Claim:
1. A method of forming a wire bond having a free end, comprising: joining a base end of a metal wire to a conductive element at a surface of a first component, the base end of the metal wire proximate a surface of a bonding tool adjacent an aperture through which the metal wire extends; drawing a predetermined length of the metal wire out from the aperture; then using the surface of the bonding tool to plastically deform a region of the metal wire between the surface of the bonding tool and a metal element at the surface of the first component; and then using the bonding tool to apply tension to the metal wire to cause a first portion of the metal wire having the base end joined to the conductive element to detach from a remaining portion of the metal wire at the plastically deformed region, the first portion forming the wire bond extending from the base end to the free end of the wire bond remote from the conductive element, wherein a plurality of conductive elements including the conductive element and a plurality of metal elements including the metal element are at the surface of the first component, the conductive elements and the metal elements being arranged in pairs along the surface, and wherein the conductive element with which the wire bond is joined is in a first one of the pairs.
