For optimum design of electronics cooling solutions thermal performance and thermo-mechanical reliability have to be addressed right from the beginning and on an equal footing. This entails a comprehensive approach: Virtual prototyping by FE-simulations as well as experimental verification and testing focused a priori on materials, technology and failure-related issues. In this paper we present an approach based on this principle to design reliable thermal management solutions for high power chip modules. This approach is exemplified for a closed-loop micro-channel water cooling system, where the accent is put on flip-chip reverse side cooling. A numerical parametric study is carried out for an optimisation with respect to thermal performance and thermo-mechanical reliability, where the results concerning lifetime may also be extended to air-cooled systems.
