Because copper is easy to oxidize in air, the oxide layer of copper has a great influence on soldering. It is easy to form false welding and false welding. In serious cases, it will cause the pad and components cannot be welded. Therefore, PCB will have a process in manufacturing, coating (plating) on the pad surface to protect the pad from being oxidized.
