Abstract

A method for applying a thin coating to a flat side (front side) and edge surfaces of a two-dimensional formation of graphite foil, includes applying the coating material to the flat side (front side) to be coated by electrostatic powder spraying followed by a sintering cycle or melting cycle. During the spraying, the two-dimensional formation is electrically contacted on a limited area virtually in the middle of its rear side, facing away from the spraying direction, on a limited area at a distance of at least 5 mm from the edges. A method for heat dissipation in electronic equipment, is also provided.
