Abstract: Semiconductor Laser diode bars are high power products, used in places where small and efficient emitting light sources are needed. Primarily, these Lasers are being used as pumping sources for optical resonators of solid state Lasers or gas Lasers. In other fields of application the light is used in a direct way, for instance in medical devices or material processing. Finetech bonders are just as much at home in research & development as they are in production environment and are ideally suited for accurate Laser diode bar bonding. The entire assembly process includes the alignment and bonding on sub carriers as well as the bonding of those subassemblies onto special heatsinks. The following document describes the challenges associated with the assembly of Laser diode bars, common error cases and Finetech’s approach to present solutions for a successful process.
