ABSTRACT:
A bonding head of the type having a bonding tool mounted in the bonding tool holder is provided with a pivotable wire clamp which is movable toward and away from the rear of the bonding tool. The wire clamp is pivotally movable to three distinct positions by a single solenoid. The wire clamp is opened and closed by a second solenoid. The solenoids are mounted on the pivot axis of the bonding tool holder in a manner which substantially prevents the shock force of actuation of the solenoid from being imparted into the bonding tool holder or the bonding tool during a bonding operation.
