ABSTRACT:
The present invention relates to a system for providing input-output paths to and from a densely crowded multi-lager PCB (printed circuit board). More particularly the invention includes a pair of modules having a plurality of spaced conductive members extending normally therethrough and with the ends projecting laterally from opposing sides. The ends of the conductive members are inserted into plated through holes in the PCB on one side and into plated through holes on cards on the other sides. The cards have circuits extending from the plated through holes to an edge as does the PCB. The two cards and PCB are plugged into card-edge connectors as a unit. The connectors may be mounted on a mother board, back panel or the like.
