  • Patent number: 4792843
    Abstract: A multilayer data carrier into which a carrier element supporting an IC module is incorporated comprises a flexible substrate on which contact surfaces are formed which are connected to the IC module via leads. The carrier element is deformed in such a way, when being incorporated into the data carrier, that the IC module, in the finished data carrier, is located in the center of the card protected by cover layers of the card and the contact surfaces are flush with the surface of the card. A method for producing the data carrier comprises laminating a substrate layer carrying an IC-module with its leads and contact pad surfaces on one surface thereof between outer protective layers and with a central core layer such that the IC-module is disposed centrally within the data carrier with the contact surfaces disposed in apertures in one of the outer protective layers flush with the surface of said one layer.

  • Patent number: 4711690
    Abstract: The multilayer identification card comprises several synthetic layers compounded by the effects of heat and pressure. An inside interface of at least one of these layers exhibits depressions which are filled with the material of the adjacent layer during the laminating process. The adjacent layers are selected in such a way that they are of different transparency. Thus a light and shadow effect is produced in incident light which is reversed in transmitted light.

  • Patent number: 4639585
    Abstract: The integrated circuit embedded in a data carrier and the contact surfaces connected with this circuit are to be protected against bending of the data carrier. For this purpose, the data carrier is divided into two areas, the first one, which bears the circuit and is generally small compared to the second area, being connected to the second area via a predetermined breaking point. Stress which occurs when the data carrier is bent is kept away from the circuit, or transmitted only weakly to it, by the predetermined breaking point.

  • Patent number: 4617216
    Abstract: An identification card equipped with an integrated circuit, in which the circuit along with its connection leads is arranged on a carrier element which is embeddedly enclosed by the card on all sides by use of the hot lamination technique. In order to protect the sensitive arrangement, the carrier element is subjected to the full laminating pressure only when one or more layers in the card construction have softened.This is achieved, for example, by providing buffer zones in the card laminate at least in the area of the arrangement in the form of cavities or layers that are easy to deform elastically. The buffer zones protect the arrangement from local pressure peaks in the initial phase of the laminating process. It is also possible to control the laminating pressure as a function of the temperature or the degree of softening of the card layers.

  • Patent number: 4617605
    Abstract: A carrier element for an IC module for incorporation into data carriers, in which the IC module is connectd with contact surfaces by means of leads, and the contact surfaces are designed for direct contacting.In order to protect the Integrated Circuit against destruction due to static charges, measures are provided to dissipate outside the circuit any portions of charge that may occur. In one embodiment, all terminals of the circuit have a low resistance connection with each other. The connection is suspended during each operational phase and is then restored. In a further embodiment, the terminals are bridged by spark gaps. This protective step is advantageous in that it is not necessary to remove and then restore the bridging.

  • Patent number: 4603249
    Abstract: A multilayer identification card is equipped with an IC module. The module is arranged on a carrier element which is located in a recess in the multilayer card. The card layers bordering the recess bear supporting layers which are thermoresistant in the range of hot lamination temperatures. This prevents the recess from becoming filled with fluid card material during the hot laminating process, during which the card layers will soften and eventually become fluid. Thus, the IC module can advantageously give way within the recess when the card is bent. Further, the supporting layers have a stabilizing effect on the adjacent card layers and thereby prevent irregularities caused by incorporation of the carrier element from being passed onto the card surface.

  • Patent number: 4587413
    Abstract: An identification card having an IC module for the processing of electrical signals. The IC module (9) and the leads (6) and contact surfaces (5, 20) necessary for the operation of the module are attached to a separate carrier (7, 17) and embedded in the identification card in such a way that the IC module is located in an area (4) of the card having the maximally permitted thickness, whereas the contact surfaces are arranged outside this area. The placement of the IC module in the elevated card area (e.g. the impressing area) allows for a thicker encapsulation of the module and correspondingly better protection against mechanical stress. On the other hand, the area of the carrier element with the contact surfaces is arranged outside the elevated area of the card, for example in the magnetic stripe area (2).

  • Patent number: 4549247
    Abstract: A carrier element for IC modules, whereby several leads are arranged on a carrier film, which leads are each connected at one end with a terminal of the module and run into a contact surface at the other end. Whereas the contact surfaces are arranged on the side of the film not touching the module within the periphery of the module, the outer leads are connected with the corresponding terminals of the module through punched out windows in the film. The carrier element thus has a very compact form, the area of which is adapted to the size of the IC module.
