A method for making a contactless chip card of the type having an electronic module, and an antenna connected to the module, includes the following steps: producing, on a first support sheet, the antenna with connection terminals provided at its ends; producing an insulating bridge partly covering the antenna coils except for the connection terminals; depositing a drop of filling material on the insulating bridge; transferring the electronic module, with its connection pads being oriented towards the insulating bridge; and providing an electric connection between the module contact pads and the antenna connection terminals.

Method for making a contactless chip card

The invention concerns the production of contactless transmission chip card, and particularly mixed cards operating with or without contact. The method for the reliable and efficient setting of an integrated circuit module (M) and of an inductive transmission antenna (A), consists in producing the module providing connection ranges for the antenna, making an antenna with a flat coiled wire, and soldering the ends of said antenna on the module ranges, then making a plastic wafer ( ) provided with an opening, the bottom of this opening being closed by an adhesive film ( ). The module and the antenna are set against the wafer, and maintained by the adhesive material at the bottom of the housing. Another wafer ( ) is directly mounted on the assembly.
