Abstract
The purpose of this correspondence is to present problems and methods in automating visual inspection of printed circuit boards (PCB´s). Vertical and diagonal illumination are useful in detecting PCB patterns correctly. An algorithm comparing local features of the patterns to be inspected with those of the pattern to be referenced is proposed. An inspection system using developed technologies is also described.
