ELECTRONIC DEVICE PROVIDED WITH AN INTEGRATED HEAT SPREADER

摘要

The invention relates to an electronic device provided with a heat spreader, in particular to plastic box-like devices comprising one or several stages of components. The inventive electronic device, for example a box-like, is provided with external connection pads (11) which are distributed on a connecting surface (22), comprises a heat-conductive plate (23) which is disposed in a parallel position with respect to said connecting surface and whose non-uniform structure, when the device is exposed to a given external temperature, makes it possible to carry out a controlled heat supply to each external connection pad according to the position thereof on the connecting surface. When the device is embodied in the form of a box comprising a support (20) in the form of a printed circuit, the conductive plate advantageously forms the internal layer thereof.
