PCB high frequency board refers to the special circuit board with higher electromagnetic frequency, which 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). It is a microwave substrate The copper clad board is a circuit board produced by using part of the process of the ordinary rigid circuit board manufacturing method or using a special processing method.
PCB high-frequency board refers to a special circuit board with higher electromagnetic frequency, which is used for high frequency (frequency greater than 300MHZ or wavelength. Generally speaking, microwave high-frequency board can be defined as a circuit board with a frequency above 1GHz. The substrate material needs to have excellent electrical Performance, good chemical stability, and the loss of the substrate with the increase of the power signal frequency is very small, so the importance of the high-frequency sheet is highlighted.
  PCB high-frequency board 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?

PCB high frequency board

One, high efficiency
  High-frequency circuit boards with low dielectric constant will have very 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.
 Two, fast
  The transmission speed is inversely proportional to the square root of the dielectric constant, which means that 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.
 Three, the degree of control is large
It is widely used in high-frequency circuit boards that require precision metal material 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.
 Fourth, strong tolerance
 The 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 .
