Patent ID: 7252515

Claim:
A method of forming an interposer for connecting an electronic module to a substrate therefor, comprising the steps of: providing an array of apertures in at least one layer of insulating material having an upper and lower surface with respective ones of said array of apertures extending from said lower surface to said upper surface and arranged to be aligned with electrical pads on an electronic module and electrical contacts on a substrate therefor; positioning in each of said respective ones of said array of apertures a resilient electrical conductor randomly wound to form a resilient wadded wire connector that extends through the aperture therefor beyond said upper and lower surface; and forming around each said resilient wadded wire connector extending beyond said upper and lower surface and the aperture therefor an elastomeric insulating material to encapsulate each said resilient wadded wire connector and allow said resilient wadded wire connector to deform under pressure extending to force said connector into said aperture.
