Patent ID: 8802555

Claim:
A method of manufacture of an integrated circuit packaging system comprising: providing a die paddle and a lead adjacent to the die paddle; mounting an integrated circuit having a pre-formed deformable bonding interconnect on a bond pad, over the die paddle; forming an interconnect ball having a spherical shape at the tip of a circuit end of an internal interconnect with the interconnect ball formed from the same material as the internal interconnect; attaching by embedding the interconnect ball and at least a portion of a circuit end of an internal interconnect in the pre-formed deformable bonding interconnect, the pre-formed deformable bonding interconnect in direct contact with and completely surrounding the interconnect ball, the circuit end providing electrical connectivity between the bond pad and the internal interconnect regardless of any oxidation on the circuit end by a wire bonding process free of forming gasses, and the pre-formed deformable bonding interconnect between the circuit end and the bond pad; and connecting a lead end of the internal interconnect to the lead.
