ABSTRACT:
A three dimensional stack of printed circuit assemblies (10,12) provides electrical interconnection or bussing between layers of the stack by means of a composite contactor (34, 35, 36, 77, 79, 81, 83) formed of a shape-memory core (90) having a number of highly electrically conductive resilient wires (92, 94) wrapped around it. The shape-memory core (90) has a low temperature configuration that is substantially straight and enables the contactor assembly or core (90) and wires (92, 94) to be inserted into vias (30, 31, 76, 78, 80, 82) extending through this stack of layers with little or no insertion force. When heated above its phase change temperature, the shape-memory core (90) assumes a sinuous configuration which tightly presses the encircling conductive wires (92, 94) against the electrically conductive interior surfaces of the vias (30, 31) to provide mechanical and electrical contact from layer to layer.
