Many applications of these technologies are found in the (opto) electronics environment. Applications often require a high temperature resistance, chemical inertness and vacuum leak free products. Louwers uses various bonding technologies like melting, soldering, thermal compression and anodic bonding. The melting of glass and metal components (or other materials) is most frequently used. Louwers has the engineering knowledge to combine various materials in the best way herewith optimizing the different coefficients of expansion, viscosity differences and differences in 'actual joining' temperatures.

Glass Types Metal Types Ceramic Types

In order to comply with the severe application requirements it is key to find a match between the materials to be used in the sealing or bonding process.
Louwers has the experience, the knowledge and the engineers to establish the right fit.
