Abstract: The method comprises the steps of 1) producing first and second blanks (EB1, EB2) by laminating insulating and conductive inner layers (PP, CP, E1) on copper plates forming a base (MB1, MB2), at least one electronic chip (MT, MD) being sandwiched between the blanks, said blanks being produced such that their upper lamination surfaces have matching profiles, 2) stacking and fitting the blanks via their matching profiles, and 3) press-fitting the blanks to form a laminated sub-assembly for an integrated power electronics device. The method uses IMS-type techniques.

Abstract: The method comprises: 1) producing a preform (EB1) integrating at least one electronic chip (MT, MD) included between insulating and/or conductive laminated internal layers; 2) mechanically securing metal bus-bar segments (BB1, BB2, BB3) at given spaced-apart positions on opposing upper and lower faces of the preform, using dielectric portions of resin prepreg (PP1, PP2, PP3); and 3) for each of the upper and lower opposing faces, electrodepositing a metal layer (ME) in order to interconnect bus-bar segments secured to the face in question and an electrode of the electronic chip, thereby forming an electronic power circuit comprising bus-bars forming heat sinks (BBH, BBL).

Abstract: The invention relates to a cooling device for a printed circuit board, comprising a printed circuit board equipped with at least one face or first face and at least one heat sink (9) brazed to said at least one face of the printed circuit, in which said at least one heat sink (9) can be disposed in a flow of coolant. The invention is suitable for motor vehicles.

Abstract: The invention relates to a ventilation device (1) for a ventilation unit of a motor vehicle passenger compartment, comprising: an impeller (4) that generates an air flow (11, 12) and can be driven by an electric motor; and a printed circuit board (15) having secured thereto at least one electronic component (19) that can release calories. The printed circuit board (15) comprises at least one through-hole (18) provided in a part (21) of the printed circuit board (15). The ventilation device (1) is configured such that the air flow (11, 12) generated by the impeller (4) moves along said part (21) of the printed circuit board (15).

Abstract: The present invention concerns a thermal management and connection device for a battery module (1) consisting of cells (3) juxtaposed in parallel and connected to each other in series, each cell (3) comprising a positive terminal (4) and a negative terminal (4), said battery module (1) further comprising a heat exchange plate (10) comprising an inlet (12A) and an outlet (12B) for a heat-transfer fluid, positioned between the terminals (4), and a non-conductive connection plate (20) comprising holes (22) for the passage of the terminals (4) and means (6) for connecting said terminals (4) two by two with each other, the connection plate (20) being a printed circuit comprising conductor tracks (60).
