Introduction of PCB proofing printing process

PCB board printing process mainly passes through equipment, pads, vias, routing, silk screen printing, solder resist positioning holes.

PCB board: the component welded on the PCB board, which is also the role of PCB. It is presented on the PCB board in the form of pad and silk screen.

Welding board: electrically connect the pins of the meta equipment to the board, which corresponds to the pins of the equipment.

Wiring: the signal line connecting the pins of the equipment, depending on the signal nature, current size, speed, etc., and the length and width of the wiring.

Via: assuming that the PCB board circuit cannot complete all signal routing on one layer, the signal lines must be connected across layers through the via method. The mode and aperture of the via depend on the signal characteristics and the requirements of the processing technology.
