Abstract
A device for dissipating heat for a surface mount component assembled onto a printed circuit board is made up by a metallic plate deposited on the rear of the substrate under the surface mount component. A thermal coupling device is made up by a small heat collecting plate provided on the front side of the substrate and the actual substrate. The heat collecting plate also performs an electro-magnetic shielding function and is advantageously constituted either by the shielding plate normally provided for this purpose or by an extension thereof.
