Zusammenfassung:Disclosed is an apparatus for determining an alignment of a bondhead of a die bonder relative to a workchuck. Specifically, the apparatus comprises: i) a sensor configured to measure a distance between the bondhead and the sensor; and ii) a positioning device coupled to the sensor, the positioning device being configured to position the sensor relative to a plurality of locations on the bondhead facing the sensor. In particular, the sensor is operative to measure a set of distances between each of the plurality of locations on the bondhead and the sensor, the set of distances being for determining the alignment of the bondhead. A method of determining an alignment of a bondhead of a die bonder relative to a workchuck is also disclosed.
