Abstract:
A method of pick-and-place alignment comprises (a) determining a pick location of a device from a tray of devices; (b) determining place location of the device using an up-looking camera; and (c) determining offset error for the device by comparing the pick location and the place location. The method may further comprise repeating steps (a)-(c) for additional devices on the tray of devices; and generating an offset map for alignment of devices on the tray. The method further uses the offset map to make pick and place corrections during runtime.
