Abstract
A method for providing electrical contact to pads on a surface of a device involves steps of adding a first contact extension to individual ones of the pads, covering the pads and contact extensions with a layer of protective material, removing a portion of the layer of protective material such that a portion of each of the contact extensions is exposed, and applying a second contact extension to individual ones of the exposed first contact extensions. The first extensions may be any of several different kinds, including wires or solder balls, and the protective material layer provides both protection from environmental effects and added lateral strength for the connection of the first extensions to the contact pads.
