Abstract:
A system (10) and method of determining a height and/or position of at least one element (20) on an area array device. A laser beam (30, 40) scans the area array device using at least two different laser light intensities. Reflected light (3OA, 40A) is sampled, and the height and/or position of the element (20) is determined using, e.g., optical triangulation.
