Applications of Galvanometer Laser Scanning Soldering

I. Working Principle of Galvanometer Laser Scanning Soldering Systems

Galvanometer laser scanning soldering systems utilize galvanometer scanning technology to reflect and convert a laser beam into a rapidly scanning laser spot through mirrors. The laser spot precisely scans across circuit boards, achieving accurate welding at targeted locations via high-precision motion control. This process enables high-speed, ultra-precise soldering operations.
