Solder surface or printed circuit board finish, Part 1: Function and properties
The solder surface, final surface or also called PCB finish, is a thin metallic or organic layer that the PCB manufacturer applies to the copper surfaces of the component connections (solder pads). The solder surface covers the exposed copper on the PCB and preserves the solderability within the guaranteed storage period of the PCBs under
