Definitions
- At least one coil is present in the chip card. This coil is either the secondary winding of a transformer at a short distance from the terminal or an antenna at a greater distance.
- the coil diameter is chosen to be as large as possible, so that the coil runs close to the outer contour of the chip card.
- the coil is arranged on a carrier that the
- Coil on the one hand gives greater mechanical stability and on the other hand should serve better transportability.
- the semiconductor chip to be connected to the coil is also arranged on this carrier.
- the coil can either be a wound wire coil or a planar coil applied, for example, using thick-film technology or by etching a copper layer.
- the carrier is usually realized with a film, preferably with a flexible plastic film, and together with the coil, the semiconductor chip and possibly other connecting parts, such as a leadframe carrying the semiconductor chip, represents a carrier element or an inlay that is laminated or encapsulated in a chip card, to result in a chip card after any further processing steps.
- the individual layers are usually larger than the final card size, the final card being produced by punching out after the lamination.
- the ticker therefore has the same dimensions as the card.
- the object of the present invention is therefore to provide a carrier element for installation in a chip card which is suitable for different card materials in the same way and thereby ensures good mechanical stability of the card.
- the carrier element can be used to form a chip card surrounding materials come into good contact with one another and thus ensure sufficient mechanical stability without the support element having to be made of the same material as the rest of the card.
- the molding compound does not have to be injected into the injection mold on both sides of the carrier element, as would be the case with the known films, which, given the low thickness of the card, entails considerable injection-molding problems would bring.
- the injection molding material can be distributed as desired in the injection mold, which also increases the injection speed and thus the manufacturing time of a card can be reduced.
- a planar coil 2 is applied to a carrier film 1, for example by means of thick-film technology.
- the ends 3, 4 of the coil 2 extend over a somewhat longer area spaced from the coil 2.
- Two areas A, B are identified by dots, which are intended to indicate that a semiconductor chip (not shown) can be connected to the coil at different points.
- the carrier film 1 has inner recesses 5 in the inner region of the coils, so that only one supporting structure remains.
- the carrier film 1 has outer recesses 6.
- the outer contour of the standardized chip card is indicated by a dashed line 7, this outer contour being intended to run within the outer recesses 6, so that a good connection of the card material on the outer edge of the card is guaranteed.
- the remaining thin webs 8 of the carrier film 1 do not interfere with the mechanical stability of the card.
