Patent ID: 7261230

Claim:
A method of electrically connecting a first device to a second device with an insulated wire, the method comprising the steps of: forming a first bond by wirebonding a first end of the insulated wire to a first bond pad of the first device, thereby electrically connecting the bond wire and the first device; moving a tip of a capillary holding the bond wire over the surface of second bond pad of the second device such that the bond wire is rubbed between the capillary tip and the second bond pad horizontally thereby tearing the bond wire insulation so that at least a portion of a metal core of the wire contacts the second bond pad, wherein the capillary has a roughened tip that enhances abrasion of the insulation during said moving step; and bonding at least the exposed portion of the bond wire to the second bond pad via thermocompression bonding, thereby electrically connecting the first device and the second device.
