Definitions
- the invention relates to an electrically conductive connection between an integrated circuit designed as a chip and a coupling element for transmitting data and / or energy from and / or to the chip.
- the invention relates equally to documents of value, in particular banknotes, and security paper for the production of these documents of value and security elements for application or introduction to or into the security paper, each of which has such an electrically conductive connection between the chip and the associated coupling element.
- the invention relates to a method for capacitive
- Documents of value in the sense of the present invention can be banknotes, certificates but also credit cards and the like.
- the invention is particularly suitable for use in thin, paper documents of value such as banknotes, but can also be used in connection with other documents of value.
- the application of integrated circuits in the form of chips in or on banknotes is proposed, for example, in EP 0 905 657 A1 in order to increase the security of banknotes against counterfeiting by means of information stored in the chip.
- the chip is a transponder chip, which is therefore not contacted directly by external data processing devices, but in which the
- Data exchange takes place via a coupling element designed as an open or closed dipole antenna, for which purpose, for example, the security thread contained in the banknote or one separately in the banknote provided, closed coil can serve.
- a coupling element designed as an open or closed dipole antenna, for which purpose, for example, the security thread contained in the banknote or one separately in the banknote provided, closed coil can serve.
- Chip contact elements is proposed in connection with chip cards in EP-A-512 546 and DE 19957609 AI to use anisotropic conductive adhesive, that is, only in one direction, namely between the chip and. , Contact element, are conductive.
- anisotropic conductive adhesive that is, only in one direction, namely between the chip and. , Contact element, are conductive.
- Such an anisotropic adhesive layer can cover all contact elements together without this leading to
- DE 19957609 AI proposes to provide spherical, possibly elastic guide bodies next to one another and spaced apart from one another in a manageable, compressible heat seal adhesive layer.
- pressure and temperature are used to ensure that the spherical guide bodies form an electrically conductive connection between the contact elements of the chip and the coupling element, but the guide bodies do not come into contact with one another, so that a Short circuit formation avoided becomes.
- DE 199 57609 AI does not contain specific information about the elastic guide bodies.
- the object of the present invention is therefore to propose an electrically conductive connection with which chips and associated coupling elements can be reliably connected to one another, in particular in connection with securities.
- the solutions according to the invention are based on the knowledge that the electrically conductive connection between the chip and the coupling element should generate as little mechanical stress as possible in the break-prone chip, in particular not at the time of the chip application.
- this finding is implemented in order to achieve the aforementioned object in such a way that the adhesive connecting the chip and the coupling element is an anisotropic conductive adhesive which contains electrically conductive particles, the maximum size of which is smaller than the distance between the chip and the Coupling element, preferably less than 1 mm.
- These particles are preferably aligned in the adhesive, for example in a magnetic field, so that they only conduct in the direction between the chip and the coupling element and are otherwise isolated from one another by the adhesive material. With an adhesive layer thickness of approximately 2 .mu.m, it is thus ensured that the particles cannot exert mechanical stresses on the chip due to their small size.
- an anisotropic adhesive with electrically conductive particles is also used, which, however, consist of a solder material that is soft at an elevated temperature at which the chip is connected to the coupling element. After cooling, the solder material solidifies in the form it was in when the chip was applied. This ensures that, in particular when applying the chip, there are no mechanical voltages from the electrical. conductive particles are exerted on the chip.
- the solder material particles are arranged in a suitable adhesive matrix next to one another and spaced apart from one another such that they are still spaced apart from one another after application of the chip.
- a third embodiment of the invention provides a capacitive coupling.
- This embodiment is suitable for use with high-frequency alternating currents of, for example, approximately 2 GHz. Any conductive particles in the adhesive layer that promote mechanical stresses can be dispensed with. Instead, the adhesive layer forms a thin, dielectric layer between the chip contact surfaces and the coupling element.
- the energy supply for the chip takes place via an alternating field which is capacitively coupled into the chip, and the chip has a rectifier and a capacitor for energy storage.
- Figure 2 shows an electrically conductive connection with anisotropic adhesive according to the second embodiment of the invention
- Figure 3 shows an electrically conductive connection with capacitive coupling according to the third embodiment of the invention.
- FIG. 1 shows a substrate 1 with a coupling element 2 and an integrated circuit 3 which is electrically conductively connected to the coupling element 2 via an adhesive 4.
- the substrate 1 can be a security, in particular a bank note, or also a preliminary product of such a security, namely a security paper, which is processed into a security only later.
- the substrate 1 can also be other documents of value, for example a chip card.
- the substrate 1 can also be a security element, for example an optically variable element (OVD) or a security thread, which are only later connected to a value document or security paper.
- ODD optically variable element
- the security element would preferably be attached to the value document in such a way that the optically variable side of the OVD points outwards and the OVD obscures the view of the integrated circuit 3.
- the coupling element 2 can simultaneously serve as a reflection layer in order to reflect the light passing through the optically variable element.
- the invention is preferably used in securities such as banknotes.
- the substrate 1 and the coupling element 2 preferably form a security thread therein, the substrate 1 being, for example, a transparent plastic, on which the coupling element 2 as
- the coupling element 2 then represents an open dipole, via which data and / or energy can be transmitted contactlessly from an external device to the integrated circuit .3.
- the chip 3 can also be applied to another substrate or security element and connected to the banknote, it then being possible, depending on the available area, to design the coupling element 2 as a closed dipole or as a coil.
- a laminating film which is not shown in the figure, can be arranged.
- the integrated circuit is available as a manageable chip before it is applied. This can be, for example, a pure memory chip (ROM), a rewritable chip (EPROM, EEPROM) or a microprocessor chip.
- the chips used have a thickness of 5 mm to 50 mm, preferably 10 mm, and an edge length of approximately 0.1 mm to 3 mm, preferably 0.6 mm. There are preferably two to four contact areas 5 on the chip 3.
- the adhesive 4 by means of which the chip 3 and the coupling element 2 are firmly connected to one another, contains electrically conductive particles 6.
- the maximum size is this
- the distance between the contact surfaces 5 and the coupling element 2 is preferably approximately 2 mm and the maximum particle size is therefore less than approximately 1 mm, preferably approximately 0.5 mm.
- the particles 5 are aligned before the adhesive 4 is crosslinked to such an extent that the particles 6 are aligned in them Location are largely fixed.
- the alignment of the particles 6 can take place, for example, in a magnetic field, so that adjacent particles 6 collide and form lines in the preferred electrical direction.
- the conductive powder sold by DuPont under the trade name "ZELEC ECP-3010XC” has proven to be a suitable material for the conductive particles 6.
- Silver nanopowder with a particle size of preferably about 0.5 ⁇ m is also suitable.
- the choice of adhesive is also not insignificant. It must be protected against mechanical overload and therefore be flexible within limits. With a layer thickness of 2 mm, the ohmic volume resistance should be about 5 ohms. Furthermore, it must be ensured that the small contact areas 5 of the chip 3, each with a size of approximately 70 mm ⁇ 70 mm, are sufficiently contacted. In particular, contacting of aluminum layers with an oxide coating must be ensured, since the contact of the coupling element 2 with the air causes a natural oxidation of the aluminum. Finally, it must be ensured that the electrical conductivity of the adhesive in the HF field does not extend further than 100 mm against the preferred direction. The distance between adjacent contact areas of the coupling element 2 is approximately 100 mm.
- the electrically conductive particles 6 of the anisotropic adhesive 4 consist of a solder material, for example tin bismuth.
- the chip 3 is usually placed on the coupling element 2 using hot stamping technology, the temperature introduced causing the adhesive 4 to soften and crosslink and the slight pressure to contact the chip 3 with the connection areas of the coupling element 2.
- the temperature of the hot stamp and the softening temperature of the solder material are coordinated with one another such that the solder material softens when the chip 3 is applied and adapts to the contact surfaces 5 in accordance with the shape of the pressure of the hot stamp.
- the electrically conductive solder material particles When applying of the chip 3 on the coupling element 2, the electrically conductive solder material particles therefore do not exert any significant stresses on the chip 3, but deform plastically, but ensure an electrically conductive connection between the contact surfaces 5 of the chip 3 and the coupling element 2.
- the solder particles 6 are distributed in a matrix-like manner in the adhesive 4, so that they are not in cross-connection with one another, not even after the application of the chip, as described in DE 199 57509 A1.
- the adhesive sold under the name “Loctite 3440” has proven to be a suitable adhesive in connection with the solder material particles.
- an adhesive 4 which does not necessarily contain electrically conductive particles.
- the transmission of data and / or energy takes place capacitively between the coupling element 2 and the contact areas 5 of the chip 3.
- This type of transmission is particularly suitable at high frequencies of, for example, 2 GHz for energy transmission, the data stream, for example, with a frequency of approx. 400 MHz is modulated.
- the slight distance between the contact surfaces 5 and the respectively immediately adjacent sections of the coupling element 2 acts as a short circuit. There is no need for ohmic contacting.
- the chip has a capacitor and a voltage rectifier to charge the capacitor energetically via a capacitively coupled alternating field.
- the adhesive 4 acts between the coupling element 2 and the contact connections 5 as a dielectric. For capacitive coupling it is also necessary to enlarge the connection areas of the integrated circuit
