High-frequency PCB

Advantages of HF PCB

1.  High-frequency PCB has a small dielectric constant and a small loss. Advanced induction heating technology can achieve the target heating needs with very high efficiency. At the same time, high-frequency PCB also has environmentally friendly characteristics, which is very suitable for the development direction of today's society.

2. The transmission rate is inversely proportional to the square root of the dielectric constant, which means that the smaller the dielectric constant, the faster the transmission rate. High-frequency PCB uses special materials, which not only ensures the characteristics of small dielectric constant, but also maintains stable operation, which is very important for signal transmission.

3. High-frequency PCB is widely used in various industries that require heating treatment of precision metal materials. In the process of its field, not only can the heating of components of different depths be achieved, but also the heating can be focused on local characteristics, whether it is surface or deep, concentrated or dispersed heating pipes, can be easily completed.

4 High-frequency PCB made of materials with extremely low water absorption can challenge humid environments, and also has the advantages of resisting corrosion from chemicals, moisture resistance, high temperature resistance and great peeling strength, allowing high-frequency PCB to play a powerful role.

Application fields of HF PCB
