Abstract
Methods to shield conductive layer from via. A protective coating of insulating material is formed around a clearance hole in a conductive layer of a printed circuit board, so that the conductive material in a via within the clearance hole will not contact the conductive layer and create a short circuit. In one embodiment, the protective coating is sufficiently hard to deflect a drill bit being used to drill the via hole, thus protecting against misregistered drilled holes.
