Integrated testing and algorithms for computer visual inspection of integrated circuits

An automated visual inspection system for Pre-Cap inspection of integrated circuits is presented. This system applys a proposed database-structural-feature technique to inspect wirebond patterns. Four algorithms, one on pre-inspection alignment, one each on inspection of "ball" bonds and "wedge" bonds, and last on inspection of "crescent" welds, together with results obtained, are discussed. A survey of the various computer visual techniques for integrated circuits is also provided.Master of Engineerin
