ABSTRACT:
Bonding apparatus bonds inner leads on a film carrier to outer leads. Outer lead frame stock and the film carrier bearing the inner leads and dies are fed to the bonding site. A set of inner leads and the die thereto bonded is punched from the film carrier and moved to the bonding position in a manner such that the inner leads are aligned with the outer leads. A bonding tool effects the bond. Thereafter, the next set of outer leads and inner leads and die are advanced to the bonding site.
