This process which is primarily performed by automatic optical inspection (AOI) system ensures the functionality and quality of manufactured products. In this paper, the pattern recognition algorithms proposed in the literature for the inspection of defects using AOI are reviewed. The review focuses on segmentation algorithms, choice of features and feature extraction algorithms as well as the types of classifier and their relative classification performance. The review spans a 20 year period from 1990 to 2011. The results of the review suggest that solder joint defect is the type of defects mostly investigated and that the trend is moving towards combining the results of more than one classifier to improve classification accuracy and robustness. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE). %K AOI; Automatic optical inspection; Classification accuracy; Classification of defects; Classification performance; Detection algorithm; Electronic manufacturing; Feature extraction algorithms; Manufactured products; Pattern recognition algorithms; Segmentation algorithms; SMD-PCB; Solder-joint defects; Surface mount device, Algorithms; Classifiers; Computer vision; Feature extraction; Image analysis; Image segmentation; Optical testing; Organic pollutants; Polychlorinated biphenyls; Printed circuit boards, Defects
