ABSTRACT:
The present invention discloses a wire bonder that does not require bonding tool replacement to be performed by an experienced worker, is not bothersome and can be completed in an extremely short time, while also enabling time management of the degree of wear of the bonding tool and so forth to be performed reliably, so as to realize improved work efficiency and yield, as well as being able to demonstrate various other effects. In addition, the present invention also discloses a bonding arm and bonding tool that contribute to the achieving of these effects. The above effects are obtained by adding a tool replacement device that removes a used bonding tool (capillary) installed in a bonding arm and installs a new bonding tool. In addition, the above effects are obtained with respect to the bonding arm and bonding tool by forming a tapered surface that guides their mutual insertion.
