HEATPACK project aims to develop and validate critical technology building blocks for enabling transformative packages for space applications with very low thermal resistance. This is to fully exploit the potential of wide-bandgap technologies which are now being considered as critical in numerous sectors and for space applications in particular, as enhanced thermal management solutions beyond state-of-the-art need to be provided. Benefits will range from improved performance to increased components reliability and lifetime. HEATPACK concepts for achieving high power / high thermal efficiency packages include: - Diamond based composite materials with a thermal conductivity >600W/m.K to be used as baseplate or insert - Silver sintering based Thermal Interface Material (TIM) for components assembly - TIM for package to structure assembly with both electrical and thermal enhanced properties (in excess of 10W/m.K) - Innovative cooling solutions with strategic implementation possibilities (baseplate, lid, structure…) Using these technologies, two different modules implementing Gallium Nitride (GaN) components will be developed: -A power supply switching module based on a multilayer ceramic substrate -A L-band High Power Amplifier based on a single hermetic micro package, delivering up to 400W CW output power The main application targeted is the Galileo Second Generation satellite program since thermal management of the GaN HEMT based Solid State Power Amplifier and Electronic Power Conditioner sections currently provide a roadblock due to the very high power levels involved. Other needs are linked to power conditioning notably for digital transparent processor targeting very high throughput satellite for telecommunication. To secure a fully European supply chain for high power components thermal management, the technologies developed will reach a TRL of 7, demonstrating commercial viable solutions providing reliability levels compliant with space environments.
