SMT(Surface Mounted Technology) is one of the most commonly used technologies in electronic assembly industry. what are the applications of machine vision used in SMT industry? Machine vision is mainly used for positioning and quality inspection of SMT production line, including printing machine steel mesh and PCB alignment, solder paste 3D scanning, placement machine components positioning, post printing AOI, post SMT AOI, post furnace AOI, etc.

Applications:

Dispensing detection, component positive and negative pole judgment, component assembly positioning, PCB solder reinspection (more tin, less tin, etc.), OCR(optical character recognition), 2D code recognition on the surface and so on.
