Computer vision techniques have been developed and implemented for automatic optical inspection (AOI) of multichip modules with thin films. A case study, detailing the application of the techniques based on an Orbot TF501 visual inspection system platform for a high density grid of circular pads, is presented. The techniques presented here are capable of detecting electrical and non-electrical defects such as near shorts, wrong metallurgy, contamination, etc
