Abstract

A method and an apparatus for forming a contact pad on a printed circuit board over a filled plate via or blind in which an additional metallic or a non metallic coating is applied to a final surface finished plate which encapsulates the side walls of the wear resistant surface plate, and also covers the side walls of the metal layer plated onto the filled via and the wrap around plated metal which was plated in the via and onto the surface of the base metal to the extents of the pad geometry. This prevents subsequent undermining through the etching process and ensuring the integrity and reliability of the vias' electrical connection when an underlying base metal such as but not limited to copper and the surface plated metal are formed when plating metal in the via and consequently onto the surface.
