Abstract

The bondhead of a Wire Bonder, that serves to produce a wire connection between two connection points by means of a capillary guiding a wire, is formed as a pantograph mechanism. The pantograph mechanism comprises a first swivel arm driven by a first motor, a second swivel arm driven by a second motor and two connecting arms. With this pantograph mechanism, the movement of the capillary takes place by means of rotary movements.
