ABSTRACT:
Semiautomatic threading of bonding wire into the guide hole of a wire bonding tool is accomplished by holding the end of the wire in a reference position while its standing part is disposed in the wire feed mechanism of the machine and by activating the feed mechanism after the tool and work positioning mechanism of the machine have placed the bonding tool in line with the wire proximate to the wire end. A preferred apparatus for holding the end of the wire in place is a structure which forms a ledge and has a notch in the edge of that ledge.
