Patent ID: 8035038

Claim:
A printed circuit board, comprising: a plurality of layers configured in a stack so that the plurality of layers has a top layer and a bottom layer and at least one conductive layer; a hollow via extending through at least one of the plurality of layers; within the hollow via, a conductive material applied to a surface defining the hollow via, and a conductor coated with non-conductive material; wherein the top layer and bottom layer are covered by dielectric layers and the top layer and bottom layer are plated with a conductive material; and wherein the hollow via is a blind via, such that the conductor of the hollow via connects two of the plurality of layers, at least one of which is an interior layer, while the other layer of the two layers is one of the top layer and the bottom layer, while the conductor of the hollow via does not connect the conductive material on the top layer to the conductive material on the bottom layer.
