The utility model relates to
camera module manufacturing technical field discloses a novel COB photosensitive
assembly structure based on
laser welding, including photosensitive element body, the right side of photosensitive element body is provided with PCB circuit board, the upper of photosensitive element body is provided with transparent substrate. With
laser welding photosensitive element body and PCB circuit board, replace traditional gold wire
welding, save DA
machine platform, through accurate control
laser parameter, realize
low melting point tin cream's quick melting and solidification, are used for welding photosensitive element body and PCB circuit board, realize electric connection, and avoid to cause
thermal damage to photosensitive element body and PCB circuit board, need not expensive DA
machine platform, utilize existing
glass material and laser equipment, reduce equipment investment, process simplification, be suitable for more manufacturer production COB module, laser
welding process precision is high, fast, promote production efficiency, transparent substrate reusable conductive
circuit design, reduce material waste.
