The surface PCB finish is designed to prevent oxidation of the remaining exposed copper, while the soldermask covers the majority of the circuitry. This is important because oxidized copper cannot be soldered. In rare instances, when a printed circuit board requires “body gold,” the finish is applied to the copper prior to the soldermask… Read More
