Abstract
Embodiments of the present invention improve upon component level inspection performed by pick and place machines. Such improvements include using a position sensitive device that measures the position of the placement head relative to the workpiece as the placement head travels towards and away from the workpiece during a placement cycle. The output of this sensor is used to selectably trigger the acquisition of the images used to measure a placement characteristic of the component placement machine.
