Abstract

The invention is a fine line electrical cable with two ends having a plurality of first conductor lines in a plane. The lines of the cable are embedded in an insulating laminate material, are closely spaced at one end to be compatible with the closely spaced contacts from IC chips and are fanned out along the length of the cable to the other end where the lines are spaced somewhat apart and compatible with conventional electrical connectors. Contact posts extent from each line end so that external connections may be made with the IC chips and the conventional connectors. At least one second conductor line may be embedded within the other side of the laminate material and appropriate contact posts extend from the line ends so that external connections may also be made at these locations. A method for fabricating the fine line elecrical cable is also disclosed.
