Abstract
A laser-assisted soldering apparatus includes a solder jetting section and a laser coupling unit. The solder jetting section includes a jetting nozzle and a solder body holding capillary adapted to hold a solder body that is being liquefied by a laser beam. The laser coupling unit includes an optical window, a laser entry, a laser passage, a fastening section, and a laser exit. The laser passage extends from the laser entry to the laser exit and is aligned with the solder body holding capillary. The optical window is transparent to the laser beam. The fastening section is fastened to the solder jetting section. A first pressure gas feeding passage merges into the laser passage between the optical window and the fastening section. The solder jetting section includes a second pressure gas feeding passage that merges into the solder body holding capillary between the laser exit and the jetting nozzle.
