Definitions

  • the invention relates to a carrier element for an IC module for installation in a chip card with a plate-shaped support body, on the front flat side of which metallic contact surfaces are arranged and on the other rear flat side of which the IC module is arranged, from a protective layer covering the IC module a potting material and an adhesive surface applied to the back of the support body for fixing the carrier element to the chip card and a method for its production.
  • Carrier elements of the generic type are usually manufactured as mass components in the context of modular belts on which a large number of carrier elements are processed at the same time, equipped with the IC component and wired and then arranged in a separate operation on corresponding chip cards, the chip cards increasing Dimensions can be used in all areas of daily life, for example in the form of telephone cards, access authorization cards for mobile telephones, bank cards, etc.
  • the carrier elements used for the chip cards are inserted into the cards so that the front side of the plate-shaped carrier body with its metallic contact surfaces forms a contact field for connecting the IC component arranged on the carrier element to external data transmission or reading devices.
  • the IC component as
  • the computer module is protected on the back of the carrier body of the carrier element in a recess in the chip card.
  • the support body is designed in such a way that there is an adhesive surface on its back around the IC module.
  • the middle region of the carrier plate, in which the IC component and a protective layer covering it from a potting material are arranged, is kept free from the adhesive applied in the edge regions according to the prior art.
  • the application of the adhesive for fastening the support body within the chip card is usually carried out with the aid of an adhesive film for this purpose, holes are provided in a separate work step, in which the IC component and the potting material are to be arranged later.
  • Such a construction of the carrier element contains two serious disadvantages.
  • the carrier element is designed in such a way that the adhesive surface as a full-surface adhesive layer covers the entire rear surface of the carrier element.
  • the method according to the invention for producing a carrier element according to the main claim provides that the full-surface adhesive layer is fixed to the carrier element by a pressing process by means of a pressure device with a pressure surface made of an elastic material, the pressure surface being so flexible that the carrier element with its entire surface the IC module and the back covering covering it can dip into the pressure pocket.
  • the adhesive layer is designed as a multilayer laminate coating with at least one adhesive coating facing the carrier element and at least one carrier layer covering the adhesive coating on the side facing away from the carrier element.
  • the laminate coating reliably prevents adhesion between the pressure surface and the adhesive layer during the pressing process for the adhesive layer.
  • the outer shape of the pressure surface can be realized in different ways. It has proven to be advantageous to design the pressure surface as a pressure roller, which permits continuous transport of the module belt provided with the individual carrier elements and, under certain circumstances, can additionally support this continuous transport as a driven pressure roller.
  • the pressure roller used has a diameter of 10 to 40 mm. , 4th
  • FIG. 1 a cross section of a carrier element according to the invention
  • FIG. 2 the carrier element according to the invention from FIG. 1 installed in a chip card and
  • the carrier element designated 1 in its entirety in FIG. 1 has an inner plate-shaped support body 2 which has a plurality of metallic contact surfaces 5 on its front flat side. In their entirety, the metallic contact surfaces 5 form a contact field, the contact surfaces being separated from one another by gaps 17.
  • An IC module 3 is arranged on the rear side facing away from the front flat side of the supporting body 2. The circuits of this component 3 are connected to the contact surfaces 5 via a plurality of connecting wires 15. For this purpose, there are several bores 16 in the support body 2 through which the individual connecting wires 15 are guided.
  • the IC module 3 is covered with a protective layer 6 made of a potting material after being wired to the contact areas 5.
  • the protective layer 6 is in turn enclosed by an adhesive layer 7 which extends over the entire surface of the entire rear surface of the carrier element. Due to the design according to the invention, punching out the adhesive surface of the carrier element in the area of the protective layer 6 is now superfluous, as a result of which the production costs can be significantly reduced. In addition, according to the invention, the shape of the "hill" of the potting material covering the IC module 3 is no longer relevant, so that control measures before applying the adhesive layer 7 are unnecessary. It can also be seen from FIG. 1 that the adhesive layer 7 as a laminate is provided with an internal adhesive coating 9 facing the support body 2 and a carrier layer 8 applied to the outside of the adhesive coating 9.
  • the carrier layer 8 allows the adhesive layer 7 to be easily applied to the rear of the carrier element 1, as will be explained in detail in the description of the method.
  • FIG. 1 thus represents a single carrier element which is used as an overall component in a chip card.
  • a chip card 4 with the carrier element 1 inserted therein is shown in section in FIG. 2.
  • the carrier element 1 is placed in a step-shaped recess 14 within the chip card 4.
  • the recess 14 has an internal recess 18 and a stepped collar area 19 on which the edge of the support body 2 rests.
  • the adhesive bond between the support body 2 and the chip card 4 takes place exclusively in this collar region 19, since the depth 18 of the recess 18 is dimensioned such that a gap, albeit small, remains between the outer surface of the adhesive coating 9 and the bottom of the recess 18.
  • FIGS. 3 a and b it is shown schematically how a connection between the carrier element 1 or the protective layer 6 and the carrier body 2 and the adhesive layer 7 can be brought about with the aid of a pressure surface 20 by a pressing process.
  • the method for producing a carrier element of the type described above provides that the individual carrier elements are combined to form modular belts on which a large number of individual carrier elements are located at the same time.
  • the above-mentioned adhesive layer 7 is placed on the outside of the protective layer 6, and in such a way that the adhesive layer 7 consisting of the carrier layer 8 and the adhesive coating 9 faces with its adhesive side to the protective layer 6 or to the support body 2. Then with the help of an elastic material existing pressure surface brings about a permanent bond between the adhesive layer 7 and the carrier element 1. To implement this method step, it is necessary that the elastic material of the pressure surface is so flexible that the support element 1 with its back side provided with the IC module and the protective layer 6 covering it can be completely immersed in the pressure surface. Only through complete immersion is it ensured that the adhesive layer 7 is also connected to the supporting body material 2 in the depressions located between the individual “hills” of the modular belt.
  • the pressure surface 20 is shown as a pressure pad 21 which is pressed onto the module belt with a force F, a counter-holder 23 preventing the module belt from escaping in the direction of the direction of action of the force F.
  • the pressing force F is to be dimensioned such that a sufficient pressing force for permanent fixation between the support body 2 and the adhesive layer 7 is brought about even in the depressions located between the "hills" of the modular belt.
  • FIG. 3 b A further embodiment variant of the pressure surface 20 is shown in FIG. 3 b.
  • the pressure surface is designed as a circumferential pressure roller 22, a counter-holder 23 in turn preventing the module belt from escaping in the direction of the force F.
  • the distance from the center of the pressure roller 22 is dimensioned in this embodiment such that the lower areas between the support elements are also touched.
  • the configuration with a pressure roller 22 has the advantage that a continuous transport movement of the module belt with the individual support elements 1 can be carried out.
  • Foam and rubber with a correspondingly necessary softness are particularly suitable as advantageous material for the pressure roller 22 and the pressure pad 21.
  • the pressure device for the method according to the invention with special additional features.
  • Essential to the invention is the coordination of the material properties of the pressure roller or the pressure pad with regard to the material properties of the potting compound for the IC module in such a way that the pressure surface is softer than the potting compound.

Abstract

L'invention concerne un élément support pour module à circuit intégré à monter dans une carte à puce, comportant : un corps support sous forme de plaque sur la face plate avant de laquelle sont aménagées des surfaces de contact métalliques, le module à circuit intégré étant monté sur sa face plate arrière ; une couche de protection en matériau de remplissage recouvrant le module à circuit intégré et une surface adhésive appliquée sur la face arrière du corps support et destinée à fixer l'élément support sur la carte à puce. En tant que couche adhésive en nappe, la surface adhésive recouvre l'ensemble de la surface arrière de l'élément support. Cette structure permet de réduire de manière non négligeable les frais de production de l'élément support objet de l'invention. l'invention concerne en outre un procédé permettant de produire un élément support de ce type, selon lequel la couche adhésive qui couvre toute la surface est fixée sur l'élément support par compression à l'aide d'un dispositif de compression à surface de compression réalisée dans un matériau élastique. La surface de compression est si souple que l'élément support peut s'enfoncer en elle, par sa face arrière munie du module à circuit intégré et de la couche de protection le recouvrant.
