The invention relates to a process for manufacturing a roll of flexible carrier bearing electronic components. This process includes a step consisting in adding, to this flexible carrier, electronic components, themselves manufactured from a roll of flexible initial substrate. For example, the electronic components may be manufactured on an initial substrate having a width allowing advantage to be taken of densification of the manufacture of the components on this initial substrate. Subsequently, the singulated electronic components are added to the flexible carrier, allowing, for example, packaging that is more suitable, than possible with the initial substrate, to a use of the electronic components, notably when the latter must be integrated into a chip-card. Thus, for example, the flexible carrier may be, or include, an adhesive, which may or may not be conductive, and which is used to fasten, and optionally connect, each electronic component to a chip-card.

The invention relates to a chip card designed to communicate data in a contactless mode with a card reader operating at a reading frequency. The resonance frequency of the chip card may change according to the capacitance of the chip used in the contactless mode of the chip card. In order to be able to use various chips without changing the booster antenna design, the card antenna circuit is provided with a capacitance element such that the chip card including the card antenna circuit and the chip module has two different resonance frequencies, one of which being equal to, or lower than, the reading frequency and the other being equal to, or greater, than the reading frequency. This create a broadband wherein the reading frequency falls.

When forming layer stacks in the presence of solder material, uncontrolled flow of the solder material at the interface of two different layers of the layer stack may significantly be mitigated by providing an area of increased pressure in the material of the overlaying foil layer. For example, the area of increased pressure may be generated during the lamination process by providing a pressure inducing structure, for instance on the underlying foil layer, which laterally surrounds the solder material and therefore, in combination with the material of the overlying foil layer, reliably confines the solder material.

A chip card manufacturing method. A module includes a substrate supporting contacts on one surface and conductive paths and a chip on another; and an antenna on a holder, the antenna including a contact pad for respectively connecting to each of the ends thereof. A solder drop is placed on each of the contact pads of the antenna. The holder of the antenna is inserted between plastic layers. A cavity is provided, in which the module can be accommodated and the solder drops remain accessible. The height of the solder drops before heating is suitable for projecting into the cavity. A module is placed in each cavity. The areas of the module that are located on the solder drops are heated to melt the solder and to solder the contact pads of the antenna to conductive paths of the 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.
