Abstract

Un ensemble circuit blindé (10) comprend un substrat (15) et un blindage conformable (25). Le substrat (15) renferme des circuits électriques contenant des composants électriques (13). Le blindage conformable (25) comprend un matériau conformable comportant une couche conductrice (30) et une couche isolante (26). Le blindage conformable (25) est placé sur les composants électriques (13) et sur au moins une partie du substrat (15). Ledit blindage (25) est sensiblement ajusté autour de chacun des composants électriques (13) afin de blinder ces derniers un par un.
