Abstract
An inspection system determines if leads of a semiconductor device are in proper positions. Images from at least two sides of the semiconductor device are captured along with calibration marks formed in the side of a track upon which the semiconductor device is mounted. All leads and calibration marks are captured in a single video image, the images from one side of the semiconductor device being off set from the image from the other side.
