La présente invention concerne un module à circuit intégré et une carte àThe present invention relates to an integrated circuit module and a card

diaire de plages de connexion externe de la carte, soit par une liaison sans contact par couplage magnétique, radio ou optique. Un module à circuit intégré comprend généralement un film support ayant une première face portant le circuit intégré et des plages de connexion interne, et une seconde face portant des plages de connexion externe s'étendant jusqu'au pourtour de la seconde face, les plages de connexion interne et externe étant raccordées au circuit intégré. Ce module est destiné à être fixé dans une carte à connexion mixte comprenant un corps de carte dans lequel est noyée une antenne. Le module à circuit intégré est collé dans une cavité du corps de carte de façon que les plages de connexion interne s'étendent à l'aplomb de bornes  diary of external connection areas of the card, either by a contactless link by magnetic, radio or optical coupling. An integrated circuit module generally comprises a support film having a first face carrying the integrated circuit and internal connection pads, and a second face carrying external connection pads extending up to the periphery of the second face, the pads of internal and external connection being connected to the integrated circuit. This module is intended to be fixed in a card with mixed connection comprising a card body in which an antenna is embedded. The integrated circuit module is glued into a cavity of the card body so that the internal connection pads extend directly above the terminals.

dées aux bornes de l'antenne par une colle conductrice reçue dans des perçages s'étendant dans le corps de carte à l'aplomb des bornes de l'antenne et débouchant dans la cavité. La mise en place du module dans la cavité du corps de carte est effectuée en pressant celui- ci dans la cavité après le dépôt de la colle conductrice dans les perçages du corps de carte. Pour que le contact entre la colle conductrice et chaque plage de connexion interne soit suffisant pour permettre une liaison électrique efficace entre les plages de connexion interne et les bornes de l'antenne, il est en général déposé une quantité de colle telle que de la colle déborde du percage. Il en résulte que lors du collage, la colle en excès est chassée de la cavité du fait de la pression exercée sur le module et remonte entre les bords de la cavité et le bord du film support. La  dees at the terminals of the antenna by a conductive adhesive received in holes extending in the card body directly above the terminals of the antenna and opening into the cavity. The module is placed in the cavity of the card body by pressing it into the cavity after the conductive adhesive has been deposited in the holes in the card body. To ensure that contact between the conductive adhesive and each internal connection pad is sufficient to allow an efficient electrical connection between the internal connection pads and the antenna terminals, a quantity of adhesive is generally deposited, such as adhesive overflows from the hole. As a result, during gluing, the excess glue is expelled from the cavity due to the pressure exerted on the module and rises between the edges of the cavity and the edge of the support film. The

colle risque alors de venir établir une liaison de court-  glue then risks coming to establish a short-

Un but de l'invention est de fournir un moyen  An object of the invention is to provide a means

En vue de la réalisation de ce but, on prévoit, selon l'invention un module à circuit intégré comprenant un film support ayant une première face portant le circuit intégré et des plages de connexion interne et une seconde face portant des plages de connexion externe, les plages de connexion interne et les plages de connexion externe étant raccordées au circuit intégré, la seconde face du film support comprenant au moins une zone périphérique isolée électriquement du circuit intégré et s'étendant en regard  With a view to achieving this goal, an integrated circuit module is provided according to the invention comprising a support film having a first face carrying the integrated circuit and internal connection pads and a second face carrying external connection pads, the internal connection pads and the external connection pads being connected to the integrated circuit, the second face of the support film comprising at least one peripheral zone electrically isolated from the integrated circuit and extending opposite

d'au moins une des plages de connexion interne.  at least one of the internal connection areas.

Ainsi, s'il se produit une remontée de colle conductrice lors de la fixation du module à circuit intégré dans le corps de la carte, la colle conductrice n'atteint qu'une zone de la seconde face du film support isolée électriquement du circuit intégré. Le risque de formation  Thus, if there is a rise in conductive adhesive when the integrated circuit module is fixed in the body of the card, the conductive adhesive only reaches an area on the second face of the support film electrically isolated from the integrated circuit. . The risk of formation

d'un court-circuit est donc limité.  short circuit is therefore limited.

De préférence la zone périphérique comporte une couche métallique de même épaisseur que les plages de  Preferably the peripheral zone comprises a metallic layer of the same thickness as the ranges of

Les plages de connexion externe sont en général réalisées par dépôt d'une feuille conductrice sur la seconde face du film support et attaque acide de cette feuille pour délimiter les différentes plages de connexion externe. Dans cette réalisation, la zone périphérique est découpée à partir de la feuille conductrice initiale. La fabrication du module est donc simple et l'aménagement de zones périphériques isolées électriquement du circuit  The external connection pads are generally produced by depositing a conductive sheet on the second face of the support film and acid etching of this sheet to delimit the various external connection pads. In this embodiment, the peripheral zone is cut from the initial conductive sheet. The manufacturing of the module is therefore simple and the arrangement of peripheral zones electrically isolated from the circuit

Avantageusement, au moins une des plages de connexion interne comprend une cavité. La cavité peut alors  Advantageously, at least one of the internal connection pads comprises a cavity. The cavity can then

Avantageusement alors, la cavité est en forme de spirale. On positionnera préférentiellement la cavité pour qu'elle entoure la zone de la plage de connexion interne destinée à être en contact avec la colle. On assure ainsi tout à la fois un bon contact avec les bornes d'antenne et la réalisation d'un volume de réserve suffisant pour  Advantageously then, the cavity is in the form of a spiral. The cavity will preferably be positioned so that it surrounds the area of the internal connection area intended to be in contact with the adhesive. This ensures both good contact with the antenna terminals and the creation of a reserve volume sufficient to

recevoir l'excédent de colle.receive the excess glue.

Il sera fait référence aux dessins annexés, parmi lesquels: - la figure 1 est une vue de dessus du module à circuit intégré selon l'invention, du côté des plages de connexion externe, - la figure 2 est une vue de dessous de ce module à circuit intégré, - la figure 3 est une vue en coupe transversale  follows a particular non-limiting embodiment of the invention. Reference will be made to the accompanying drawings, in which: - Figure 1 is a top view of the integrated circuit module according to the invention, from the side of the external connection pads, - Figure 2 is a bottom view of this module with integrated circuit, - Figure 3 is a cross-sectional view

d'une carte à connexion mixte selon l'invention.  of a mixed connection card according to the invention.

En référence aux figures, le module à circuit intégré selon l'invention, généralement désigné en 1, comprend un film support 2. Le film support 2 a une première face 2.1 portant un circuit intégré 3 et deux plages de connexion interne 4, et une seconde face 2.2, opposée à la première face 2.1, portant une pluralité de plages de connexion externe 5. Le circuit intégré 3 est relié de façon connue en soi aux plages de connexion interne 4 et aux plages de connexion externe 5 par des conducteurs 6, et est noyé dans une goutte de résine 7  With reference to the figures, the integrated circuit module according to the invention, generally designated at 1, comprises a support film 2. The support film 2 has a first face 2.1 carrying an integrated circuit 3 and two internal connection pads 4, and a second face 2.2, opposite to the first face 2.1, carrying a plurality of external connection pads 5. The integrated circuit 3 is connected in a manner known per se to the internal connection pads 4 and to the external connection pads 5 by conductors 6, and is drowned in a drop of resin 7

entourant également les conducteurs 6.  also surrounding the conductors 6.

Conformément à l'invention, deux bandes réalisées à partir de la même feuille conductrice que les plages de connexion externe 5 mais séparées de celles-ci s'étendent  According to the invention, two strips made from the same conductive sheet as the external connection pads 5 but separated from them extend

sur la périphérie de la seconde face 2.2 du film support.  on the periphery of the second face 2.2 of the support film.

Chaque bande 8 s'étend en regard d'une plage de connexion interne 4. Les bandes 8 sont espacées des plages de connexion externe 5 et isolées électriquement du circuit  Each strip 8 extends opposite an internal connection pad 4. The strips 8 are spaced from the external connection pads 5 and electrically isolated from the circuit

intégré.integrated.

Chaque plage de connexion interne 4 comprend une  Each internal connection pad 4 includes a

cavité 9 en forme de spirale.cavity 9 in the form of a spiral.

En référence plus particulièrement à la figure 3, la carte à connexion mixte selon l'invention comprend un corps de carte dans lequel est noyée une antenne 11. Le corps de carte 10 comprend une cavité 12 pour recevoir le  Referring more particularly to FIG. 3, the card with mixed connection according to the invention comprises a card body in which an antenna 11 is embedded. The card body 10 comprises a cavity 12 for receiving the

module 1 décrit précédemment.module 1 described above.

Des perçages 13 s'étendent à l'aplomb des bornes de l'antenne 11 pour déboucher dans la cavité 12. Les  Holes 13 extend vertically above the terminals of the antenna 11 to open into the cavity 12. The

perçages 13 contiennent de la colle conductrice 14.  holes 13 contain conductive adhesive 14.

Le module 1 est fixé avec de la colle 15 de type cyanoacrylate dans la cavité 12 de façon que la cavité 9 de chaque plage de connexion interne 4 du module 1 s'étende en regard du débouché d'un perçage 13. La colle conductrice 14 contenue dans les perçages 13 assure la liaison électrique entre les bornes de l'antenne 11 et les plages de connexion  The module 1 is fixed with glue 15 of cyanoacrylate type in the cavity 12 so that the cavity 9 of each internal connection pad 4 of the module 1 extends opposite the outlet of a bore 13. The conductive glue 14 contained in the holes 13 provides the electrical connection between the terminals of the antenna 11 and the connection pads

interne 4.internal 4.

On comprend que les bandes 8 forment une zone isolée entre les plages de connexion externe 5 et le pourtour du film support de sorte que le risque d'une remontée de colle suffisamment importante pour atteindre  It is understood that the strips 8 form an isolated area between the external connection pads 5 and the periphery of the support film so that the risk of a glue rise sufficiently significant to reach

une plage de connexion externe est pratiquement éliminé.  an external connection range is practically eliminated.

De plus, la colle conductrice 14 en excès est  In addition, the excess conductive adhesive 14 is

reçue dans les cavités 9 des plages de connexion interne 4.  received in the cavities 9 of the internal connection pads 4.

Les cavités 9 permettent donc de limiter l'écoulement de colle conductrice et éviter ainsi qu'une quantité trop importante de colle ne remonte par capillarité entre les bords de la cavité 12 et le bord du film support 2 et  The cavities 9 therefore make it possible to limit the flow of conductive adhesive and thus prevent an excessive amount of adhesive from rising by capillary action between the edges of the cavity 12 and the edge of the support film 2 and

risque d'atteindre des plages de connexion externe.  risk of reaching external connection ranges.

Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des  Of course, the invention is not limited to the embodiment described and it is possible to add to it

variantes de réalisation sans sortir du cadre de l'inven-  variant embodiments without departing from the scope of the invention

En particulier, bien que la zone périphérique  In particular, although the peripheral area

isolée électriquement du circuit intégré ait été représen-  electrically isolated from the integrated circuit has been shown

tée par une bande métallique 8, on peut réaliser cette zone isolée électriquement en laissant nue la seconde face du film support dans cette zone. On peut par exemple prévoir que la zone périphérique soit formée d'une bande nue s'étendant sensiblement sur tout le pourtour de la seconde face. Bien que la cavité 9 ait été représentée en forme de spirale, on peut réaliser une cavité 9 en arc de cercle s'étendant à proximité du pourtour externe de la plage de  ted by a metal strip 8, this electrically isolated zone can be produced by leaving the second face of the support film bare in this zone. One can for example provide that the peripheral zone is formed of a bare strip extending substantially over the entire periphery of the second face. Although the cavity 9 has been shown in the form of a spiral, it is possible to produce a cavity 9 in an arc extending in the vicinity of the outer periphery of the range of
