Abstract	:	An automated robotic inspection system for electronic manufacturing has beendeveloped to identify pin defects of IC packages mounted on printed circuit boards usingsurface mount technology. The automated robotic inspection system consists of tworobots, a computer. a CCD camera with h m e grabber for image acquisition. and acustomized windows program using neural network for on-line defect identification.Gray scale images of the pins on IC packages are acquired using ambient light. Theimages are filtered and formatted to appropriate size, so that Matlab neural network toolcould be used. The images are used to train neural networks using Matlab's BayesianRegularization module. Optimal network was found to be a single-layer network withthree outputs for each IC investigated. The weights and biases of each of the ICsinvestigated and the matrices of gray scale values for the IC images are saved as textfiles. A customized winuows program uses these text files for on-line defectidentification. The defect identification for the networks was found to be 100 percent for.-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
