Abstract
A wire brake for use with automatic wedge bonding machines which have cutting pliers arranged behind the associated bonding tool and movable along the bonding wire for detaching bonding wire from the open pliers. The wire brake includes guiding members having a plurality of deflectors that can be applied to the bonding wire, the guiding members having two planes from which the bonding wire can be laterally deflected. A central deflector is provided for deflecting the bonding wire from the planes. The central deflector projects between the two planes for guidance of the bonding wire and is displaceable transverse to the longitudinal extension of the bonding wire. Additional guiding members are arranged opposite the planes such that the bonding wire rides between the central deflector and the additional guiding members when the bonding wire is deflected.
