The name of the circuit board are: circuit board, PCB board (HDI pcb Printed circuit board), aluminum substrate, high frequency board, thick copper plate, impedance board, PCB, ultra thin circuit board, ultra-thin circuit board, printing (copper etching technology) circuit board, etc.. The circuit board makes the circuit micro and visual, and plays an important role in the batch production and optimization of the fixed circuit. The circuit board can be called printed circuit board (Printed circuit board supplier) or printed circuit board. The English name is (Printed, Circuit, Board) PCB.
