Power electronics, place ever-greater demands on thermal management. The heat generated during operation not only affects functionality but can also significantly reduce the lifespan of electronic assemblies. Lackwerke Peters has long been dedicated to developing innovative material solutions to meet these thermal challenges. One such solution are the screen-printable heatsink pastes, thermal interface materials that combine high thermal conductivity with process reliability, application flexibility as well as cost reduction. The processing and performance of the latest generation of these pastes is introduced and discussed.
