Abstract
Description
Die Erfindung betrifft eine thermoaktive Klebefolie zur Herstellung eines Datenträgers mit einer Aussparung in dessen Kartenkörper, in der ein Trägerelement anzuordnen ist. The invention relates to a thermoactive adhesive film for producing a data carrier a recess in the card body in which a carrier element is to be arranged.
Datenträger mit integriertem Schaltkreis sind bekannt und weit verbreitet, als Telefonkarten, Identifikationskarten etc. Darin können die Trägerelemente (Module) in dafür im Kartenkörper vorgesehene Ausnehmungen, mit herkömmlichen Lösungsmittel-Klebern eingeklebt sein.Data carriers with an integrated circuit are known and widely used as phone cards, identification cards etc. The support elements (modules) can be used in the Card body provided recesses, with conventional Solvent glue must be glued in.
Es gibt aber auch bereits Datenträger, in die die Trägerele mente mittels thermoaktivierbarer Kleberschichten eingeklebt werden, wie EP-A 299.530 und EP-A 334.733. Und schließlich ist aus EP-A 493.738 ein Datenträger mit integriertem Schaltkreis bekannt, in welchem das Trägerelement mittels einer thermoaktivierbaren Klebeschicht mit dem Kartenkörper verbunden wird, wobei zusätzlich eine Gußmasse zum Schutz des integrierten Schaltkreises vor mechanischen Belastungen verwendet wird.However, there are also data carriers into which the carrier elements can be found elements glued in with thermally activated adhesive layers such as EP-A 299.530 and EP-A 334.733. And finally is a data carrier with integrated from EP-A 493.738 Known circuit in which the carrier element by means of a thermally activated adhesive layer with the card body is connected, in addition a casting compound for protection of the integrated circuit against mechanical loads is used.
Die bekannten Datenträger und deren Herstellung weisen jedoch für die Praxis bedeutsame Nachteile auf. The known data carriers and their manufacture show however, significant disadvantages in practice.
So können mit herkömmlichen Klebern hergestellte Datenträger nur mit relativ langsamen Taktzeiten bearbeitet werden, was bei den großen Stückzahlen eine gravierende Begrenzung ist und zudem eine automatisierte Verfahrensweise erschwert. Aber auch die thermoaktivierbare Klebeschicht, die in Form einer Klebfolie eingesetzt wird, zeigt bei der praktischen Anwendung ihre Grenzen. Denn derartige Produkte, die als etwa 70 µm starke Klebfolien im Handel sind, verlangen eine Mindesttemperatur beim Heißverpressen von 120°C, um zu einer verläßlichen Verklebung zu führen. Bei einer derartigen, wenn auch nur kurzzeitigen Temperaturbeanspruchung werden die aus Kunststoff gefertigten Datenträger aber leicht beschädigt. Ferner treten im Boden der Datenträger Verfor mungen auf, die ihre spätere reibungslose Verwendung beein trächtigen können, z. B. bei Bank-Karten.So data carriers made with conventional adhesives can only be processed with relatively slow cycle times is a serious limitation for large quantities and also complicates an automated procedure. But also the thermally activated adhesive layer, which is in shape an adhesive film is used, shows in the practical Applying their limits. Because such products that as 70 µm thick adhesive films are commercially available, require one Minimum temperature during hot pressing of 120 ° C to become one to perform reliable bonding. With such a even if only be briefly exposed to temperature the data carriers made of plastic are light damaged. Furthermore Verfor occur in the bottom of the disk that affect their later smooth use can be pregnant, e.g. B. with bank cards.
Aufgabe der Erfindung war es, hier Abhilfe zu schaffen, insbesondere die thermoaktivierbare Klebefolie so auszugestalten, daß sie eine schnellere Herstellung der Datenträger bei geringeren Temperaturen ermöglicht.The object of the invention was to remedy this, in particular the thermo-activatable To design adhesive film so that it faster production of the disk allows lower temperatures.
Demgemäß betrifft die Erfindung eine thermoaktivierbare Klebefolie zur Herstellung eines Datenträgers, wie sie in den Patentansprüchen näher gekennzeichnet ist.Accordingly, the invention relates to a thermally activated adhesive film for producing a Data carrier, as it is characterized in the claims.
Die erfindungsgemäß erzielten Vorteile liegen insbesondere darin, daß eine geringere Verformung der Rückseite der Datenträger erfolgt und daß höhere Taktzeiten aufgrund einer schnelleren Aktivierung erzielt werden. Zudem wird es damit möglich, die Gesamtdicke des Moduls zu reduzieren, was bei den modernen Datenträgern ein beachtlicher Vorteil ist und die Frästiefe für die Aufnahme des IC-Bausteins zu verrin gern und damit einer Verformung des Datenträger-Bodens aufgrund einer Temperatur-Beanspruchung vorzubeugen. All dies wird erzielt bei zugleich höheren Festigkeitswerten für die Verklebung. Für Datenträger sind Testmodelle im Einsatz, bei denen aufgrund von vielfach wiederholtem Biegen geprüft wird, ob und wann Beschädigungen auftreten, insbesondere an der Verklebung des Moduls. Und trotz der geringeren Klebfo liendicke, wie sie erfindungsgemäß eingesetzt wird, stellt sich heraus, daß die Verklebung standfester ist als dies mit bisher bekannten Mitteln erreichbar war.The advantages achieved according to the invention are in particular in that less deformation of the back of the Data carrier takes place and that higher cycle times due to a faster activation can be achieved. In addition, it will possible to reduce the overall thickness of the module, which at is a considerable advantage to modern data carriers and to reduce the milling depth for the mounting of the IC module gladly and thus a deformation of the disk bottom to prevent due to temperature stress. All this is achieved with higher strength values for the Bonding. Test models are used for data carriers, at those tested due to repeated bending will determine whether and when damage occurs, in particular gluing the module. And despite the lower adhesive Line thickness, as used according to the invention out that the bond is more stable than this with previously known means was achievable.
Im folgenden soll die Erfindung beispielhaft beschrieben werden.The invention is described below by way of example become.
In einem leistungsfähigen Schnellrührwerk werden 1,065 kg Zinkoxyd mit 0,960 kg Vinylchlorid-Polymerisat und 12,0 kg Butanon gut gemischt und in einen Kneter vorgelegt. Es werden 21,98 kg Nitrilkautschuk, weitere 20 kg Butanon und 4,32 kg Phenolharz unter Kneten zugegeben, gefolgt von weiteren 4,0 kg Butanon und 19,2 kg Phenolharz (gepulvert, Occidental Chem.). Es wird gut geknetet, und schließlich werden weitere 44,2 kg Butanon zur Endverdünnung in 3 Portionen zugegeben.In a powerful high-speed agitator, 1.065 kg Zinc oxide with 0.960 kg vinyl chloride polymer and 12.0 kg butanone well mixed and in one Kneader submitted. There are 21.98 kg of nitrile rubber, another 20 kg butanone and 4.32 kg Phenolic resin added with kneading, followed by another 4.0 kg butanone and 19.2 kg phenolic resin (powdered, Occidental Chem.). It is kneaded well, and finally another 44.2 kg of butanone are used for final dilution added in 3 portions.
Die Masse wird mittels Streichbalken auf ein siliconisiertes Trennpapier ausgestrichen und zu einer Klebfolie von 30 µm getrocknet.The mass is siliconized using a coating bar Spread the release paper and form an adhesive film of 30 µm dried.
Wie in EP-A 493.738 beschrieben, werden Stanzlinge dieser Folie zum Verkleben von Trägerelementen in Datenträger ein gesetzt. Der Klebeverbund wird heiß verpreßt derart, daß der Stanzling der Klebfolie auf eine Temperatur von 100°C aufge heizt wird. Die erhaltenen Datenträger sind ohne Ausschuß und weisen einen hochfesten und dauerhaften Verbund auf.As described in EP-A 493.738, die cuts become these Film for gluing carrier elements into data carriers set. The adhesive bond is hot pressed in such a way that the Die cut the adhesive film to a temperature of 100 ° C is heated. The data media received are without rejects and have a high-strength and durable bond.
