Definitions

  • the invention relates to a data carrier according to the preamble of claim 1.
  • Such a data carrier has become known from EP 0710919 A2.
  • This comprises an electronic module with an integrated circuit (semiconductor chip) and a wire-wound coil, the integrated circuit resting directly on the wound coil.
  • the coil is encapsulated with a potting compound in the area of the integrated circuit.
  • Data carriers of the generic type are known, in particular, in the form of a contactless chip card designed in the form of a credit card, which can be used in an extremely versatile manner due to its high functional flexibility.
  • chip cards in the form of health insurance cards, flextime recording cards, telephone cards and the like, there will in particular be applications in future in local public transport where as many people as possible have to be recorded in the shortest possible time. In such applications, contactless offer
  • Chip cards have advantages over contact-based chip cards in that the former are not necessarily in a reading or Must be plugged in, but function without contact over a distance of up to a few meters.
  • the contactless chip card offers the advantage that no technical elements are visible on the card surface, so that the optical design of the card surface is not restricted by magnetic strips or contact areas.
  • the disadvantages of the contactless chip cards currently available are primarily the additional components, such as transmission coils or capacitor plates, which have to be integrated into the card.
  • the electronics required in the contactless chip card for the contactless transmission of electrical signals to the reading or writing station are more complex.
  • circuits are suitable for this purpose which enable signal transmission by means of microwaves, optical signals, capacitive or inductive coupling, the capacitive and inductive coupling being the most suitable due to the flat design of the chip card.
  • Most contactless cards are currently being transmitted inductively, which can be used to implement both data and energy transmission.
  • One or more induction coils are thus integrated in the card body and are suitably contacted with the circuit located on the semiconductor chip.
  • the transmission of electrical signals is based on the principle of the loosely coupled transformer, the carrier frequency being, for example, in the range between 100 and 300 kHz or a few MHz, in particular the industrial frequency of 13.56 MHz.
  • induction coils with an opposite to the bottom surface of the semiconductor chips of the order about 10 mm 2 substantially larger coil areas of typically from about 30 to 40 cm 2 is required, the induction coil having as a rule only a few turns and is formed flat.
  • the semiconductor components are mounted in the form of prefabricated modules or directly as a chip on the etched coil.
  • the card is laminated into the card body, with intermediate foils, if necessary provided with punched-outs, being inserted as ticking foils for the purpose of volume compensation during lamination.
  • the contactless chip cards used so far were all made with all-plastic materials and mostly in outer dimensions that correspond to the ISO standard dimensions. Characteristic of these standard specifications is furthermore a high mechanical flexibility of the card body, which, however, requires special measures to protect the semiconductor chip, which is very sensitive to bending or torsional stress, which results in a complex and consequently costly production and assembly effort for the contactless chip card.
  • the contactless chip cards, which are to be manufactured according to the ISO standard consist of individual plastic layers that are laminated on top of each other.
  • the production of the card structure, which generally consists of six to seven plastic layers, and the subsequent surface design with regard to labeling and provision of a coating layer are particularly complex. The associated high manufacturing costs of such contactless chip cards cannot usually be borne by all desired applications.

  • the data carrier body has two cardboard or paper layers, between which a stiffening at least partially surrounding the semiconductor chip element is introduced.
  • the stiffening element is formed at least in regions by the turns of the induction coil.
  • Deviating from the ISO standard specifications a data carrier that can be manufactured extremely inexpensively is proposed in the sense of a low-cost chip card that does without the all-plastic body.
  • the overall strength of the data carrier according to the invention can be increased compared to the ISO standard specifications, so that special measures for protecting the semiconductor chip, as are required in the previous chip cards according to the ISO standard, can be omitted.
  • the windings of the induction coil inserted between the two cardboard or paper layers are arranged at the same height and at the same mounting level as the semiconductor chip or the semiconductor chip housing and thus at the same time as a stiffening element
  • the turns of the induction coil which are made of enamelled wire, have a diameter of at least 200 ⁇ m, in particular preferably of at least 500 ⁇ m.
  • the induction coil inserted between the two cardboard or paper layers is assigned a coil core, in particular ferrite core, which at least partially surrounds the semiconductor chip or a semiconductor chip housing or at least approximately positively accommodates it, and its overall height and mounting level in turn that of the semiconductor chip or the semiconductor chip housing corresponds.
  • the coil core like the turns of the induction coil made of thick wire, serves as a stiffening element for mechanical protection of the semiconductor chip.
  • the data carrier according to the invention differs from Known all-plastic chip cards are significantly more resistant to bending, making special protective measures for the semiconductor chip against mechanical loads unnecessary.
  • the two cardboard or paper layers of the data carrier body are provided with an adhesive or adhesive layer on their surface facing the semiconductor chip.
  • the adhesive or adhesive layer is used both to assemble the data carrier body and the components to be inserted therein, and to compensate for differences in height of the individual components.
  • a more than about 20 ⁇ m thick, cold-adhesive layer is preferably used for the adhesive and adhesive layer.
  • a support frame inserted between the two cardboard or paper layers is provided at the edge region of the data carrier body.
