Abstract:
1. A die bonder comprising: a bond head mount; a bond head connected to the bond head mount, the bond head including a collet for picking up a die and bonding the die at a bonding site; a first motor connected to the collet by a shaft for driving the collet in driving directions towards and away from the bonding site; a second motor connected to the bond head mount for driving the bond head in directions parallel to the driving directions of the first motor; a rotary motor operatively connected to the collet for rotating the collet about a rotational axis that is parallel to the driving directions of the first motor; wherein the shaft is configured to decouple the bond head from the bond head mount after the die contacts the bonding site, wherein after decoupling the first motor is operative to drive the shaft to slide, with respect to the bond head mount, to thereby provide a bonding force to bond the die at the bonding site.
