Abstract
The invention provides an apparatus and method for aligning a bonding tool. A force sensor having a plurality of force sensing sections is configured to measure a force generated by the bonding tool on the force sensor. Each sensing section is adapted to individually detect an amount of force from a part of the bonding tool acting on that sensing section, so that an alignment of the bonding tool may be determined.
