Patent ID: 7918378

Claim:
A wire bonding apparatus comprising: a support for holding wire bonding substrates; a wire bonding capillary with an opening for carrying and extruding a bonding wire and enabling wire bonding to the wire bonding substrates; a movable deflector member arranged to move generally adjacent to a facing surface of the capillary enabling the deflector member to bend an extruded length of bonding wire such that the bent extruded length of bonding wire can be articulated at different bond line angles while maintaining a constant rotational orientation for the capillary; wherein the movable deflector member having an aperture having a center with an inner surface of the aperture arranged concentrically about the center further including a plurality of wire guide features to assist positioning of the extruded length of bonding wire wherein a first wire guide feature comprises a recessed portion that lies a greater radial distance from the center of the aperture than a remaining portion of the inner surface of the aperture; and a controller configured to enable operational control of the wire bonding apparatus.
