Capabilities & Technologies
Our thick-film circuits or hybrid circuits are based on AL2O3 (aluminum oxide), AIN (aluminum nitride) and on stainless steel substrates.
The areas of application have expanded again and again due to the enormous reliability.
We have an extensive service portfolio for you with different process integration.
From the technology development of your thick-film hybrid circuit to the production of complex hybrid modules, assemblies and OEM products.
