A high frequency PCB is a special type of PCB with high electromagnetic frequencies. Generally speaking, a high frequency PCB can be defined as a PCB with a frequency above1GHz. The substrate material needs to have excellent electrical properties, good chemicalstability, and with the increase of the power signal frequency, the loss on the substrate isvery small, so the importance of high frequency PCB is highlighted. High-frequency PCBcircuit boards with induction heating technology have been widely used in the communication industry, network technology field promotion and high-speed information processingsystems, meeting the requirements of many high-precision parameter instruments.
