Abstract:
A manufacturing process of a hybrid contact-contactless smart card with an antenna support made of fibrous material such as the paper, including the following steps:a manufacturing process of the antenna consisting in screen printing turns of electrically conductive polymer ink on a support made of fibrous materials and to subject said support to a heat treatment in order to bake said ink, a step for laminating the card body onto the antenna support consisting in welding on each side of said support at least two sheets of plastic material, forming the card bodies, by hot press molding, a cavity milling step consisting in piercing, in one of the card bodies, a cavity for housing the module comprised of the chip and the double-sided circuit, said cavity including a smaller internal portion which receives the chip and a larger external portion for receiving the double-sided circuit, said cavity including a smaller internal portion which receives the chip and a larger external portion for receiving the double-sided circuit, said cavity being dug into the card body which is opposite the side of the support featuring the electrically conductive screen printed ink which forms the antenna, and the milling operation enabling the connection pads to be removed from the chip, and a module insertion step consisting in using a glue enabling said module to be secured and a glue containing silver for connecting said module to said connectors, and to position said module in the cavity provided to this end.
