Abstract
A novel bonding tool is designed for use in conventional ultrasonic transducers. The bonding tool body is mounted in the ultrasonic transducer at an angle or in an offset holder so that the working face of the bonding tool is offset and out from under the end of the ultrasonic transducer. The axis of a wedge bonding tool body is mounted at an inclined angle of up to forty-five degrees and the tapered wedge of the bonding tool is inclined in the opposite direction so that the working face of the offset tapered wedge is in a horizontal working plane.
