The present invention concerns a self locking system for holding a wire bonding tool in a wire bonding transducer and comprises an unitary cam key rotatably mounted in a cam key aperture extending through an anti-node end of an ultrasonic transducer. A cam surface on the cam key is operable to lock a bonding tool mounted in a substantially vertical bonding tool aperture when rotated less than 360.degree. in said cam key aperture.

Self locking key for ultrasonic transducers

A low mounting impedance ultrasonic transducer for mounting on a bonding machine comprises a prior art type transducer having a modified mounting flange which includes one or more elongated apertures in the mounting flange or the transducer body to isolate transverse radial stress in the transducer body from entering into the mounting flanges and coupling to the bonding machine.
