Abstract

A ·fully automatic LSI wire-bonding system utilizin g image processing techniques is described. The position recognition system developed is composed of measuring stations, a reco g nition device, a minicomputer, and cassette t a pe-recorders. The position of the bonding pad is found, generally in real-time, by the recognition device and computer. The computer calculates positional data of all bonding pads and s tores them on a cas s ette tape for a subsequent wire-bonding process. The position recognition me thods discussed are composed of a thresholding al g orithm and a position-finding algorithm. Th e se methods are evaluated from the viewpoint of thresholding stability, recognition rate and positional accuracy.
