PROCEDE DE FABRICATION DE CARTES A PUCEMETHOD FOR MANUFACTURING CHIP CARDS

MUNIES DE FILMS DE SURFACEPROVIDED WITH SURFACE FILMS

L'invention concerne un procédé de fabrication de cartes à puce munies de films de surface habituellement désignés sous le terme anglo-saxon "overlays". Les cartes à puce ont pour fonction d'identifier leur porteur et de sécuriser des données relatives, notamment, à des transactions électroniques réalisées par ledit porteur, ou alors, à des droits auxquels  The invention relates to a method of manufacturing smart cards provided with surface films usually designated by the English term "overlays". The function of smart cards is to identify their holder and to secure data relating, in particular, to electronic transactions carried out by said holder, or else, to rights to which

ce dernier peut prétendre.the latter can claim.

Ce sont des objets portatifs comportant, d'une part, un corps de carte et, d'autre part, un composant électronique à circuit intégré ou puce. Le corps de carte est plastique et se compose d'une ou plusieurs couches. Les couches externes dudit corps sont avantageusement revêtues de films de surface généralement transparents. Grâce à ces films, la carte a un bel aspect de brillance et les motifs imprimés du  These are portable objects comprising, on the one hand, a card body and, on the other hand, an electronic component with integrated circuit or chip. The card body is plastic and consists of one or more layers. The outer layers of said body are advantageously coated with generally transparent surface films. Thanks to these films, the card has a beautiful shine appearance and the printed patterns of the

Le composant électronique est une microplaquette de silicium sur laquelle est intégré un circuit qui définit des ensembles fonctionnels, tels que des ensembles mémoires, par exemple de type RAM, ROM ou EEPROM, ou, dans le cas de cartes dites à microprocesseurs, une unité  The electronic component is a silicon chip on which a circuit is integrated which defines functional assemblies, such as memory assemblies, for example of the RAM, ROM or EEPROM type, or, in the case of so-called microprocessor cards, a unit.

Le composant électronique est incorporé au corps de la carte. A cet effet, il est parfois préalablement intégré dans le module électronique  The electronic component is incorporated into the body of the card. To this end, it is sometimes previously integrated into the electronic module.

reporté dans une cavité du corps de carte.  transferred to a cavity in the card body.

Le composant électronique est par ailleurs susceptible d'être connecté aux bornes d'une antenne. Dans ce cas, la carte dispose d'un mode de fonctionnement sans contact et les données qu'elle échange avec le milieu extérieur sont susceptibles d'être transmises par couplage électromagnétique entre l'antenne de la carte et une antenne d'un lecteur associé. Dans le cas o le composant électronique n'est pas connecté aux bornes d'une antenne, la transmission des données  The electronic component is moreover capable of being connected to the terminals of an antenna. In this case, the card has a contactless operating mode and the data it exchanges with the outside environment are capable of being transmitted by electromagnetic coupling between the antenna of the card and the antenna of an associated reader. . In the case where the electronic component is not connected to the terminals of an antenna, the data transmission

s'effectue par contre nécessairement au moyen de contacts électriques.  on the other hand necessarily takes place by means of electrical contacts.

Pour la fabrication de cartes à puce, on connaît différent procédés.  Different processes are known for manufacturing smart cards.

Certains procédés proposent une colamination à chaud d'un ensemble comprenant les différentes couches destinées à former le corps de carte, les films de surface et la puce éventuellement intégrée au sein d'un module électronique et/ou connectée aux bornes d'une antenne. A cet effet, des forces de pression sont appliquées sur l'ensemble précité de manière que, à une température de l'ordre de  Some methods propose hot colamination of an assembly comprising the different layers intended to form the card body, the surface films and the chip possibly integrated within an electronic module and / or connected to the terminals of an antenna. To this end, pressure forces are applied to the above-mentioned assembly so that, at a temperature of the order of

C, les couches et films soient soudés.   C, the layers and films are welded.

Toutefois, ces procédés présentent certains inconvénients dus au fait que, au cours de la colamination, des bulles d'air sont parfois  However, these methods have certain disadvantages due to the fact that, during colamination, air bubbles are sometimes

emprisonnées entre les films de surface et les couches qu'ils recouvrent.  trapped between the surface films and the layers they cover.

Il en résulte certains défauts apparents à la surface du corps de carte et, notamment, la formation de cloques ou de zones de brillance contrastées. Considérant ce qui précède, un problème objectif que se propose de résoudre l'invention est d'éviter les défauts apparents à la surface des  This results in certain apparent defects on the surface of the card body and, in particular, the formation of blisters or areas of contrasting brightness. Considering the above, an objective problem which the invention proposes to solve is to avoid apparent defects on the surface of the

cartes comportant des films de surface.  cards with surface films.

La solution de l'invention à ce problème a pour objet un procédé de fabrication d'une carte comportant un corps de carte, ledit corps de carte comprenant une couche externe revêtue d'un film de surface caractérisé en ce qu'il comporte les étapes suivantes selon lesquelles on perce le film de surface de trous débouchants; on revêt la couche externe (4, 7) dudit film de surface percé de trous; et on colamine à chaud un ensemble comprenant ledit film de  The solution of the invention to this problem relates to a method of manufacturing a card comprising a card body, said card body comprising an outer layer coated with a surface film characterized in that it comprises the steps following which the surface film is drilled through holes; the outer layer (4, 7) is coated with said surface film pierced with holes; and a set comprising said film is hot-rolled

Ainsi, les bulles d'air emprisonnées entre la couche externe et le film de surface s'échappent par les trous. La carte fabriquée ne présente  Thus, the air bubbles trapped between the outer layer and the surface film escape through the holes. The manufactured card does not have

alors pas de défauts d'aspect dus auxdites bulles d'air.  then no appearance defects due to said air bubbles.

Avantageusement, les trous ont un diamètre moyen compris entre 0,2 et 1, 4 mm, notamment de l'ordre de 0,8 mm. Ainsi, les trous cicatrisent au cours de l'étape de colamination et la  Advantageously, the holes have an average diameter of between 0.2 and 1.4 mm, in particular of the order of 0.8 mm. Thus, the holes heal during the colamination step and the

carte finie ne présente pas de trous.  finished card has no holes.

Avantageusement, 0,1 à 2,5 % de la surface du film, préférentiellement de l'ordre de 0,5 % de cette surface, est percée de  Advantageously, 0.1 to 2.5% of the surface of the film, preferably of the order of 0.5% of this surface, is pierced with

1 0 trous.1 0 holes.

Ainsi, les retraits dus à la polymérisation du film et la cicatrisation ne sont pas suffisants pour occasionner des défauts d'aspect de la carte. L'invention sera mieux comprise à la lecture de l'exposé non limitatif des exemples de mise en oeuvre qui vont suivre, rédigés au regard des dessins ci-joints, dans lesquels: la figure lA montre, en coupe transversale, une carte à puce à contacts; la figure lB montre, en coupe transversale, une carte à puce sans contact; la figure 2, illustre, en coupe transversale, une étape de colamination d'une carte sans contact selon le procédé de l'invention; la figure 3A, montre, en coupe transversale et en vue agrandie, un film de surface destiné à la mise en oeuvre du procédé de l'invention; la figure 3B, montre, en coupe transversale et en vue agrandie, un film de surface d'une carte obtenue selon le procédé de l'invention; et la figure 4 montre, en coupe transversale, la manière dont sont fixés les films de surface dans l'ensemble destiné à une colamination  Thus, the shrinkages due to the polymerization of the film and the scarring are not sufficient to cause defects in the appearance of the card. The invention will be better understood on reading the nonlimiting description of the examples of implementation which will follow, written with reference to the attached drawings, in which: FIG. 1A shows, in cross section, a smart card with contacts; FIG. 1B shows, in cross section, a contactless smart card; FIG. 2 illustrates, in cross section, a step of colamination of a contactless card according to the method of the invention; FIG. 3A shows, in cross section and in enlarged view, a surface film intended for the implementation of the method of the invention; FIG. 3B shows, in cross section and in enlarged view, a surface film of a card obtained according to the method of the invention; and FIG. 4 shows, in cross section, the manner in which the surface films are fixed in the assembly intended for colamination

Les couches 4, 7 sont des couches thermoplastiques de PC d'une épaisseur de l'ordre de 150 Mm. La sous-couche 5 est une couche thermoplastique de PVC d'une épaisseur de l'ordre de 190 pm et la sous- couche 6 est une couche thermoplastique de PVC d'une épaisseur de l'ordre de 300 gm.

Pour la fabrication d'une carte selon le procédé de l'invention et, notamment, pour la fabrication de la carte sans contact montrée à la  For the manufacture of a card according to the method of the invention and, in particular, for the manufacture of the contactless card shown in the

figure lB, on procède en différentes étapes.  FIG. 1B, we proceed in different stages.

Dans une étape préalable, les films 8, 9 sont percés de trous 14 débouchants. Ainsi que cela est plus particulièrement montré à la figure  In a preliminary step, the films 8, 9 are pierced with through holes 14. As is more particularly shown in the figure

3A, ces trous 14 sont sensiblement cylindriques de révolution.  3A, these holes 14 are substantially cylindrical of revolution.

Néanmoins, ils peuvent avoir l'aspect de fentes ou plus généralement de découpes quelconques. Le diamètre moyen desdits trous 14, avantageusement compris entre 0,2 et 1,4 mm, est par exemple de l'ordre de 0,8 mm. L'entraxe moyen entre ces trous 14, avantageusement compris entre 2 et 20 mm, est par exemple de l'ordre de 10 mm. Aussi, 0, 1 à 2,5 %, notamment 0,5 % de la surface des films 8, 9 est percée de trous 14. On notera que les moyens destinés au perçage des trous 14 peuvent être constitués d'un rouleau muni d'aiguilles de diamètre voulu, ce rouleau étant passé sur des bandes de  However, they can have the appearance of slots or more generally of any cuts. The average diameter of said holes 14, advantageously between 0.2 and 1.4 mm, is for example of the order of 0.8 mm. The average spacing between these holes 14, advantageously between 2 and 20 mm, is for example of the order of 10 mm. Also, 0.1 to 2.5%, in particular 0.5% of the surface of the films 8, 9 is pierced with holes 14. It will be noted that the means intended for drilling the holes 14 may consist of a roller provided with needles of the desired diameter, this roller being passed over strips of

films pour un perçage à grande échelle.  films for large-scale drilling.

Dans une autre étape préalable, on reporte la puce 3 munie de protubérances 15 sur la sous-couche 5 à la surface de laquelle on a préalablement sérigraphie ou gravé l'antenne 11. La puce 3, fixée sur la sous-couche 5 est alors connectée électriquement aux bornes de ladite  In another preliminary step, the chip 3 provided with protuberances 15 is transferred to the sublayer 5 on the surface of which the antenna 11 has been screen-printed or engraved. The chip 3, fixed to the sublayer 5 is then electrically connected to the terminals of said

antenne 11.antenna 11.

Lesdites étapes préalables ayant été effectuées, on superpose la couche externe 4, la sous-couche 5 portant la puce 3, la sous-couche 6, la couche externe 7 et les films de surface 8, 9 de manière à former un ensemble superposé que l'on place entre des plateaux 16, 17 parallèles  Said preliminary steps having been carried out, the outer layer 4 is superimposed, the sublayer 5 carrying the chip 3, the sublayer 6, the outer layer 7 and the surface films 8, 9 so as to form a superimposed assembly that we place between plates 16, 17 parallel

d'un dispositif de pressage (figure 2).  a pressing device (Figure 2).

A cause, en particulier, de l'épaisseur de la puce 3, les couches 4, 5, 6, 7 et films 8, 9 de l'ensemble placé dans le dispositif de pressage ne sont pas strictement parallèles. Des poches d'air existent donc dans l'ensemble superposé et, en particulier, entre les films 8, 9 et les couches externes 4, 7 qui n'adhèrent pas auxdits films 8, 9 à ce stade  Because, in particular, of the thickness of the chip 3, the layers 4, 5, 6, 7 and films 8, 9 of the assembly placed in the pressing device are not strictly parallel. Air pockets therefore exist in the superimposed assembly and, in particular, between the films 8, 9 and the outer layers 4, 7 which do not adhere to said films 8, 9 at this stage

du procédé de l'invention.of the process of the invention.

Néanmoins, dans une étape de colamination au cours de laquelle les plateaux 16, 17 du dispositif de pressage sont rapprochés l'un de l'autre et amenés, par exemple dans un four, à une température de l'ordre de 120 C, les couches 4, 5, 6, 7 et films 8, 9 sont soudés les uns aux autres, les poches d'air se vidant par les trous 14 débouchants  However, in a colamination step during which the plates 16, 17 of the pressing device are brought close to each other and brought, for example in an oven, to a temperature of the order of 120 C, the layers 4, 5, 6, 7 and films 8, 9 are welded to each other, the air pockets emptying through the through holes 14

suffisamment larges pour permettre l'échappée de l'air.  wide enough to allow air to escape.

Sous l'effet de la pression et de la chaleur, les trous 14 cicatrisent, c'est-à-dire se rebouchent. Cette cicatrisation est permise du fait d'un diamètre suffisamment restreint des trous 14. La carte 1, alors obtenue après avoir été retirée du dispositif de  Under the effect of pressure and heat, the holes 14 heal, that is to say, fill up. This scarring is allowed because of a sufficiently small diameter of the holes 14. The card 1, then obtained after having been removed from the device

pressage, ne présente aucun défaut d'aspect.  pressing, has no appearance defect.

En pratique, pour la fabrication en série des cartes à puce, les ensembles colaminés ont des dimensions bien plus larges que celles des cartes et comprennent plusieurs puces 3 (voir figures 2 et 4). Ainsi, il est possible de fabriquer plusieurs cartes à la fois, après une étape  In practice, for the mass production of smart cards, the colaminated assemblies have much larger dimensions than those of the cards and comprise several chips 3 (see FIGS. 2 and 4). Thus, it is possible to make several cards at the same time, after a step

complémentaire de découpe des ensembles colaminés.  complementary cutting of colaminated assemblies.

A cet égard, il doit être noté que les films 8, 9, qui devaient antérieurement être tendus à la surface des ensembles de manière à minimiser la formation des poches d'air, ne sont pas nécessairement tendus dans la mise en oeuvre de l'invention. Il est par suite possible de recouvrir les couches à colaminer d'un unique film 8, 9 fixé, à la manière montrée à la figure 4, à une même extrémité de l'ensemble. Cet unique film 8, 9 couvre alors, de même qu'une couverture d'un livre,  In this regard, it should be noted that the films 8, 9, which previously had to be stretched over the surface of the assemblies so as to minimize the formation of air pockets, are not necessarily stretched in the implementation of the invention. It is therefore possible to cover the layers to be laminated with a single film 8, 9 fixed, as shown in Figure 4, at the same end of the assembly. This unique film 8, 9 then covers, like a book cover,

l'ensemble des couches 4, 5, 6, 7.the set of layers 4, 5, 6, 7.

Bien entendu, le procédé de l'invention, décrit ci-dessus au regard de la fabrication d'une carte sans contact, s'applique à la fabrication de cartes à contacts. En effet, des bulles d'air sont toujours présentes  Of course, the method of the invention, described above with regard to the manufacture of a contactless card, applies to the manufacture of contact cards. Indeed, air bubbles are always present

entre les couches et films avant colamination.  between layers and films before colamination.

Le procédé de l'invention s'applique par ailleurs à la fabrication de cartes par colamination dans le cas o les modules ou alors les puces ne sont pas présentes dans l'ensemble colaminé, mais sont reportés  The method of the invention also applies to the manufacture of cards by colamination in the case where the modules or else the chips are not present in the colaminated assembly, but are carried over

dans une étape ultérieure.in a later step.
