Template based printed circuit board (PCB) inspection needs aligning the test image to the reference image, but most of the current image alignment methods are very time-consuming. In order to improve the efficiency of PCB inspection, we put forward an image alignment algorithm based on connected components matching, and design a procedure to detect defects and classify defects. Experimental results show that the proposed method achieves good results for real single layer, bare PCB inspection.
