Thin Film Processing

Our Service

Thin films are used for electronic applications, for wear and corrosion protection as well as for optical and structural applications. The functionalization of these layers by means of laser radiation enable the realization of ressource- and energy efficient production processes with minimal thermal load for the work part. The local selectivity as well as the inline-capabilty open new possibilities for the layout of new products and production processes.

Our service portfolio includes feasibility studies for customer-specific problems, integration of laser functionalization into the production process as well as consulting for the concept of processes and plants.

Brochures

Our brochures offer a quick view onto the service portfolio "Thin Film Processing". Find more detailed information in the "project results" tab below.
