The method involves using transducer bonding tool unit and an ultrasonic generator. The velocity plot measuring signal is determined during bonding, particularly in real time. The velocity plot measuring signal represents temporary-velocity-plot of the tip of the ultrasonic tool in oscillation direction, particularly relative to its oscillation-phase trend. An independent claim is included for a bond device, particularly wire bonder, for production and quality control of ultrasonic bonds. |
