Device having an electronic circuit mounted on a flexible carrier, protected against electrostatic discharges, and flexible card comprising this device

Abstract

Abstract Translated from French Le support du circuit (1) comporte au moins une piste conductrice (2) à laquelle une face supérieure dudit circuit est reliée par au moins un fil conducteur (5), le montage solidaire du circuit sur le support étant obtenu d'une part par solidarisation, au moyen d'une colle conductrice (4) d'une face inférieure du circuit électronique et du support souple et d'autre part par adjonction autour du circuit d'une résine (6), qui n'enrobe aucun fil conducteur, ledit dispositif étant revêtu extérieurement d'un vernis de protection (7). Selon l'invention, ladite colle conductrice (4), ladite résine (6) et ledit vernis de protection (7) contiennent quelques % en poids ou en volume d'un agent antistatique. Application aux cartes à mémoire. The circuit support (1) comprises at least one conductive track (2) to which an upper face of said circuit is connected by at least one conductive wire (5), the integral mounting of the circuit on the support being obtained on the one hand by joining, by means of a conductive adhesive (4) of a lower face of the electronic circuit and the flexible support and on the other hand by adding around the circuit a resin (6), which does not coat any conductive wire, said device being coated externally with a protective varnish (7). According to the invention, said conductive adhesive (4), said resin (6) and said protective varnish (7) contain a few% by weight or by volume of an antistatic agent. Application to memory cards.
