The process of printed circuit board from optical board to showing circuit pattern is a complex physical and chemical reaction process. This paper analyzes the last step - etching. At present, the typical process of printed circuit board (PCB) processing is "graphic electroplating". That is, a layer of lead tin anti-corrosion layer is pre plated on the copper foil to be retained on the outer layer of the board, that is, the graphic part of the circuit, and then the rest of the copper foil is chemically corroded, which is called etching.

The surface treatment of PCB striking board includes OSP, gold precipitation, bare copper, Hard zinc plating, and the most common HASL. HASL can be divided into lead-free HASL and lead HASL. These surface treatments can be done by deep sub electrons.

在PCB的制造中,层压工艺通常是指将铜箔、预浸料和芯板(内层)与准备好的电路按一定顺序层压,然后通过压机,首先在高温高压条件下热压。,将其熔合成一体,然后冷压以释放应力并确保产品平整。
