How much do you know about the different PCB surface finishing features.

The purpose of PCB surface finishing is to ensure the good behaving of printed circuit boards solderability and it’s electrical function. The original copper prefer to live in the air by oxidizing material instead of it’s original copper.So the PCB copper surface (SMT PAD,soldering PAD,etc) need to be protected from oxidizing. The normal PCB surface … Continued
