METHODS AND APPARATUSES FOR SHAPING AND LOOPING BONDING WIRES THAT SERVE AS STRETCHABLE AND BENDABLE INTERCONNECTS

摘要

A capillary tool for use in feeding, bending, and attaching a bonding wire between a pair of bond pads includes a body and a heating element. The body has an internal tube that extends from a first surface of the capillary tool to a second surface of the capillary tool. In some implementations, the internal tube has a portion with a generally helical shape that includes at least a portion of one complete revolution about a central axis of the body. The heating element is coupled to the body to provide a heat affected zone along a portion of the internal tube that heats the bonding wire as the bonding wire is fed through the internal tube.
