ABSTRACT:
A transducer assembly and wire bonding method has a vibration unit for generating an ultrasonic wave. A body section is coupled to the vibration unit for transferring the ultrasonic wave. A tapered horn is coupled to the body section for transferring and concentrating the ultrasonic wave. A capillary is coupled to a front section of the horn. The capillary has a channel running the length thereof. A wire is inserted through the channel. A discharge device is coupled to the capillary for forming a ball on the wire for wire bonding.
