A flex circuit card with an elastomeric cable connector assembly is provided for transmitting high speed signals between two or more printed circuit boards in a high performance computer system. The flex circuit card connects a cable assembly to a printed circuit board. A conductor trace in the flex circuit card extends into an elastomeric end and terminates with a ball shaped contact which is angled to wipe against mating pads on the printed circuit card for making electrical contact. The cable assembly uses multiple wires attached to a plurality of elastomeric connectors. At least one elastomeric connector is attached to each end of the cable assembly and each elastomeric connector has a plurality of contacts which are used to mate with a plurality of pads on the surface of the printed circuit board. The elastomeric connector described in the present invention provides a high density, cable-to-board interconnection that is perpendicular to the surface of the printed circuit board.
