In this paper, we develop and put into practice an Automatic Optical Inspection (AOI) system based on machine vision to check the holes on a printed circuit board (PCB). We incorporate the hardware and software. For the hardware part, we combine a PC, the three-axis positioning system, a lighting device and CCD cameras. For the software part, we utilize image registration, image segmentation, drill numbering, drill contrast, and defect displays to achieve this system. Results indicated that an accuracy of 5µm could be achieved in errors of the PCB holes allowing comparisons to be made. This is significant in inspecting the missing, the multi-hole and the incorrect location of the holes. However, previous work only focusses on one or other feature of the holes. Our research is able to assess multiple features: missing holes, incorrectly located holes and excessive holes. Equally, our results could be displayed as a bar chart and target plot. This has not been achieved before. These displays help users analyze the causes of errors and immediately correct the problems. Additionally, this AOI system is valuable for checking a large number of holes and finding out the defective ones on a PCB. Meanwhile, we apply a 0.1mm image resolution which is better than others used in industry. We set a detecting standard based on 2mm diameter of circles to diagnose the quality of the holes within 10 seconds.

Saki Corporation will demonstrate its BF-3Di-Z1 3D AOI system for extra-large (686x870mm) PCBs and easy-to-program real-time software in booth 726 at SMTA International, September 27 and 28th, 2016, being held at the Donald Stephens Convention Center, Rosemont, IL. Saki's 3D AOI systems measure heights from 0-20mm with 1µm resolution, measure the surface of surface mount devices and through-hole packages from all four directions without a dead angle or shadowing, and achieve full automation with very low false calls and zero escapes.
