The invention concerns a method for producing a flexible circuit for a chip card module. The invention consists of using conductive pads located on the same face of the module as the contacts intended to establish a connection with a card reader, in order to produce an electrical connection between an antenna and an electronic chip. The connections with conductive pads are located partly inside an encapsulation area and partly outside said encapsulation area and respectively to either side of same. The invention also relates to a flexible circuit for implementing this method.

Method for producing a circuit for a chip card module and circuit for a chip card module

The invention concerns a method for producing a printed circuit for a chip card module. This method involves producing two layers of electrically conductive material insulated from each other by a layer of insulating material, connection holes extending through the layer of insulating material and blocked by one of the layers of electrically conductive material, an area free of conductive material being provided in the other layer of electrically conductive material around the connection holes. The invention also concerns a printed circuit for a chip card produced using this method and a chip card module including such a printed circuit.
