<p>The invention pertains to a device for protecting an electronic printed circuit board, said electrical printed circuit board comprising at least two layers. According to the invention, said device comprises: - on a layer, at least one conductive part uniformly spread on an insulator layer, the entirety comprising the conductive part and the insulator layer forming a capacitive support presenting a uniform electrical field, said capacitive support being placed sensibly on the whole surface of one of the layers of the multi-layered electronic printed circuit board, said capacitive support being configured to deliver a reference capacitance; - a capacitive measurement microprocessor detecting a variation in capacitance; - means for transmitting a piece of information representing said variation in capacitance when an absolute value of a difference between said measured capacitance and said reference capacitance exceeds a predetermined threshold.</p> |
