High frequency board is a special PCB with high electromagnetic frequency. Generally speaking, the high frequency can be defined as the frequency above 1GHz. Its physical performance, precision, technical parameters are very high requirements. The high frequency PCB is often used in automobile collision prevention system, satellite system, radio system and other fields.

Electronic equipment with high-frequency is the future development trend, especially in the wireless network, satellite communications increasingly developed, information products to high speed and high frequency, and communications products to large capacity and fast wireless transmission of voice, video and data standardization. So the development of the new generation of products need more high frequency PCBs.
