Definitions
- the invention relates to a chip card with a chip card body, in which at least one component can be inserted into at least one cavity, and a method for producing such a chip card.
- Chip cards are already in considerable use today. They are used, for example, as bank cards, telephone cards, access authorization cards, health insurance cards or as SIM or as smart cards.
- the known chip cards are standardized in their dimensions and have a single or multi-layer chip card body, which can contain an internal, electrical circuit. It is known, for example, to accommodate individual electronic components, integrated circuits or voltage sources on a common component carrier, a plastic film, for example, being able to serve as the component carrier. This module carrier can also be provided with the conductor tracks required for the electrical connection.
- a transmitting or receiving unit is integrated into the chip card body, which can consist, for example, of a coil or antenna. Depending on the design, this unit sends or receives signals and thus permits the necessary data transfer.
- Cavities can be introduced into the chip card body, into which components such as integrated circuits (ICs) or so-called chip modules, which consist of a structural unit with contact surfaces and chips, can be inserted.
- ICs integrated circuits
- chip modules which consist of a structural unit with contact surfaces and chips
- DE 199 59 364 A1 discloses a solution according to which, in addition to a first cavity, a further cavity which is spatially separated from the first cavity is introduced into a chip card body.
- DE 197 36 063 A1 also describes that it is possible to subsequently introduce a cavity into the chip card body produced by injection molding. According to the known solution, this is done by a milling process. In addition, the document describes a method according to which the required cavity can be generated during the injection molding process by lowering a displaceable die.
- the invention is based on the technical problem of developing a chip card which is simple in construction and can be produced in a few steps.
- a method for producing such a chip card is to be made available.
- the invention solves this technical problem with the features of claim 1 and with method steps of claim 13.
- a chip card according to the invention accordingly consists of a chip card body in which at least one component can be inserted into at least one cavity, the component being connected to the chip card body to form a flat, inseparable unit by an overlay applied to a surface of the chip card body.
- the chip card is completed with the application of the overlay to a surface of the chip card body. Additional, complex coatings or further injection molding processes are no longer necessary and can be saved.
- the overlay can have a surface with an adhesive layer.
- an overlay makes it possible to complete the chip card in the shortest possible time. It is therefore economical and can be produced in very large numbers without fear of loss of quality.
- the adhesive layer of the overlay can be activated and / or hardened thermally or by means of radiation or by crosslinking. Accordingly, the adhesive layer can be understood not only as an adhesive layer in the classic sense, but as a layer-by-layer application to the overlay, which can be activated or hardened subsequently, that is to say after the overlay has been connected to the chip card body. This subsequent activation or hardening possibility of the adhesive layer enables the chip card to be sealed on the surface, which can be designed free of air inclusions or other undesired foreign body inclusions. This has considerable qualitative advantages in the production of chip cards according to the invention.
- UV radiation is particularly advantageous for activating and / or curing the adhesive layer.
- the overlay In the course of simple processing, it also makes sense to design the overlay as a thin layer or film applied to the chip card body and the component. This can be processed very easily and, with simple manufacturing technology, can be applied without air pockets and foreign bodies. Even vapor deposition of this thin layer or film is within the scope of the inventive concept.
- the layer thickness of the adhesive layer between 5 and 30 ⁇ m, but preferably between 10 and 20 ⁇ m.
- Any electronic component can be understood as a component in the sense of the invention. However, it can also be a chip module, a multi-chip module (MCM) or a battery.
- MCM multi-chip module
- a stiffening frame for the chip card or a security element is also to be understood as a component.
- the connection between the chip card body and the above-mentioned components, which are only listed by way of example, with the overlay to form a one-piece, inseparable component can be provided for each structural unit to be integrated into the chip card.
- the overlay being colored, but preferably white.
- this colored design also makes technical sense. If the overlay is white, for example, the reflective effect of the white color can be used for the use of optoelectronic components, for example to promote or improve data transmissions or to avoid them.
- the white color can also be advantageously used with regard to the ability of the chip card to be illuminated, provided this is necessary for use in external reading devices.
- the overlay with an artwork which, in addition to its aesthetic effect, also has the technical advantage that the chip card can be provided, for example, with a label which individualizes it. This can be of interest, for example, with regard to security against forgery.
- the method according to the invention for producing a chip card is characterized by the following method steps.
- the chip card body is prefabricated. This can be done by injection molding or injection molding with the formation of at least one cavity in the chip card body.
- the electrical lines or contacts required for contacting can also be integrated into the chip card body.
- the overlay can be applied to one of the chip card surfaces, so that the chip card body, the at least one component and the overlay are connected to form an inseparable unit.
- FIG. 1 shows a chip card body in spatial representation as a blank
- Figure 2 shows a chip card body and a chip module in an exploded view in the view corresponding to the arrow direction II of Figure 1 in one
- Figure 3 is the view II of Figure 1 in a second manufacturing stage
- Figure 4 is a sectional view through a chip card in the longitudinal direction in the fully assembled state.
- a chip card according to the invention consists of a chip card body 1, into which several cavities 2 have been introduced during its manufacture.
- This chip card body 1 shown in spatial representation in FIG. 1 can be designed in a manner known per se in one or more layers and can have electrical lines for contacting the individual components which will later be integrated into the chip card body.
- FIG. 1 shows the chip card body 1 shown as a blank in FIG. 1 in a subsequent work step, which can be seen clearly from FIG. 2, which shows the view of a chip card in the direction of arrow II in FIG. 1, by introducing a chip module 3.
- This assembly has various electronic components or contacts 8.
- the components or contacts 8 are located on the underside of the chip module 3 facing the surface 4 of the chip card body 1.
- the electronic ones Components or contacts 8 are inserted into the cavities 2 in the assembly direction illustrated by the arrow A.
- FIG. 3 shows a further production stage of a chip card according to the invention.
- an overlay 5 is applied to the surface 4 of the chip card body 1 beginning on one side of the chip card body 1.
- the beginning of this connection is shown in the right half of the picture.
- the overlay 5 has an adhesive layer 6 on one side. This adhesive layer 6 is consequently located on the underside of the overlay 5 facing the chip card body 1.
- the overlay 5 is applied from the start side in the direction of the other end of the chip card body 1 to its surface 4, which is to avoid air inclusions or foreign bodies, for example by a gentle one Rolling can be done.
- the overlay 5 has a recess 7 in the form of a cutout, the internal dimensions of which correspond approximately to the external dimensions of the component 3. Since the material thickness of the overlay 5 together with the adhesive layer 6 corresponds to the height of the part of the component 3 protruding beyond the chip card body 1, a completely flat surface of the chip card is achieved after the overlay 5 has been completely supported on the chip card body 1.
- the component 3 has freely accessible surface sections, which is of crucial importance, for example, in the case of a chip module for contact-based data transmission.
- FIG. 4 shows a sectional view according to the direction of arrow II from FIG. 1, from which the fully assembled chip card can be removed.
- this chip card consists of a chip card body 1 and an overlay 5 applied thereon, which has a recess 7 through which the component 3 is enclosed.
- the component 3 has a free outer surface.
- the component 3 has electronic components and contacts 8 which engage in the cavities 2 of the chip card body 1. These serve to contact the component 3 through to other components or conductor tracks present on the chip card.
