SUPPORT FOR ELECTRONIC POWER COMPONENTS, POWER MODULE PROVIDED WITH SUCH A SUPPORT, AND CORRESPONDING PRODUCTION METHOD

摘要

This substrate for power electronic components comprises a colaminated multilayer composite material containing at least one internal layer (8) made of a material having a thermal expansion coefficient chosen depending on the expansion coefficient of said components, and external layers (6, 7) made of a thermally conductive material covering on either side said internal layer and connected together by wells (P) made of a thermally conductive material, said wells being arranged in the internal layer. Each interior layer forms an insert localized in a zone for mounting the components so that the external layers extend laterally beyond the insert.
