintains stable operation, which is very important for signal transmission

2. High efficiency

A high-frequency circuit board with a small dielectric constant will have a small loss, and the advanced induction heating technology can meet the needs of the target heating, and the efficiency is very high. 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.

3. Strong tolerance

The dielectric constant and medium have certain requirements on the environment, especially in the south, where 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. At the same time, they also have the advantages of resisting chemical corrosion, moisture resistance and high temperature resistance, and great peel strength, allowing high-frequency circuit boards to play a strong performance .

4. Large adjustable degree

Widely used in high -frequency circuit boards in various industries that require heating treatment of precision metal materials. In its field of technology, it can not only realize the heating of components with different depths, but also focus on heating for local characteristics, whether it is the surface or deep layers , centralized or decentralized heating methods can be easily completed.
