Title: (DE) ABGESCHIRMTE ELEKTRISCHE EINRICHTUNG UND HERSTELLUNGSPROZESS DAFÜR
(EN) A SCREENED ELECTRICAL DEVICE AND A PROCESS FOR MANUFACTURING THE SAME
(FR) DISPOSITIF ELECTRIQUE BLINDE ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN) A protected electrical device having at least one electrical sub-assembly (1) to be protected comprises on at least one (11) of upper and lower surfaces (11, 12), at least a screening layer (2) against the electromagnetic (EM) and radiofrequency (RF) fields emitted by the electrical sub-assembly (1). The screening layer (2) comprises at least a first layer made of soft magnetic material with a high relative permeability (µr) larger than 500. The screening layer (2) is placed on substantially the whole surface of said at least one (11) of the upper and lower surfaces (11, 12), except on predetermined regions (1a) of limited area, the electrical connections (8, 9) with external devices being located on at least some of the predetermined regions of limited area.
(FR) La présente invention a trait à un dispositif électrique protégé comportant au moins un sous-ensemble électrique (1) destiné à être protégé comprenant au moins sur une (11) parmi des surfaces supérieure et inférieure (11, 12), au moins une couche de blindage (2) contre les champs électromagnétiques (EM) et radiofréquence (RF) émis par le sous-ensemble électrique (1). La couche de blindage (2) comporte au moins une première couche réalisée en un matériau magnétique doux avec une perméabilité relative élevée ($g(m)r) supérieure à 500. La couche de blindage (2) est disposée sensiblement sur toute la surface de ladite au moins une (11) des surfaces supérieure et inférieure (11, 12), sauf sur des zones prédéterminées (1a) de surface limitée, les connexions électriques (8, 9) avec les dispositifs externes se trouvant au moins sur certaines des zones prédéterminées de la surface limitée.
