Lead-Free Interconnection For Electronic Devices, Ravi F. Saraf
Lead-Free Interconnection For Electronic Devices, Ravi F. Saraf
Department of Chemical and Biomolecular Engineering: Patents
An electronic device that is equipped with a plurality of bonding pads positioned on the device for making electrical interconnections and electrically conductive composite bumps adhered to the bonding pads wherein the bumps are formed of a composite material consisting of a thermoplastic polymer and at least about 30 volume percent of conductive metal particles based on the total volume of the metal particles and the thermoplastic polymer. The present invention is also directed to a method of making electrical interconnections to an electronic device by pressing a plurality of composite bumps of a polymeric based material against a substrate …
