Abstract
Many electronic entities such as integrated circuits and discrete power devices have contact pads formed from successively deposited layers of nickel and a second metal such as gold. The resulting pad structure is used to make external electrical connection such as solder connection. Problems associated with failure of such connections are avoidable by inspecting the surface of the nickel layer for excessive small particle formation.
