ABSTRACT:
An apparatus for conveying a continuous semiconductor lead frame strip includes a guide rail for conveying a lead frame, the guide rail being divided into three portions having a vertically movable central guide rail portion opposite a heat block and a fixed first and second guide rail portions on opposite sides of the central portion. The accuracy of conveyance of the strip is not decreased by the vertical movement of the central guide rail. Clamp claws grasping and conveying the strip at each fixed guide rail portion operate within the respective fixed guide rail portions and do not move vertically with the central guide rail.
