Abstract
Abstract Integrated modules are disposed on a flexible printed circuitboard. The entire rear surface of each module is in contact with a common cooling plate and the individual contact pressure of the individual integrated modules against the cooling plate occurs by way of resilient elements respectively inserted between the printed circuitboard and the modules.
