ABSTRACT:
An apparatus for removing tie bars from between the leads of a semiconductor device during the manufacture of said device comprises a punch guide having a plurality of guide slots and a die block aligned with and spaced from the punch guide so as to provide a space therebetween. The die block is provided with a plurality of die slots which are in axial alignment with the plurality of guide slots in the punch guide. A plurality of punches are axially aligned with the guide slots and the die slots. A transmission mechanism is provided for selectively moving the die block toward the punch guide and the plurality of punches toward the die block such that the punches pierce the space between the die block and punch guide for removing the tie bars from between the leads.
