Abstract

Procédé de fabrication d'un circuit (1) multicouche de distribution de courant électrique comprenant la fabrication d'une succession de plaques (2) conductrices destinées à être empilées, la mise en place d'une couche (3) isolante électriquement entre les plaques conductrices que l'on empile, ces dites plaques conductrices présentant des zones (5) de contacts destinées à établir une connexion avec un composant ce procédé étant caractérisé en ce que localement au droit des zones de contact on projette dynamiquement à vitesse supersonique et par gaz sous pression et au travers d'une tuyère convergente divergente sur ces zones de contact une poudre conductrice dont les particules de ladite poudre vont lors de l'impact se déformer plastiquement, s'agglomérer et s'incruster dans la surface, au niveau de la zone de contact, et créer ainsi une couche conductrice électrique et protectrice vis-à-vis de l'atmosphère ambiante.
