High-frequency PCB is a circuit board produced on microwave substrate copper clad board using part of ordinary rigid circuit board manufacturing methods or using unique processing methods. Due to high frequency, communication and signal transmission are carried out at a faster rate. The specifications state the minimum to maximum details of a high-frequency circuit that are necessary to understand the complexity of the board and select base material. The specifications of a circuit include electrical and environmental factors. As both work together to determine the high frequency pcb manufacturing .
