ABSTRACT:
A circuit assembly (e.g., printed circuit board) including an insulative substrate having opposed surfaces each defining a walled opening therein. Each walled opening includes a layer of conductive material (e.g., copper) plated thereon, these openings being electrically connected through a common channel or the like, which channel in turn has been plated to include copper material therein. Located within each opening is a compliant contact pin including a compliant end portion designed to provide an interference fit within one of the respective openings and an extending portion designed for extending from the board's outer surfaces to be electrically connected to a designated external component (e.g., printed circuit board, wiring, conductive socket). Utilization of opposed pins, walled openings, and a narrow channel as defined herein allows the greater utilization of board internal volume to thus accommodate higher circuit densities particularly in the areas of the insulative board between the spaced apart, plated openings.
