Claim:
1. A method of operating a thermocompression bonding system, the method comprising the steps of: (a) applying a first level of bond force to a semiconductor element while first conductive structures of the semiconductor element are in contact with second conductive structures of a substrate in connection with a thermocompression bonding operation; (b) measuring a lateral force related to contact between (i) ones of the first conductive structures and (ii) corresponding ones of the second conductive structures; (c) determining a corrective motion to be applied based on the lateral force measured in step (b); and (d) applying the corrective motion determined in step (c) wherein the step of applying the corrective motion includes moving at least one of the semiconductor element and the substrate along at least one substantially horizontal direction.
