Abstract: A segment of electrically conductive wire is extended through a collet in a capillary tool and is mechanically bonded at one extended portion to a circuit point. Thereafter, an electric current having a decreasing ramp-shaped waveform is applied to the portion of the wire between the bonded circuit point and the collet to resistively heat the wire until it ruptures and forms integral balls on the ends of the wire at the rupture.
