Abstract:
A printed circuit board comprising:a) a plurality of spaced apart circuit layers; b) a drill or laser formed blind hole/via extending between a surface circuit layer and at least one other circuit layer, said blind hole/via having an electrical connect layer which electrically connects said surface circuit layer to said at least one other circuit layer; c) a reflow pad for mounting a component to the surface circuit layer, said reflow pad extending over a surface part of said electrical connect layer, and also extending over the blind hole/via, the surface part of the electrical connect layer extending a short distance over the surface of the surface circuit layer such that the reflow pad is located upon that part of the electrical connect layer that extends over the surface of the circuit layer; and d) an electro-conductive material filling the blind hole/via.
