Abstract: A laser soldering system using dynamic light spot and a method thereof are provided. A laser module is controlled to radiate toward multi-lens to form a light spot on a soldering target for soldering, and a lens distance between the multi-lens is adjusted to adjust a light spot size. The disclosure may provide multiple heating densities respectively adequate to different soldering status via adjusting the light spot size when using same laser power, so as to improve the soldering quality.
