Claim Text:
1. An automated defect inspection system, comprising: a visual inspection device for visual inputting of a plurality of first die positions having a user defined level of quality during training and for visual inputting of a plurality of unknown quality die positions for inspection; an illuminator for providing short pulses of light to each of the unknown quality die positions at a rate that is correlated with a rate at which the unknown quality die positions are aligned with the visual inspection device during movement relative to the visual inspection device to effectively freeze motion of the unknown quality die positions for visual inputting by the visual inspection device; and a computer system having processing and memory capabilities for developing a model of the plurality of first die positions having the user defined level of quality and comparing the unknown quality die positions to the model to identify defects.
