ABSTRACT:
A contacting device for making a wire connection on a microcircuit by applying ultrasonics or thermocompression. A contacting horn is provided with a capillary which, in turn, is associated with a wire clamping device for feeding or clamping the wire during movement of the contacting horn. The wire clamping device has two clamping members for grasping the wire. The clamping members are movable relative to each other for clamping the wire, and both are arranged to pivot jointly to move the clamped wire in its lengthwise direction. A controllable actuation unit is each associated with the second clamping member which moves relative to the first, and the two clamping members jointly. The clamping members may be formed as a strip for grasping the wire between outer end regions. The second clamping member is mounted on a support of the first clamping member, and its outer end is pressed by a leaf spring fastened to the first clamping member.
