Abstract

L'invention concerne un procédé de fabrication d'un ensemble d'au moins un dissipateur thermique (1) et d'une carte (2) de circuit imprimé sur laquelle est solidarisé au moins un module de puissance (3), le procédé comprenant une étape d'insertion au moins partielle du module de puissance (3) dans une cavité (5) du dissipateur (1) avec une couche de pâte thermique (4) intercalée au moins localement entre le module de puissance (3) préalablement solidarisé ou non avec la carte (2) et le dissipateur (1). Préalablement à l'insertion au moins partielle du module de puissance (3) dans la cavité (5), la cavité (5) est remplie d'une couche de pâte thermique (4) suffisante pour qu'une portion du module de puissance (3) insérée dans la cavité (5) soit entièrement enrobée dans la pâte thermique (4), la pâte thermique (4) et la portion enrobée du module de puissance (3) occupant une totalité de la cavité (5).
