Patent ID: 7074648

Claim:
A method for packaging a flip-chip semiconductor assembly, comprising: providing at least one integrated circuit (IC) die having bond pads on a surface thereof; providing a substrate having electrical pads for mounting said at least one IC die thereto; placing dry conductive epoxy dots on the electrical pads on the substrate; attaching the at least one IC die to the substrate with the bond pads of said at least one IC die in contact with the dry conductive epoxy dots on the electrical pads on the substrate to form the flip-chip semiconductor assembly with the dry conductive epoxy dots forming an electrical interface therebetween; electrically testing said flip-chip semiconductor assembly through the electrical interface of the dry conductive epoxy dots; if said flip-chip semiconductor assembly fails testing, then reworking the flip-chip semiconductor assembly and retesting the flip-chip semiconductor assembly or scrapping the flip-chip semiconductor assembly if the flip-chip semiconductor assembly has already been reworked a preset number of times; and if the flip-chip semiconductor assembly passes testing, then encapsulating the at least one IC die on said substrate.
