Definitions
- the present invention relates to a chip module for chip cards.
- Chip cards such as B. Multimedia cards or smart cards consist of a plastic card body and a semiconductor chip inserted therein.
- This semiconductor chip can be used as a chip module in which the actual chip is attached to a chip carrier with which it is inserted into a recess in the card body.
- the chip carrier can in particular also have connection contacts for external connection to a reading device.
- the chip carrier has a fastening area on which the semiconductor chip is attached and is usually covered with a sealing compound. Around this potting compound there is a protruding fastening edge of the chip carrier, which is glued to a fastening edge of the recess of the card body provided for the chip, which is slightly set back from the top of the card body.
- connection between the chip carrier and the card body is preferably made by means of adhesive.
- Cold adhesives which are processed at room temperature, or hot adhesives, in which the adhesive bond is produced at higher temperatures and, if appropriate, increased contact pressure, are used.
- the chip carrier should have sufficient mechanical stability; therefore a thickness of the chip carrier of at least 100 ⁇ m is preferred.
- the surfaces of the mounting edge of the chip carrier and the mounting edge of the recess in the card body should be such that they ensure the best possible adhesion of the adhesive as connecting surfaces. Good adhesion of the adhesive is improved by a roughened connection surface.
- An epoxy resin-bonded glass fiber fabric is particularly suitable as a carrier material. If cheaper materials and a smaller thickness of the chip carrier are used, problems arise for the stability of the adhesive bond.
- the actual implantation process, in which the chip module is glued into the card body, is particularly critical. High temperatures and high contact pressure can deform the material of the chip carrier.
- the object of the present invention is to provide a cost-effective embodiment of a chip module for chip cards, with which a sufficiently permanent adhesive connection is achieved in the card body.
- the chip carrier In the area of the connection point between the chip module and the card body, the chip carrier is provided with a layer which is provided as a reinforcement and optionally structured. In the area of the connection of the chip module to the card body, this enables a selective adaptation of the mechanical properties and the surface properties of the
- Chip carrier to the mounting edge of the card body.
- the layer on the mounting edge of the chip carrier can in particular be a metallization applied there on the side of the chip carrier facing the card body.
- Such a metallization can be provided in addition to the electrical contacting of the semiconductor chip.
- the chip carrier can be metallized on one or both sides, e.g. B. by an applied and structured copper layer with a possibly applied nickel / gold refinement.
- FIGS. 1 to 5 show plan views, Figures 2 and 5 cross sections through exemplary embodiments.
- FIG. 1 shows a top view of a chip module in which a semiconductor chip is fastened on a chip carrier 1 in a central area and is injected and encapsulated in a potting compound 6 as a casing or housing.
- a potting compound 6 as a casing or housing.
- the type and design of the chip and the housing are arbitrary.
- Chip module is provided in a card body is provided with a reinforcement 3, which is applied as a layer.
- a reinforcement 3 On the right side of FIG. 1 there is an enlarged section of the marked rectangular section. A part of the chip carrier 1 is shown there between a portion of the sealing compound 6 and the reinforcement 3, which covers the fastening edge 5 here.
- FIG. 2 shows a cross section through a chip card, from which it can be seen how the chip module is inserted into the
- the chip module comprises a chip carrier 1 with the semiconductor chip 2 applied thereon, which is injected into the sealing compound 6.
- the mounting edge 5 which is provided with the reinforcement 3.
- the chip module is glued to the fastening edge of a recess in the card body 7 using an adhesive layer 4.
- the side of the chip carrier 1 facing away from the semiconductor chip 2 is provided with a layer 10, which can be a cover or a contact layer.
- FIG. 3 shows an enlarged section of the rectangularly marked section on the right-hand side, in which the serrated edge 8 of the reinforcement 3 can be clearly seen in this example.
- FIG. 4 A further advantageous embodiment is shown in FIG. 4.
- the reinforcement 9 is structured in such a way that it is interrupted several times along the fastening edge 5.
- the layer applied for reinforcement must namely have good adhesion properties towards the adhesive layer 4. If the adhesion properties of the surface of the reinforcement 3 are not yet sufficiently good for this, structuring can result in an improvement.
- the structuring increases the surface area before the connection to the adhesive layer 4, which can significantly improve the adhesiveness.
- the structuring is preferably carried out by means of a photo technique and a subsequent etching step. Undercuts that occur are particularly desirable. Such an undercut leads to the layer provided as reinforcement 9 having portions whose lateral dimension, at least in one direction, is smaller directly on the chip carrier 1 than on a surface of the reinforcement 9 which is at a distance from the chip carrier.
- the reinforcement is applied to this Interlocked with the adhesive layer 4.
- FIG. 4 shows, as an example, a structuring of the reinforcement 9 into individual strips oriented transversely to the fastening edge 5.
- FIG. 5 shows in cross section how the good adhesive property comes about in the exemplary embodiment in FIG. It is assumed here that the proportions of the reinforcement 9 have been somewhat undercut.
- the portions of the reinforcement 9 are therefore narrower directly on the chip carrier 1 than on the upper side facing the card body 7.
- the reinforcement 9 rests directly on the card body 7 or at least that there is only an extremely thin adhesive layer between the reinforcement 9 and the card body 7.
- Adhesive layer 4 is essentially only between the portions of the reinforcement 9 and thus brings about the connection between the chip carrier 1 and the card body 7. If there is an undercut of the reinforcement 9, this results in a toothing between the portions of the reinforcement and the portions of the adhesive layer 4 Since the reinforcement 9 is applied to the chip carrier 9, there is a significant improvement, in particular in those cases in which the adhesive of the adhesive layer 4 does not adhere as well to the material of the chip carrier as to the material of the card body, which is usually the case consists of a plastic material.
- the chip card is exposed to mechanical stresses such as torsion and bending changes.
- mechanical stresses such as torsion and bending changes.
