Abstract
The present invention solves a problem with a wire bonding device, that during a wire bonding process, a cover at the periphery of a working hole warps upward to cause inadvertent sparking to occur across the cover that has warped upwards and a torch electrode. This invention's bonding device provided with recognition device is characterized in that insulation treatment is applied to a part of a cover positioned at the periphery of a working hole . The interior of a working region is kept, for example, at 230° C. by a heater inside a setting base , and by being placed under high temperature constantly, a part of cover warps upwards. However, since insulation treatment is applied to part of cover , a bonding device can be realized with which inadvertent sparking between a torch electrode will not occur.
