Claims
- 1. A bonding machine for bonding leads of lead frames in a lead frame strip to bond pads on integrated circuit dice attached to the lead frames, the bonding machine comprising:a heat block having a contact area thereon for heating the dice and the lead frames; an indexing mechanism for indexing the lead frame strip through the bonding machine so each lead frame in the strip is sequentially indexed to a position proximate the contact area on the heat block; a clamp mechanism holding sets of the leads of each lead frame indexed to the heat block contact area against the heat block one set at a time, each set of the sets of leads including fewer than all the leads, at least one set of the sets of leads including more than one of the leads; a bonding tool for bonding the leads in each set of the sets of leads held against the heat block by the clamp mechanism to bond pads on the integrated circuit die attached to the lead frame of the held leads; and at least one of a wire-bond pull test device and a wire-bond shear test device for testing wire bonds of leads of each lead frame indexed to the heat block contact area while the clamp mechanism holds other leads of the lead frame against the heat block.
