High frequency circuit board is a special PCB board with higher electromagnetic frequency

High-frequency circuit board refers to the special PCB board with higher electromagnetic frequency, which is used in the field of 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). The material copper clad board uses part of the process of the ordinary rigid circuit board manufacturing method or the circuit board produced by the special processing method. Generally speaking, a high-frequency circuit board can be defined as a circuit board with a frequency above 1GHz.

With the rapid development of science and technology, more and more equipment designs are applied in the microwave frequency band (>1GHZ) or even in the millimeter wave field (30GHZ). This also means that the frequency is getting higher and higher, and the circuit board is Material requirements are getting higher and higher. For example, the substrate material needs to have excellent electrical properties, good chemical stability, and the loss on the substrate with the increase of the power signal frequency is very small, so the importance of the high-frequency board is highlighted.
