Joining of Glass

Laser Welding of glass requires special considerations due to the thermal, mechanical and optical material properties. Typically, glass is characterized by low thermal conductivity, moderate tensile strength, and high brittleness.

Micro-Joining of dissimilar Materials

Micro-joining of dissimilar materials for optoelectronic and biomedical applications is a challenging issue due to the differences in their mechanical, chemical, optical and thermal properties. The optoelectronic industry requires new assembling technologies that allow high integration, hermetic sealing and automated assembly. The medical device industry is looking for biocompatible materials and manufacturing processes that ensure long-lasting functionality and reliability. In cooperation with the Wayne State University in Detroit we investigate the challenges of packaging of biomedical devices.

Plastic Welding

Today, typical joining methods for plastic parts are screwing, clipping or force fitting, gluing and welding. Among the welding methods, laser welding has recently become an interesting alternative to conventional techniques due to the excellent joint appearance (hidden joints) the high weld quality. Laser welding provides liquid and air-tight joints and high repeatability.
