PCB pads like that usually consist of a pad on top and a pad on the bottom connected to each other and internal pads by a vertical tube of plating that was applied late in the process. When used for electrical contact, it is important that the metallization has similar potentials to avoid galvanic corro-sion and non-conductive oxides. PCB copper plating—also known as copper coating, copper finish, and surface finish—has two essential functions: (1) to protect the exposed copper circuitry, and (2) to provide a solderable surface when assembling (soldering) components to the PCB. The tin or tin/lead electroplate then acts as the etch resist. Matte Tin Tin plating has been used at Tektronix as a final solderable metal finish for many years, for both aesthetic purposes and a reliable lead free alternative.
