Thermal and Environmental Analysis Lab

IR-thermography on active power semiconductor

We offer thermal investigations of both - the materials and the systems. In order to be able to characterize thermal interface materials (TIM), a system was set up for determine heat conductivity and thermal resistance depending on the resistance relative to compression force. Infrared measurement techniques measure temperatures without any contact to detect errors in systems or components.
