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.

Abstract: A circuit is connected to an ultrasonic transducer being fed by a constant current or constant voltage power supply. By rectifying, integrating, and amplifying the transducer coil voltage an output signal that is a function of the transducer and load impedance is provided that can be displayed so as to determine the operating condition of the ultrasonic apparatus.

Abstract: A circuit is connected to an ultrasonic transducer being fed by a constant current or constant voltage power supply. By rectifying, differentiating, and amplifying the transducer coil voltage an output signal that is a function of the transducer and load impedance is provided that can be displayed so as to determine the operating condition of the ultrasonic apparatus.

Abstract: A method and apparatus for monitoring parameters indicating the quality of an ultrasonic weld process. A signal that is the function of the transducer and load impedance is first operated on by taking its logarithm. That signal is differentiated to provide a signal indicative of the smoothness of the machine movement; the negative portion of the machine signal is looked at during a selected time frame to detect the weld. The logarithm of the impedance signal is also integrated to provide a signal indicating the cleanness of the weld. The transducer voltage or current can also be monitored to assure that the desired amplitude is applied over an optimum time period.
