ABSTRACT:
A sonic, lead wire bonding tool has both bonding elements and wire cutting elements formed on its working face and a bail which limits lateral movement of the bonding wire and aids in forming the lead wire as it is payed out between between bonds. The bonding tool applies sonic energy to complete the wire bonds and to sever the wire with the aid of wire pulling force after completion of bonding.
