ABSTRACT:
A thermode (12) of a thermocompression bonding head (11) is adjustably mounted to a frame (35). A bonding tip (26) of the thermode (12) rests against a reference surface (17). After an initial adjustment of the thermode (12) with respect to a bonding platform (37), the bonding tip (26) may be removed from the thermode (12) and replaced by another identical tip (26) without a need for readjusting the thermode (12) with respect to the bonding platform (37). A comparatively large interface surface area between a dovetailed groove (16) and the mating surfaces of the bonding tip (26) and a wedging action of the dovetailed section urging mating surfaces against each other minimize thermal resistance across the interface between the thermode (12) and the bonding tip (26).
