Abstract:
1. A method of fabricating a substrate assembly, comprising: providing a substrate having a first surface and an opposing second surface; forming a layer of resilient conductive material on at least one of the first and second surfaces of the substrate; forming a plurality of electrically isolated spring-biased electrical contacts from the layer of resilient conductive material; forming a plurality of elongate conductive traces from the layer of resilient conductive material, each elongate conductive trace associated with an electrically isolated spring-biased electrical contact of the plurality and extending therefrom, a portion of each elongate conductive trace being defined by a pair of substantially parallel cavities in the layer of resilient conductive material; deforming at least a portion of at least one electrically isolated spring-biased electrical contact of the plurality of electrically isolated spring-biased contacts from a position co-planar with the associated elongated conductive trace and adjacent the at least one of the first and second surfaces to another position extending away from the at least one of the first and second surfaces of the substrate; and treating the layer of resilient conductive material after forming the at least one electrically isolated spring-biased electrical contact to permanently enhance strength and elasticity of a portion of the resilient conductive material comprising the at least one electrically isolated spring-biased electrical contact.
