Electric machine

An electric machine comprising

• a heat sink;
• an electronic module comprising
• a printed circuit board having a first conductive layer defining, at least partly, a first face, or top face, of the printed circuit board, a second face, or bottom face, of the printed circuit board, a plurality of vias which pass through the printed circuit board between the top face, in contact with the first conductive layer, and the bottom face,
• the electronic module comprising
• at least one electronic component soldered to the printed circuit board on the first conductive layer by its own base and disposed, at least partly, on top of at least a first part of the vias,
• a conductive mass, soldered to the printed circuit board in proximity to the electronic component and disposed, at least partly, on top of at least a second part of the vias, the conductive mass and the electronic component being in heat exchange relationship through a thermal and electrical connection,
• the second face of the printed circuit board being in heat exchange relationship with the heat sink, the electronic component and the conductive mass being in heat exchange relationship with the heat sink through the first conductive layer and at least the first and the second part of the vias.
