Abstract

There is high demand in industry for automated inspection of printed circuit boards (PCB’s). The major requirements for inspection systems are high speed, universality and high precision of inspection. Two major approaches have been used in the past: the reference-comparison and the design-rule verification methods. Each of them has its limitations and advantages. Recently, several authors have described algorithms which integrate both the reference-comparison and the design-rule methods [1–4].
