A ROBOTIC SYSTEM FOR PCBS INSPECTION BASED ON COMPUTER VISION AND MOBILE PROBES

Abstract In this paper a new robotized inspection system for PCBs is presented. Electrical and optical tests are carried out by the system, using four mobile probes where two micro CCD cameras are mounted. This new approach becomes a costless and quick setup alternative to the currently used spiked beds for those applications of prototyping developments where maximum flexibility is demanded for the inspection system. A computer vision system provides the capacity for optical inspections where visual tests, like part presence/absence or polarity, can be performed.
