Abstract

L'invention porte sur un micro blindé et sur le procédé de blindage connexe. Ce micro est destiné à servir dans un dispositif de communication mobile équipé d'une carte de circuits imprimés et d'un micro, notamment lorsque ledit dispositif est aussi muni d'une antenne montée tout près du micro. Le micro est logé dans un réceptacle offrant une protection électromagnétique (p. ex. une boîte de blindage) et muni d'un séparateur résilient (joint torique ou disque) monté sur le blindage. Le boîtier du dispositif est monté par dessus le séparateur et le blindage, alors que ce dernier est placé au dessus de la carte de circuits imprimés, le micro étant pris en sandwich entre le boîtier et la carte. En empilant ainsi les composants, le séparateur appuie sur le blindage de façon à pousser celui-ci contre la carte de circuits pour la mettre à la masse, le micro étant aussi branché à la carte de circuits. Ce dernier se trouve donc coincé entre la carte de circuits et le blindage qui l'isole de l'énergie électromagnétique diffusée par l'antenne avoisinante. La résilience du séparateur laisse un jeu suffisant pour l'empilage des composants.
