In the PCB industry, the most common surface treatment processes of six layer green oil electrogilding board are: tin spraying, lead-free tin spraying and oxidation resistant OSP rosin gold finger electrogilding
Definition and working principle of electroplated metal plate: electroplated metal is a process of working and processing by electrolysis to electrolyze gold onto copper surface.
Performance of the six layer green oil electric metal plate:
1. The wettability of the electroplated plate is general
2. The thickness of the electrometal is relatively thick and the flatness is good; Electrogold is mainly used for gold finger (wear-resistant), and there are many pads;
