1. In semiconductor manufacture a method of wire bonding semiconductor dice attached to a leadframe strip comprising:

  • providing a wire bonding apparatus having a heat block for heating the dice and leadframe strip, a clamp having multiple bond site windows spaced apart to match the spacing of the dice on the leadframe strip and a bonding tool for wire bonding;

    indexing the semiconductor leadframe strip to a precise location within the wire bonding apparatus;

    clamping multiple semiconductor dice attached to the leadframe strip between the heat block and clamp of the wire bonding apparatus;

    wire bonding bond pads on a first die to lead fingers of the leadframe strip using the bonding tool of the wire bonding apparatus placed through a first bond site window; and

    moving the bonding tool to successively wire bond each die clamped between the clamp and heat block with a single index of the leadframe.
