A method of fabricating an electronic power module by additive manufacturing, the electronic module including a substrate having an electrically insulating plate presenting opposite first and second faces, with a first metal layer arranged directly on the first face of the insulating plate, and a second metal layer arranged directly on the second face of the insulating plate. At least one of the metal layers is made by a step of depositing a thin layer of copper and a step of annealing the metal layer, and the method further includes a step of forming at least one thermomechanical transition layer on at least one of the first and second metal layers, the at least one thermomechanical transition layer including a material presenting a coefficient of thermal expansion that is less than that of the metal of the metal layer.

Method of fabricating an electronic power module by additive manufacturing, and associated substrate and module

Power electronic module comprising a plurality of semiconductor power electronic components electrically connected to an electrical support, and a cooling device in thermal contact with each component, each component being present between the electrical support and the cooling device and being mounted on the electrical support via at least one electrically conductive spring element.
