Abstract
A system for detecting deposited metals on soldering points of an integrated circuit board substrate, a light source, a charge coupled device camera, and a computer. The camera captures an image of the substrate of a ball grid array integrated circuit board and converts the image into a digital image signal. The dot matrix image is transmitted to the computer for analysis by software to examine a conformity index between the image on the substrate to be detected and the image of a reference substrate, thereby providing an automatic detecting function.
