ABSTRACT:
The horn of an ultrasonic transducer is applied with ultrasonic waves from an ultrasonic converter in such a way that standing ultrasonic waves develop in the lengthwise direction of the horn. A flange is arranged on the horn at the location of a node of the ultrasonic waves. The length of the flange is so aptly dimensioned that standing ultrasonic waves develop in the flange, when it can freely oscillate, which also have nodes. Drill holes are attached in this node so that the ultrasonic transducer is attachable to an ultrasonic welding device, in particular a wire bonder, by means of screws.
