Abstract:
A computerized system for detecting the presence of deposited metals on soldering points of a substrate of an integrated circuit board, the detecting system comprising:a light source adapted to positioned above the substrate to provide illumination of the soldering points;an image receiving element adapted to be mounted above the substrate for receiving light beams reflected from the substrate as a result of said illuminations and outputting a digital image signal of an image of the substrate formed by the beams; andan image processing device including an input and an output for signals, a memory storing a predetermined reference image of an acceptable substrate, and a central processing unit, the image processing device receiving the digital image signal from the image receiving element, the central processing unit having a program for comparing the image of the substrate and the reference image stored in the memory to determine whether the substrate to be detected is acceptable, and the result of the determination being outputted by the output.
