Abstract
A device for establishing a bonding connection, with a bonding head mounted so as to rotate about an axis of rotation, and a transducer () mounted on the bonding head. The transducer () has a piezo actuator () for generating ultrasonic vibration, in particular a natural ultrasonic vibration. Electrodes are () provided on the piezo actuator () in such a way that the piezo actuator () can be excited by an electric field in a field direction () transverse to a polarization direction () of the piezo actuator, and as a result of the excitation and of the connection of the piezo actuator () to the fastening section () and to the tool holder (), the piezo actuator () carries out a shearing motion in a shearing plane () formed by the polarization direction () and by the field direction ().
