. (Some practitioners pre-bake components and boards to drive out moisture. This is not encouraged and should be a last resort as baking tends to build intermetallics as well as degrade the solderability by increasing oxidation levels

. If the insulation is stripped during the stripping operation, the problem can be destroying the solderability of the wire, where it will not solder or, cannot be tinned, due to the oxidation on the wire strands

. 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
