ABSTRACT:
Method and apparatus for inspecting a printed circuit board wherein scanned image data are digitized and analyzed according to a feature extraction method and a mutual comparison method. The result of both of the analysis methods is combined with predetermined conditions to control output devices including a CRT display or a marking device. The two complementary methods compensate each others drawbacks so that the reliability of inspection can be improved.
