METHOD FOR PRODUCTION OF A CARD WITH A DOUBLE INTERFACE AND MICROCIRCUIT CARD OBTAINED THUS

摘要

The fabrication of a micro-circuit card in which a card body incorporates some contacts for connection to an electronic component and is provided with a cavity having a bottom and edged by steps for the contacts and includes a support film carrying contacts on an external surface and contacts on an internal surface and a micro-circuit is connected to the internal contacts. - After the micro-circuit is connected to the internal contacts the following steps are carried out: - (a) an adhesive, flexible, anisotropic conducting film is applied on the periphery of the internal surface; - (b) a resin of greater rigidity than the adhesive film is deposited in the bottom of the cavity; - (c) the module is inserted into the cavity such that the adhesive is situated opposite the periphery of the stepped structure of the cavity; - (d) the adhesive is activated thermally under pressure and the resin polymerized. - An INDEPENDENT CLAIM is also included for a micro-circuit card fabricated by this method.
