Abstract

A tool head for attaching an electrical conductor on the contact surface of a substrate, comprising a vibration exciter for generating linear ultrasonic vibrations; a bonding tool that is able to contact the contact surface and/or the conductor, a contact pressure being able to be applied to the conductor in the direction of the contact point via the bonding tool, and the conductor is able to be welded onto the contact point with the aid of the ultrasonic vibrations able to be transmitted to the contact point and/or the conductor in this manner; and a vibration conductor absorbing the linear ultrasonic vibrations of the vibration exciter; a converter being provided between the vibration conductor and the bonding tool to convert the linear vibrations into radial vibrations in such a way that the bonding tool is able to be incited to rotary vibrations.
