. Surface Finish A surface finish is then applied to the exposed copper traces and pads. This enhances solderability, prevents oxidation, and improves the overall reliability of the PCB

. This gives printed circuit board its distinctive green color, although other options are available. A solder mask is a thin layer of polymer that protects the copper traces that have been printed onto the board from oxidation
