摘要： The invention provides an apparatus and method to calibrate a clamp, such as a wire clamp, which is suitable for use with a wire-bonding machine for semiconductor devices. A contact means is arranged to be contacted by an arm of the clamping device and a sensing mechanism is positioned in operational relationship with the arm. An indexing means is adapted to change positions of the clamping device relative to the contact means incrementally as said arm maintains contact with the contact means. The sensing mechanism is capable of sensing feedback from said arm at various positions of the clamping device relative to the contact means. The apparatus is particularly suitable for measuring a clamping force and/or a clamping gap between clamping arms of the clamping device.

摘要： A bonding apparatus is provided that comprises a bonding tool for bonding wire onto an electronic device secured by a clamping device. The clamping device is locatable at a first position to clamp the electronic device during bonding and a second position at a raised height to release the electronic device for indexing. A flame-off torch is locatable adjacent to the bonding tool and is operative to produce sparks to melt a tip of the wire for bonding. An actuator is further provided that is operative to lower the flame-off torch close to the electronic device during bonding and to raise the flame-off torch away from the electronic device during indexing so as to provide a height clearance between the flame-off torch and the clamping device at its second position.
