Microwave Tech - What is high frequency PCB?

PCB high-frequency PCB refers to the special circuit board with high electromagnetic frequency, which is used in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1m) and microwave (frequency greater than 3GHz or wavelength less than 0.1M). It is a part of the process or special processing method used to produce PCB on microwave substrate copper clad laminate.

PCB high frequency circuit board refers to the special PCB with high electromagnetic frequency, which is used for high frequency (frequency greater than 300MHz or wavelength). Generally speaking, high frequency PCB can be defined as PCB with frequency above 1GHz. PCB substrate materials need to have excellent electrical properties and good chemical stability. With the increase of power signal frequency, the loss requirement on the substrate is very small, so the importance of high-frequency PCB board is highlighted.

High frequency PCB

High frequency PCB with induction heating technology has been widely used in communication industry, network technology and high-speed information processing system, which meets the requirements of many high-precision parameter instruments. Reliable high frequency PCB provides great help in actual production. So, what are the advantages of such a powerful High frequency PCB?

1, High efficiency

High frequency PCB with small dielectric constant will also have small loss, and advanced induction heating technology can meet the demand of 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.

2, 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 high-frequency PCB, it uses special materials, not only to ensure the characteristics of small dielectric constant, but also to maintain stable operation, which is very important for signal transmission.

3, Large degree of regulation

High frequency PCB, which is widely used in various industries for precision metal material heating treatment, can not only realize the heating of components with different depths, but also focus on heating according to the local characteristics. The heating methods of surface or deep level, concentration or dispersion can be easily completed.

4, It is well tolerated

Dielectric constant and medium, there will be certain requirements for the environment, especially in the south, humid weather will seriously affect the use of PCB. High frequency PCB made of materials with very low water absorption can challenge this environment. At the same time, it also has the advantages of resistance to chemical corrosion, moisture resistance, high temperature resistance and great peel strength, which makes the high-frequency circuit board play a strong performance.
