Definitions
- the invention relates to a data carrier with a flat, flexible substrate, a production method for such a data carrier and the use of such a data carrier.
- Data carriers in the sense of the present invention are in particular security or value documents, such as bank notes, passports, identification documents, check forms, shares, certificates, stamps, vouchers, flight tickets and the like, as well as labels, seals, packaging and other elements for product security.
- security or value documents such as bank notes, passports, identification documents, check forms, shares, certificates, stamps, vouchers, flight tickets and the like, as well as labels, seals, packaging and other elements for product security.
- data carrier in the following includes all such documents and product securing means.
- the documents mentioned have in common that their commercial or utility value far exceeds their material value.
- complex measures are taken to make the documents distinguishable from imitations or forgeries.
- they are provided with security elements which, on the one hand, are difficult to imitate and, on the other hand, also enable a layperson to check the authenticity of the security element.
- printing areas produced by intaglio printing are characterized by a characteristic tactility that is easily recognizable even for the layperson, and which cannot be reproduced by other printing processes and in particular by copiers or scanners.
- the tactile contours on the other hand represent a point of attack for manipulations, since the microchip can be found immediately in the banknote.
- the spatial structure of the contour also leads to problems with regard to the desired easy stackability and the automatic processing of banknotes.
- the area of the banknote provided with the microchip is exposed to increased abrasion in daily circulation, which leads to locally increased mechanical signs of wear and tear, up to the detachment of the chip.
- the object of the invention is to create a data carrier which is improved compared to the prior art and in which, in particular, an inserted microchip is protected against being found easily and against mechanical stress.
- the substrate of a data carrier has at least one deep embossing in which a circuit module is arranged.
- the circuit module is therefore first of all protected against mechanical stress and, on the other hand, it is visually and palpably less noticeable.
- the deep embossing of the substrate is preferably produced in intaglio printing.
- a high-resolution steel engraving engraving technique according to EP 0906193 AI can advantageously be used, in which intaglio printing plates are milled by means of an electronically controlled stylus, so that very fine and extremely precise engravings of the printing plate are possible.
- the deep embossing is characterized in a "advantageous embodiment of the data carrier without assignment of the printing plate with ink, that is, it is blind embossed. This large structure depths in the flexible substrate can particularly be achieved.
- the circuit module is expediently glued into the deep embossing. Both a non-conductive and a conductive adhesive can be used. If the circuit module in flip-chip assembly is brought into contact with the contact areas of an antenna structure or the like, an anisotropically conductive adhesive (ACA) or an anisotropically conductive film (anisotropically conductive adhesive) is used for fixing and simultaneous electrical contacting of the module. Anisotropically Conductive Film (ACF) is used. These are adhesives with an insulating matrix that is filled with electrically conductive particles. Due to the low particle density, the adhesive is not conductive in the basic state. Only by pinching the Adhesive between two contact surfaces creates an electrical conductivity in the direction of the connecting line of the contact surfaces.
- ACA anisotropically conductive adhesive
- anisotropically conductive adhesive anisotropically conductive adhesive
- ACF Anisotropically Conductive Film
- the lateral dimension and the depth of the deep embossing are expediently matched to the size of the circuit module in order to enable the circuit module to be received. It is advantageous if the deep embossing is produced with a lateral dimension that is only slightly larger than the circuit module.
- the lateral dimensions of the deep embossing can be chosen to be 3% to 10% larger than the dimensions of the circuit module.
- the depth of the embossing is preferably greater than the height of the circuit module, so that it is completely received in the recess of the embossing.
- a small protrusion of the circuit module can be absorbed by further applied layers, such as a cover element or a lacquer layer. In both cases, the block cannot be detected tactilely.
- a certain protrusion of the circuit module can easily be accepted, since the surface of the data carrier has a tactile structure in any case due to the embossing, in which the small protrusion of the integrated circuit module does not emerge.
- the lateral dimensions of the circuit module can be, for example, 0.2 mm x 0.2 mm to 1 mm x 1 mm.
- Microchips with a thickness of approximately 200 ⁇ m or less are already common today.
- the thickness of the building blocks is only a fraction of the thickness of the flexible substrate.
- circuit modules with a thickness of approximately 15 to approximately 60 ⁇ m are then expediently used.
- chip modules are advantageously used instead of mere semiconductor components, in which the circuit component is attached to a carrier. Such modules can easily be brought into electrical contact with an antenna structure.
- the total thickness of such a module is currently approximately 220 ⁇ m or less.
- the substrate has a plurality of similar deep embossings, the circuit module being arranged in one of the similar embossments.
- the installation location of the integrated circuit module can be varied, so that localization and thus manipulation of the module is made more difficult. If the deep embossing is distributed over a certain area, for example a few square centimeters, or even over substantially the entire area of the data carrier substrate, then practically unchanged good flatness and stackability of the data carriers can be achieved despite the deep embossing. Good stackability is particularly important for documents of value, such as banknotes.
- the deep embossing or the plurality of similar deep embossings forms part of an image motif, such as a portrait, a landscape motif, an animal motif, an architectural representation or the like, according to an advantageous development of the invention .
- image motifs are already on many value documents, so that the Users did not readily notice the additional use of deep embossing as a container for a microchip.
- the flat substrate of the data carrier has a front side and a back side, the depression of the embossing with the circuit module arranged therein being arranged on the rear side of the substrate.
- the deep embossing on the back of the substrate is expediently closed by an opaque cover element.
- the cover element can comprise a metallic optical security element, such as a metallic embossed hologram, for example in the form of a strip or label, or an opaque lacquer layer.
- the circuit module is both protected and hidden by the cover element.
- all types of transfer elements as described, for example, in publication WO 02/02350, can also be used as cover elements.
- the cover element is electrically conductive and forms a coupling element for contactless correspondence communication between the integrated circuit module and a read / write device.
- a coupling element for contactless correspondence communication between the integrated circuit module and a read / write device.
- it can represent a capacitive antenna area or a coil for inductive coupling.
- the front of the substrate is provided with a conductive surface in the area of the deep embossing, which forms a coupling element for contactless communication of the integrated circuit module with a read / write device.
- the conductive surface can be in the form of a strip, label or medal. It becomes expedient on the flat Data carrier substrate printed, for example using silver conductive ink in screen printing.
- the shape and dimensions of the conductive surface and the cover element are matched to one another in order to produce a continuous visual impression.
- the cover element can also be designed in the same size in the form of a medal and can be arranged with the conductive surface on the back so that a continuous medal effect is achieved by both elements.
- the conductive surface is preferably provided with a visual and / or machine-testable optical effect which increases the security against forgery of the data carrier.
- the coupling element which can be formed by a conductive surface on the front of the substrate or by a conductive cover element, preferably represents a loop dipole, a coil or an open dipole.
- an antenna structure is applied to the back of the data carrier substrate.
- the antenna structure is preferably printed on the substrate, for example using silver conductive ink in screen printing.
- the antenna structure is advantageously integrated into a graphic image motif on the back of the substrate, on the one hand to make the presence of an antenna less obvious and on the other to achieve an attractive overall graphic design.
- the graphic image motif can be executed, for example, in offset or flexographic printing.
- contact surfaces are preferably provided for the electrical connection of the circuit module to the antenna structure.
- the circuit module can be brought into electrical contact with these contact areas, for example by flip-chip assembly.
- the circuit module can be glued into the deep embossing with an anisotropically conductive adhesive (ACA) or via an anisotropically conductive film (ACF), and at the same time electrical contact can be made with the contact surfaces of the deep embossing.
- ACA anisotropically conductive adhesive
- ACF anisotropically conductive film
- contact areas for the electrical connection of the circuit module to the antenna structure are applied to the circuit module. Since the module in this variant is already deeply embossed when the contact surfaces are applied, care must be taken to ensure that the mechanical loads on the circuit module and the deep embossing are kept as low as possible. This can be achieved, for example, by printing on the contact areas using the screen printing method.
- the shape of the antenna structure is matched to the arrangement of the plurality of similar deep embossments, so that the circuit module can be brought into contact with the antenna structure in each of the plurality of deep embossments.
