Definitions
- the present invention relates to the manufacture of smart cards comprising a communication interface with one exterior and at least one electronic component opening onto the surface.
- smart card is intended to mean any type of card which can operate with and / or without contact, that is to say that cards which can communicate with the outside by means of conventional standard contacts are envisaged, cards which can communicate with the outside via an antenna integrated in the card, or finally mixed cards which can communicate with the outside either via the antenna or via the conventional contacts.
- a communication interface is defined according to the type of operation of the smart card.
- the interface when the smart card is a contact-functioning card, the interface includes an integrated circuit module having access contacts intended to be flush with the surface of the card.
- the interface when the card operates without contact, the interface includes an integrated circuit module connected to an antenna and embedded in the card body.
- the interface when the card is a mixed card, the interface includes an antenna connected to an integrated circuit module having access contacts intended to be flush with the surface of the card.
- Chip cards are intended to carry out various operations such as, for example, banking operations, telephone communications, identification operations, debit operations or recharging of account units, and all kinds of operations which can be done either by inserting the card in a reader, or remotely by coupling electromagnetic (in principle of the inductive type) between a transmission-reception terminal and a card placed in the zone of action of this terminal.
- the installation of a display in a smart card can be useful in particular for making an electronic purse in order to allow viewing of the amount remaining in the purse, for example.
- Chip cards should preferably have standardized dimensions identical to those of conventional chip cards with contacts. This is obviously particularly essential for mixed cards and it is desirable for cards operating only in contactless mode.
- the usual ISO 7810 standard defines a card 85 mm long, 54 mm wide and 0.76 mm thick. The contacts are flush with well-defined positions on the surface of the card.
- the object of the invention is to propose a manufacturing method capable of best solving these problems of positioning, manufacturing precision, mechanical strength, and more generally of reliability, cost and production efficiency of the card.
- the invention provides a method of manufacturing a smart card comprising a communication interface with one exterior and at least one electronic component opening onto the surface, mainly characterized in that the electronic component is connected to the interface of communication by means of lead wires; the electronic assembly interface - electronic component is temporarily fixed against a first plastic plate; a second plastic plate is placed on the electronic interface - electronic component assembly, an opening being provided either on the first plate or on the second plate to serve as housing for the electronic component; and the two plates are secured by enclosing the interface and the electronic component.
- This process is simple and inexpensive. It makes it possible to reliably and precisely solve the problem of electrical connection between the electronic component (s) and the communication interface: the electrical connections are made before installation of the whole in a plastic card. The electronic component (s) and the communication interface are correctly placed in the card.
- the invention further provides another embodiment of a method for manufacturing a smart card comprising a communication interface with one exterior and at least one electronic component opening onto the surface.
- conductive tracks are produced on a flexible plastic sheet to form a printed circuit; the communication interface and the electronic component are fixed on the printed circuit obtained so that contact pads of the interface are connected to contact pads of the electronic component by means of the conductive tracks, - provisionally fixed the electronic printed circuit - interface - electronic component assembly against a first plastic plate; a second plastic plate is placed on the electronic printed circuit - interface - electronic component assembly, an opening being provided either on the first plate or on the second plate to serve as housing for the electronic component; and the two wafers are joined together by enclosing the electronic printed circuit - interface - electronic component assembly.

- the microcontroller 3 can also be connected to a battery 8 via flat conductive wires 9.
- FIG. 2 represents, in longitudinal section, the antenna-module-display-microcontroller-battery electronic assembly of FIG. 1, after soldering the various connections between the elements; however, the battery is not shown in this figure for the sake of clarity.
- This figure also shows a plastic plate 11, which may already be in the format of a smart card or which will be cut later in this format.
- the plastic material can be polyvinyl chloride (PVC) or polyethylene terephthalate (PET) or another plastic material.
- This plate 11 constitutes a part of the body of the smart card. It has one or more openings that can serve as housing for the module 2 and the display 4. In the example shown in FIG. 2, it has two openings 14 and 13 intended to receive the module 2 and the display 4 respectively. These openings 13 and 14 pass through the entire thickness of the wafer. The dimensions of each of the openings are adjusted in relation to the dimensions of the element that they are intended to receive.
- the position of the opening 14 reserved for the module 2, relative to the format of the wafer 11, corresponds to the standardized position of the contacts of a smart card.
- the rear face of the wafer 11 is coated with an adhesive sheet 12, the adhesive face of which is applied against the wafer.
- This sheet 12 covers the openings 13, 14 so that it constitutes a bottom for the housings made in the card by the openings 13 and 14. This bottom is adhesive.
- the module 2 comprises an integrated circuit 1 covered with a protective resin 15, the antenna wires 5 are shown in section as well as the interconnection wires 6 and 7.
- the display 4 is constituted by an assembly of two substrates 16, 17 between which are arranged liquid crystal or electrochromic or electrophoretic materials for example.
- the substrates 16 and 17 are provided with conductive tracks making it possible to generate the electro-optical effects of the active materials included between these two substrates. These conductive tracks are also connected to the electrical connection 6.
- the substrate 16 is shown longer than the substrate 17 so as to allow the electrical connection 6 with the microcontroller 3.
- the elements intended to reach the surface of the card that is to say, in the example shown, the module 2 and the display 4 are inserted respectively in the openings 14 and 13 and are bonded by the adhesive material of the sheet 12.
- FIG. 3 represents the smart card at this stage, with the wafers 11 and 19 on either side of the electronic assembly, and a binder resin 18 embedding the assembly between the wafers. 10
- the last operation (FIG. 4) consists in peeling off the adhesive sheet 12, then showing, on the surface of the chip card, the stripped contacts of the integrated circuit chip of the module 2 and the display screen of the display 4.
- FIG. 5 represents a finished smart card and manufactured according to an alternative embodiment.
- the display is placed on the back of the card.
- This example is limited to a single element on the front (module 2) and a single element on the back (display 4) of the card, but it is of course possible to insert several elements on the surface of the card, front as on the back of this one.
- the electronic assembly is placed on a first plastic plate 11 provided with a single opening 14 intended to receive the module 2.
- a second plastic plate 23 provided with a single opening 24 intended to receive the display 4 is then brought next to the electronic assembly.
- Another adhesive sheet 22 is glued to the second plate 23 to cover the opening 24 and to position the display, in the bottom of the housing created by the opening 24, at the exact dimension.
- the two plates 11 and 23 are laminated, hot or cold, in order to join them together by enclosing the electronic assembly.
- the last step consists, in this case, of peeling off the two adhesive sheets 12 and 22 to reveal, on the faces of the card, the contacts of the chip of module 2 on the front and the display screen of the display 4 on the back.
- FIG. 6 represents in perspective and in exploded form elements of constitution of a smart card comprising a communication interface (module 2 connected 11
- the electronic components are connected to a flexible and thin printed circuit 10.
- the printed circuit 10 can for example be produced on a sheet of plastic metallized by usual techniques and cut to the format of the card.
- An antenna which is not shown in FIG. 6 for reasons of clarity, as well as conductive tracks 6, 7, 9 making it possible to connect the various electronic components to each other, are for example produced by screen printing of conductive ink, by depositing metallizations on the plastic sheet, or by inlaying a copper wire in the plastic.
- the resin serves both as a material to give cohesion to the card body but it also allows the adhesion of the various plates 11, 19 with the printed circuit 10 and / or the electronic components.
- plastic sheet (s) thus constituting the heart of the card is not limiting.
- the different plastic sheets 20, plates 11, 19 and the printed circuit 10 can be assembled using the laminating technique. This can be obtained by fusing the plastic plates and sheets together; or preferably by coating the plastic sheets and the printed circuit with one or more types of adhesives, these adhesives being activated during the final lamination step. Adhesives which can be activated at temperatures and pressures compatible with the electronic components and the display present in the card body will preferably be chosen.
- a double-sided printed circuit 10 is produced comprising metallizations 6, 7, 9 on its two faces, and conductive vias 30 for connecting the metallizations on one face to the metallizations on the other face.
- An opening 24 is also provided on an external plate 23 for placing the display 4 there and an opening 14 on the other external plate 11 for placing the module 2.
- the adhesive sheets 12 and 22 are however not essential when using the core plastic sheet because the thickness dimensions of this sheet are well adjusted so that certain components can open onto the surface of the card. Adhesive sheets are necessary when using soft, thermosetting resin, to retain components on the surface by the adhesive sheet.
