METHOD FOR MANUFACTURING A DEVICE FOR BURNING OFF THERMAL ENERGY PRODUCED BY ELECTRONIC COMPONENTS EMBEDDED IN A PRINTED CIRCUIT CARD, AND RESULTING DEVICE

摘要

The invention concerns a method for manufacturing a device for dissipating thermal energy produced by electric components (A, B, C) embedded in a printed circuit card (1), consisting in depositing on the card (1) a first level (10) of a first material thermally conductive and electrically insulating for covering at least the connection pins (4) of the electronic components (A, B, C) to be cooled, and in putting this first film (10) in contact with a metal drain (12) connected to a thermal mass for draining the calories outwards. The invention is characterised in that the method consists in producing the drain (12) in the form of a flexible and porous metal structure, and in depositing on the drain (12) a second level of a second material which adheres to the first level (10) through the pores of the drain (12) for maintaining it on the card (1).
