Description
Plastikkarte für elektronisches Combi-Card-Modul Plastic card for electronic combi card module
Die Erfindung betrifft eine laminierte Plastikkarte, die mehrere Deckfolien und eine Antennenfolie enthalt und bei der eine aus Draht bestehende Antennenspule vor dem Laminieren auf der Antennenfolie angeordnet wurde, wobei sich die Antennenspule schichtmittig in der Plastikkarte befindet und bei der nach dem Laminieren in die Plastikkarte eine Kavitat eingearbeitet wurde, die zur Aufnahme eines Combi Card Moduls, welches in unterschiedlichen Hohen angeordnete innere Kontakte und äußere Kontakte aufweistThe invention relates to a laminated plastic card which contains a plurality of cover foils and an antenna foil and in which an antenna coil consisting of wire has been arranged on the antenna foil prior to lamination, the antenna coil being located in the middle of the layer in the plastic card and one being laminated into the plastic card Cavity was incorporated to accommodate a Combi Card module, which has internal contacts and external contacts arranged at different heights
In derartigen Plastikkarten wird nach dem Laminieren eine stufenförmige Kavitat eingefrast und in diese das elektronische Modul eingeklebt Das eingesetzte elektronische Combi Card Modul kann über seine nach außen weisenden Kontaktflachen direkt über elektrische Kontaktierungs- und Verbindungseinrichtungen und außerdem über seine zum Karteninneren weisenden inneren Kontaktierungsflachen, die mit einer Antennenspule verbunden sind, über elektromagnetische Felder und über entsprechende Empfangseinrichtungen mit Datenverarbeitungseinrichtungen kommunizieren
Bei der Herstellung dieser Kombikarten muß eine sichere Kontaktierung des Moduls mit der sich im Karteninneren befindenden Antennenspule erzeugt werden Um eine dauerhafte Planlage der Plastikkarte sowie ein gutes Design zu gewahrleisten werden, insbesondere bei drahtformigen Antennenspulen, die Antennenspulen schichtmittig oder nahezu schichtmittig im Laminat angeordnet, wahrend sich die inneren Anschlüsse des elektronischen Combi Card Moduls nach dem Einkleben in der Randschicht der Plastikkarte befinden Außerdem erfordert die durch den Laminiervorgang verursachte relativ große Lagetoleranz der Antennenan- Schlüsse gegenüber der Lage der Kavitat, daß der Antennenanschlußbe- reich eine so große Flache aufweisen muß, daß genügend große Flachenelemente der inneren Anschlüsse der elektronischen Combi Card Moduls mit den Flachenelementen der Antennenanschlusse mit Sicherheit miteinander zu kontaktieren sind.After laminating, a step-shaped cavity is milled into such plastic cards and the electronic module is glued into it. The electronic Combi Card module used can be directly connected via its contact surfaces pointing outwards via electrical contacting and connecting devices and also via its internal contacting surfaces facing the inside of the card an antenna coil are connected, communicate with data processing devices via electromagnetic fields and via corresponding receiving devices When producing these combination cards, a secure contact must be made between the module and the antenna coil inside the card.To ensure a permanent flatness of the plastic card and a good design, especially in the case of wire-shaped antenna coils, the antenna coils are arranged in the laminate or almost in the middle of the laminate the internal connections of the electronic Combi Card module are in the edge layer of the plastic card after gluing. Furthermore, the relatively large position tolerance of the antenna connections caused by the lamination process relative to the position of the cavity means that the antenna connection area must have such a large area, that sufficiently large flat elements of the internal connections of the electronic Combi Card module with the flat elements of the antenna connections are to be contacted with one another with certainty.
Von der Firma Ama Tech GmbH & Co KG, Pfronten/BRD, wurde hierzu vorgeschlagen, einen biegesteifen, geschlossenen Stutzring, der an mindestens zwei Bereichen metallisiert ist, entlang der Combi Card Modulperipherie in die Plastikkarte einzulaminieren Dabei ist auf einer Stutzπngseite an dem metallisierten Bereich der Antennenanschluß befestigt und an dem metallisierten Bereich auf der anderen Stutzringseite wird nach Freifrasen der Kavitat der innere Anschluß des elektronischen Combi Card Moduls kontaktiert Nachteilig ist bei dieser Losung der relativ hohe Aufwand für das Herstel- len, Einbringen und Kontaktieren des Stutzringes, sowie die Beeinträchtigung des Kartendesigns im Bereich des StutzringesThe company Ama Tech GmbH & Co KG, Pfronten / FRG, proposed for this purpose to laminate a rigid, closed support ring, which is metallized on at least two areas, along the Combi Card module periphery into the plastic card. On one side of the support on the metallized area the antenna connection is fastened and the inner connection of the electronic Combi Card module is contacted after the cavity has been cut free on the metallized area on the other side of the support ring. The disadvantage of this solution is the relatively high outlay for producing, inserting and contacting the support ring, and the impairment of the card design in the area of the support ring
In Stand der Technik ist es weiterhin bekannt, Chipkarteninlays mit atztechnisch hergestellten Spulen zu verwenden, bei denen die Leiterbah- nen in relativ großflächige Antennenanschlußbereiche übergehen
Nachteilig sind hierbei jedoch die hohen Kosten für die Herstellung der Spulen, sowie die gegenüber Drahtspulen schlechteren Gutewerte der geatzten SpulenIt is also known in the prior art to use chip card inlays with coils produced by etching technology, in which the conductor tracks merge into antenna connection areas of relatively large area However, the high costs for the production of the coils and the poorer values of the etched coils compared to wire coils are disadvantageous here
Der Erfindung liegt die Aufgabe zugrunde, eine laminierte Plastikkarten mit einer drahtformigen Antennenspule anzugeben, bei der zur Kontaktierung der Antennenspule mit den inneren Anschlüssen des elektronischen Combi Card Modul Anschlußbereiche für die Antennenspule in geeigneter Große und Tiefenlage in der Plastikkarte mit einfachen Mitteln ermöglicht werdenThe invention is based on the object of specifying a laminated plastic card with a wire-shaped antenna coil in which connection areas for the antenna coil in a suitable size and depth in the plastic card are made possible with simple means for contacting the antenna coil with the inner connections of the electronic combi card module
Erfindungsgemaß wird die Aufgabe dadurch gelost, daß die Dicke der Antennenfolie und der daruberliegenden Deckfolien so ausgeführt ist, daß die Unterseite der Antennenfolienschicht nach dem Laminieren im Abstand der Hohe der inneren Kontakte des Combi Card Moduls von der Plastik- kartenoberflache entfernt ist und daß die Antennenspule in Teilbereichen durch die Antennenfolie bundig zur deren Unterseite gedruckt istAccording to the invention, the object is achieved in that the thickness of the antenna film and the cover films lying thereover are designed such that the underside of the antenna film layer is removed from the plastic card surface after lamination at a distance equal to the height of the internal contacts of the Combi Card module, and that the antenna coil in some areas is printed flush to the underside of the antenna film

Die Erfindung ermöglicht mit einfachen Mitteln großflächige Antennenan- schlußbereiche in definierten Schichtenlagen der Plastikkarte zu erzeugenThe invention enables large-area antenna connection areas to be produced in defined layers of the plastic card with simple means
Durch die Verbreiterung des Anschlußbereiches mit schleifenfbrmigen Antennendrahtruckfuhrungen sowie durch die Gestaltung der
Drahtzuführung von der Antenne zum Anschlußbereich jeweils von der Kavitat ausgehend bleiben selbst dann, wenn beim Einfrasen der Kavitat Teile der Drahtlagen beschädigt werden, in den Anschlußbereichen die Zuführung sowie ein genügend breiter Anschlußbereich erhaltenBy widening the connection area with loop-shaped antenna wire returns and by designing the The wire feed from the antenna to the connection area, starting from the cavity, remains in the connection areas, even if parts of the wire layers are damaged when milling the cavity, the feed and a sufficiently wide connection area are retained
Es ist vorteilhaft, die Drahtschleifen im Anschlußbereich nur stegweise an die Unterseite der Antennenfolie zu drucken Damit wird eine optimale Verankerung der Drahtschleifen in der Antennenfolie erreicht, ohne daß Designbeeintrachtigungen der Plastikkarte dadurch auftreten, daß die Antennenseite der Antennenfolie durch die Druckwerkzeuge beschädigt werden Außerdem stehen nach dem Freifrasen der Kavitat auch bei Einfrasen in den Antennendraht Anschlußbereiche zur Verfügung, die voll funktionsfähig sind Dies kann noch dadurch unterstutzt werden, daß für den Antennendraht versilberte Drahte verwendet werden und daß nach dem Fräsen der Kavitat die Antennenanschlußbereiche durch Laserstrahlung von eventuellen Plastikresten gereinigt werden Es ist weiterhin vorteilhaft, beim stegweisen Durchdrucken von Anschlußbereichen den Antennendraht gleichzeitig so zu deformieren, daß seine Breite vergrößert wird Das Durchdrucken kann durch thermischen, durch Ultraschall- oder kombinierten Energieeintrag in das Druckwerkzeug erfolgenIt is advantageous to only print the wire loops in the connection area to the underside of the antenna film in a web-like manner.This ensures that the wire loops are optimally anchored in the antenna film without the plastic card being adversely affected by the design, in that the antenna side of the antenna film is damaged by the printing tools the free milling of the cavities, even when milling into the antenna wire, there are connection areas that are fully functional.This can be supported by the fact that silver-plated wires are used for the antenna wire and that after milling the cavity, the antenna connection areas are cleaned of any plastic residues by laser radiation it is also advantageous to deform the antenna wire at the same time in the case of web-like printing of connection areas in such a way that its width is increased. Printing through can be by thermal, by ultrasound or by combination energy input into the printing tool
Die Drahtantenne wird zweckmäßig mittels Drahtlegeverfahren durch direktes Einlegen des Drahtes in die Antennenseite der Antennenfolie hergestellt und es ist vorteilhaft dabei metallisch blanken, vorzugsweise oberflachenveredelten Draht zu verwenden Das Drahtlegeverfahren ermöglicht eine umweltschonende, kostengünstige und lageprazise Erzeugung der Antenne, die bei Verwendung von oberflachenveredeltem Draht sehr hohe Gutewerte aufweist Mit diesem Verfahren lassen sich auch die Drahtschleifen im Anschlußbereich einfach erzeugen Die Kontaktierung der inneren Kontakte des elektronischen Combi Card Moduls mit den freigefrasten und vorzugsweise durch intensive elektromagnetische
Strahlung gereinigten Anschlußbereichen der Antenne erfolgt zweckmäßig durch elektrisch leitfähigen, thermoplastischen Kleber mit einer Verarbeitungstemperatur und -zeit beim Verkleben, die gleich oder ähnliche der verwendeten Temperatur des Heißsiegelklebers zum elektrisch isolierenden Einkleben der weiteren Flächen des elektronischen Combi Card Moduls in die Kavitat der Plastikkarte ist.The wire antenna is expediently produced by means of a wire-laying process by directly inserting the wire into the antenna side of the antenna foil and it is advantageous to use bare metal, preferably surface-coated wire.The wire-laying process enables the antenna to be produced in an environmentally friendly, cost-effective and precise manner, which is very good when using surface-coated wire The wire loops in the connection area can also be easily produced with this method. The contacting of the internal contacts of the electronic Combi Card module with the free-milled and preferably through intensive electromagnetic Radiation-cleaned connection areas of the antenna are expediently carried out by means of electrically conductive, thermoplastic adhesive with a processing temperature and time during bonding which is the same or similar to the temperature of the heat seal adhesive used for the electrically insulating gluing of the further surfaces of the electronic combi card module into the cavity of the plastic card.
Soll der auf die Antennenschichtseite gelegte Draht beim Laminieren nicht teilweise in die Antennenfolie abtauchen, so ist es vorteilhaft, den Antennendraht zu fixieren. Dies kann durch Bedrucken der durch die Drahtwindungen gebildeten Sonderflächen nach dem Drahtverlegen oder mit einer bei Laminiertemperatur festen Kleberschicht erfolgen. Damit kann der Antennendraht im Bereich des Zentrums der Kavitat auf einem außermittigen Schichtniveau gehalten werden.If the wire placed on the antenna layer side is not to be partially immersed in the antenna film during lamination, it is advantageous to fix the antenna wire. This can be done by printing on the special surfaces formed by the wire windings after the wire laying or with an adhesive layer that is fixed at the lamination temperature. The antenna wire can thus be kept at an eccentric layer level in the region of the center of the cavity.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert. In den zugehörigen Zeichnungen zeigen:The invention is explained in more detail below using an exemplary embodiment. In the accompanying drawings:

In Figur 1 ist als Antennendraht 3 ein versilberter Kupferdraht mit eine Durchmesser von 100 m in fünf Windungen entlang der Peripherie der Plastikkarte 1 auf der Antennenseite 7 der Antennenfolienschicht 6 verlegt Der Antennendraht befindet sich in schichtmittiger bzw nahezu schichtmit- ttger Lage in der Plastikkarte 1 Beim Verlegen wird der Antennendraht 3 thermisch oder durch Ultraschallenergie etwa 80 m tief in die thermoplastische Antennenfolie 6 eingedrücktFigure 3 shows a plastic chip card cutout with Combi Card module. In FIG. 1, a silver-plated copper wire with a diameter of 100 m is laid in five turns along the periphery of the plastic card 1 on the antenna side 7 of the antenna film layer 6 as the antenna wire 3. The antenna wire is located in the layer or almost layer-middle position in the plastic card 1 Bei Laying the antenna wire 3 is pressed thermally or by ultrasonic energy about 80 m deep into the thermoplastic antenna film 6
Im Bereich der künftigen inneren Kontakte 18 des Combi Card Moduls 2 wurde der Antennendraht 3 in engen maanderfbrmigen Schleifen 13 hin- und hergeführt um einen breiten Anschlußbereich 4 zu schaffen Die Drahtzuführung 14 zum schleifenformigen Antennenanschlußbereich 4 erfolgte dabei von der Peripherie der vorgesehenen Lage des Combi Card Moduls 2 Der schleifenformige Antennenanschlußbereich 4 ist in kurzen Stegen 15 teilweise abgesenkt und liegt in Teilbereichen bundig zur Unterseite 8 der Antennenfolie 6In the area of the future internal contacts 18 of the Combi Card module 2, the antenna wire 3 was moved back and forth in tight meandering loops 13 to create a wide connection area 4. The wire feed 14 to the loop-shaped antenna connection area 4 was carried out from the periphery of the intended position of the Combi Card Module 2 The loop-shaped antenna connection area 4 is partially lowered in short webs 15 and in parts is located flush with the underside 8 of the antenna film 6

Wie aus Figur 1 weiter ersichtlich ist, verlaufen die mittleren Antennenwindungen 20 im Bereich des künftigen Zentrums des Combi Card Moduls 2 Um zu gewahrleisten, daß diese Antennenwindungen 3 beim Ausfrasen der Zentrumsstufenhohe 11 nicht zerstört werden, sind die mittleren Antennenwindungen 20 auf die Sonderflache 16 aufgelegt worden und ihre Höhenlage wurde in der künftigen laminierten Plastikkarte 1 als Sonderflache 16 mit einer beim Laminieren starren Klebeschicht 17 fixiertAs can also be seen from FIG. 1, the central antenna windings 20 run in the area of the future center of the Combi Card module 2. In order to ensure that these antenna windings 3 are not destroyed when the center step height 11 is milled out, the central antenna windings 20 are placed on the special surface 16 and their height was fixed in the future laminated plastic card 1 as a special surface 16 with an adhesive layer 17 that was rigid during lamination

nebeneinander liegenden Antennenanschlußbereiche 4 in Form von metallisch blank vorliegenden Drahtstücken. Damit wird eine sichere Kontaktierungsmög- lichkeit, selbst in den Fällen, in denen die Antennendrähte 3 angefräst wurden, geschaffen. Weiterhin zeigt Figur 3 eine vereinfachte Darstellung eines Combi Card Moduls 2 mit einer Beschichtung der inneren Kontaktfläche 18 mit elektrisch leitfähigen, thermoplastischen Kleber 22 und mit Heißsiegelklebefolie 23 vor dem Einsetzen und Einsiegeln in die Kavitat 9 der Plastikkarte 1.
