Patent ID: 8525346

Claim:
An electrical interconnect providing an interconnect between contacts on an IC device and contact pads on a printed circuit board (PCB), the electrical interconnect comprising: a substrate comprising a plurality of through holes extending from a first surface to a second surface; a resilient material located in the through holes, the resilient material including openings extending from the first surface to the second surface; a plurality of discrete, free-flowing conductive nano-particles located in the openings of the resilient material, the conductive particles being substantially free of non-conductive materials; a plurality of first contact members at least partially located in the through holes adjacent the first surface and electrically coupled with the nano-particles; and a plurality of second contact members at least partially located in the through holes adjacent the second surface and electrically coupled with the nano-particles, wherein at least the first contact members are configured to pivot in the through holes relative to the substrate while being supported by the resilient material and the nano-particles.
