CA 2447860

The invention relates to a method for shielding an electric circuit created on a printed circuit board (1) comprising a number or components (2). According to said method, a first electrically insulating layer (3) is applied to the whole surface of the printed circuit board (1) and a second earthed, electrically conductive layer (4), which acts as a shield, is then applied to the whole surface of said first electrically insulating layer (3), in such a way that suitable recesses (5) corresponding to the number of components are configured. The invention also relates to a corresponding combination of a printed circuit board (1), on which at least one electric circuit comprising a number of components (2) is created and a first electrically insulating layer (3) with a second earthed layer (4), which covers the whole surface and acts as a shield.

L'invention concerne un procédé pour le blindage d'un circuit électrique réalisé sur une carte à circuits imprimés (1) et comprenant un certain nombre de composants (2). Selon l'invention, on dépose, sur la carte à circuits imprimés (1), une première couche (3) isolante électriquement et couvrant toute la surface, ainsi qu'une deuxième couche électroconductrice (4), à la masse, agissant comme blindage et couvrant toute la surface, des évidements (5) correspondant au nombre de composants (2) étant ménagés. L'invention concerne également une combinaison correspondante de carte à circuits imprimés (1) sur laquelle est réalisé au moins un circuit électrique constitué d'un certain nombre de composants (2) et qui présente une première couche (3) isolante électriquement, ainsi qu'une deuxième couche électroconductrice (4), à la masse, couvrant toute la surface et agissant comme blindage.
