Den foreliggende oppfinnelse vedrører en fremgangsmåte for kontinuerlig fremstilling av mikromoduler for kort som in-neholder komponenter av typen CCC. Oppfinnelsen vedrører også produkter som er fremkommet i henhold til fremgangsmåten, et kontinuerlig bånd av micromoduler og en micromodul. Oppfinnelsen finner anvendelse innen området for fremstilling av de nevnte komponenter for kort av den ty-pe som brukes for elektronisk betaling, eller også sik-kerhetskort . The present invention relates to a method for the continuous production of micromodules for cards containing components of the CCC type. The invention also relates to products produced according to the method, a continuous band of micromodules and a micromodule. The invention finds application in the area of manufacturing the aforementioned components for cards of the type used for electronic payment, or also security cards.
Oppfinnelsen skaffer det særtrekk å overføre til området for fremstilling av micromoduler, den fremgangsmåte for fabrikasjon på kinofilmer, som allerede er utviklet på andre områder. Overføringen av denne fremgangsmåte til området for micromoduler for kort av typen CCC, innebæ-rer modifikasjoner forsåvidt som disse gjelder nivået for fremstillingen såvel som produktene som fremskaf- The invention provides the distinctive feature of transferring to the area of manufacturing micromodules, the method for manufacturing cinema films, which has already been developed in other areas. The transfer of this method to the area of micromodules for cards of the CCC type involves modifications insofar as these apply to the level of production as well as the products that provide
fes ved fremgangsmåten.fes by the procedure.
Man vet at på fabrikasjonsnivået for slike komponenter, blir der for hver serie fastsatt et stort antall. Re-duksjonene av kostnadene for fremstillingen av hver en-het, er derfor av største viktighet. It is known that at the manufacturing level for such components, a large number is determined for each series. The reductions in the costs for the production of each unit are therefore of the greatest importance.
Ifølge kjent teknikk har man fremstilt micromodulkompo-nenter hovedsakelig av et kort av typen CCC. Et slikt kort omfatter i det minste en micromodul som er montert i det indre av et plastisk underlag som utgjør selve kortet. Micromodulen bærer som en generell regel, en microkrets som er plassert på ledende felter som reali-serer en forbindelse av utgangene fra microkretsen til kontakter som er innrettet til å bli lest av en bruker av kortet CCC. Forbindelsestrådene er således forbund- According to known technology, micromodule components have been produced mainly from a card of the CCC type. Such a card comprises at least one micromodule which is mounted in the interior of a plastic substrate which makes up the card itself. The micromodule carries, as a general rule, a microcircuit which is placed on conductive fields which realizes a connection of the outputs from the microcircuit to contacts which are arranged to be read by a user of the card CCC. The connecting threads are thus connected
et med hver utgang fra microkretsen ved en sone for forhåndsbestemt kontakt. Sammenstillingen er anordnet i en kapsel av harpiks som tillater beskyttelse av micromodulen, og gir denne en viss mekanisk stivhet. one with each output from the microcircuit at a zone of predetermined contact. The assembly is arranged in a capsule of resin which allows protection of the micromodule, and gives it a certain mechanical rigidity.
Den foreliggende oppfinnelse vedrører en kontinuerlig fremstilling av micromoduler for kort som omfatter komponenter av typen CCC. Den er kjennetegnet spesielt ved følgende trinn: - å tilkappe på et kontinuerlig metallbånd suksessive ledende celler, idet hver celle fastholdes til båndet ved hjelp av smale metalliske partier, spesielt på ni-vå for kontaktene, å plassere en plastfilm på en første side av det ledende bånd, - å fiksere på et sentralt ledende felt av hver celle på en annen flate, i det minste en microkrets som er forbundet med kontakter for ledetrådene, The present invention relates to a continuous production of micromodules for cards comprising components of the CCC type. It is characterized in particular by the following steps: - covering successive conductive cells on a continuous metal strip, each cell being fixed to the strip by means of narrow metallic parts, especially at the level of the contacts, to place a plastic film on a first side of the conductive tape, - to fix on a central conductive field of each cell on a different surface, at least one microcircuit which is connected with contacts for the conductive wires,
å plassere på den annen flate av det ledende båndto place on the other surface of the conductive tape
i det minste lokalt over microkretsene, en beskyttelsesharpiks, at least locally above the microcircuits, a protective resin,
å separere ved kapping hver micromodul fra sin nabomodul. to separate each micromodule from its neighboring module by cutting.
Den foreliggende oppfinnelse vedrører også et kontinuerlig bånd av micromoduler som er fremskaffet i henhold til den foreliggende fremgangsmåte. Et slikt bånd omfatter et første lag som utgjøres av en plastfilm for beskyttelse av kontaktene hos micromodul-sammenstillingene, et annet ledende lag som omfatter en ledende celle av kontakter for hver micromodul, og elementer som fastholder hver micromodul til sin nabomodul, et tredje lag som utgjøres av en beskyttelsesharpiks, The present invention also relates to a continuous band of micromodules which have been produced according to the present method. Such a tape comprises a first layer which is formed by a plastic film for protecting the contacts of the micromodule assemblies, a second conductive layer which comprises a conductive cell of contacts for each micromodule, and elements which hold each micromodule to its neighboring module, a third layer which consists of a protective resin,
idet i det minste en mikrokrets er blitt plassert på hver celle med forbindelsestrådene i kontakt før avsetningen av det tredje lag. at least one microcircuit having been placed on each cell with the connecting wires in contact prior to the deposition of the third layer.
Oppfinnelsen vedrører også en mikromodul som er ut- skåret fra et bånd av micromoduler i henhold til oppfinnelsen. En slik mikromodul omfatter en plastisk beskyttelsesfilm som kan fjernes i det minste lokalt i området for kontaktene, en ledende celle som utgjøres av kontaktene, og et underlag for i det minste en microkrets som er forbundet ved hjelp av de elektriske trådforbind-elser med kontakter, og en ledende harpikskapsel i det minste parallellt med flaten av den celle som bærer microkretsen . The invention also relates to a micromodule which is cut from a band of micromodules according to the invention. Such a micromodule comprises a plastic protective film which can be removed at least locally in the area of the contacts, a conductive cell which is constituted by the contacts, and a substrate for at least one microcircuit which is connected by means of the electrical wire connections with contacts, and a conductive resin capsule at least parallel to the surface of the cell carrying the microcircuit.
Andre egenskaper og fordeler med den foreliggende oppfinnelse vil fremgå i det følgende ved hjelp av beskriv-elsen av de vedføyde tegningsfigurer. Figur 1 er et skjematisk riss gjennom en micromodul i henhold til oppfinnelsen. Figur 2 er et utsnitt av et kontinuerlig bånd fremskaffet i henhold til oppfinnelsen. Figur 3 viser en variant av en utførelsesform for oppfinnelsen. Other properties and advantages of the present invention will be apparent in the following with the help of the description of the attached drawings. Figure 1 is a schematic view through a micromodule according to the invention. Figure 2 is a section of a continuous belt produced according to the invention. Figure 3 shows a variant of an embodiment of the invention.
På figur 1 er der vist en micromodul 1 i henhold til oppfinnelsen. En slik micromodul omfatter tre suksessive lag. Et første lag 1 utgjøres av en plastfilm for beskyttelse av micromodul-kontaktene. Et annet lag 2 utgjøres av en ledende celle som er sammensatt av kontakter, f.eks. kontaktene 8 og 9, og et sentralt ledende felt 10. Figure 1 shows a micromodule 1 according to the invention. Such a micromodule comprises three successive layers. A first layer 1 consists of a plastic film to protect the micromodul contacts. Another layer 2 is made up of a conductive cell which is composed of contacts, e.g. contacts 8 and 9, and a central conducting field 10.
På det sentrale ledende felt 10 er der anordnet en microkrets 4, f.eks. et leselager. Ved en utførelses-form er leselageret 4 festet på feltet 10 ved hjelp av et ledende klebemiddellag 5. Koblingstrådene, f.eks. trådene 6, 7 utgjør den elektriske forbindelse som knytter lageret til kontaktene 8, 9. Sluttelig fore-ligger der et tredje lag 3 som utgjøres av en beskyt tende harpiks som dekker det øvre lag av micromodulen på figuren. A microcircuit 4 is arranged on the central conductive field 10, e.g. a reading warehouse. In one embodiment, the read bearing 4 is attached to the field 10 by means of a conductive adhesive layer 5. The connecting wires, e.g. the wires 6, 7 form the electrical connection that connects the bearing to the contacts 8, 9. Finally, there is a third layer 3 which is made up of a protective resin that covers the upper layer of the micromodule in the figure.
For å tillate bruken av micromodulen, f.eks. i et kort av typen CCC, blir den plastiske beskyttelsesfilm igjen truk-ket av den underste harde flate av det ledende lag 2. Ved en utførelsesform som ikke er representert på tegnings-figurene, kan de samme partier av den beskyttende film 1 som skal fjernes, kunne utgjøres av filmpartier i området for kontaktene 8, 9. En slik realisering tillater konservering av en overfladisk beskyttelse av de ledende partier på den flate som ligger under micromodulen på konstruksjonen. To allow the use of the micromodule, e.g. in a card of the CCC type, the plastic protective film is again pulled from the lower hard surface of the conductive layer 2. In an embodiment that is not represented in the drawing figures, the same parts of the protective film 1 that are to be removed can , could be made up of film parts in the area of the contacts 8, 9. Such a realization allows the preservation of a superficial protection of the conductive parts on the surface which lies below the micromodule on the structure.
Ved et eksempel på utførelsesform kan tykkelsen av en micromodul være begrenset til ca. 600 micrometer. Det ledende lag utgjøres av et metallbånd med tykkelse 100 micrometer. Der benyttes et ledende limskikt på 20 micrometer, og dessuten 275 micrometer for leselageret. In an exemplary embodiment, the thickness of a micromodule can be limited to approx. 600 micrometres. The conductive layer consists of a metal strip with a thickness of 100 micrometres. A conductive adhesive layer of 20 micrometers is used, and also 275 micrometers for the read bearing.
De ledende tråder har en diameter i størrelsesordenThe conducting wires have a diameter in the order of magnitude
25 micrometer, og der benyttes 50 micrometer som ut-25 micrometer, and 50 micrometer is used as output

I forbindelse med figur 2 vil det bli forklart hvordan fremgangsmåten ifølge oppfinnelsen kommer til anvendelse ved et eksempel på utførelsesform. På figur 2 er der vist et lengdeutsnitt av et kontinuerlig bånd 20. Hen-visningstallene 25 - 28 gir her anvisning på sirkulære gjennombrytninger som tillater identifikasjon av en skrittfase på båndet, svarende til en ledende celle. In connection with Figure 2, it will be explained how the method according to the invention is used in an example embodiment. Figure 2 shows a longitudinal section of a continuous band 20. The reference numerals 25 - 28 here indicate circular openings which allow the identification of a step phase on the band, corresponding to a conducting cell.
På figur 2 er der i den hensikt å fordoble avkastning-In figure 2, with the intention of doubling the return-

Med hensyn til delene som inngår i konstruksjonen, noe som ikke er vist på figur 2, er nabo-micromodulene 29, 30, fremstilt på samme måte. På fi- one by the method, done so for the normalization of the micromodules, to fabricate two micromodules 29, 30 in parallel. With regard to the parts included in the construction, which is not shown in Figure 2, the neighboring micromodules 29, 30 are produced in the same way. On fi-
gur 2 har man hovedsakelig vist detaljene ved det øvre av micromodulen. Der er anordnet åtte kontakter C1-C8 Figure 2 mainly shows the details of the upper part of the micromodule. There are eight contacts C1-C8
som fremskaffes ved en passende utskjæring av det kontinuerlige bånd 24. En slik utskjæring kan realiseres f. eks. ved stansing eller ved fotogravering. Spesielt med hensyn til fotogravering, vil det kontinerlige bånd 1 være fremstilt av en plastfilm hvor en side er metalli-sert. which is obtained by a suitable cut-out of the continuous band 24. Such a cut-out can be realized, e.g. by punching or by photogravure. Especially with regard to photoengraving, the continuous band 1 will be produced from a plastic film where one side is metallised.
Den micromodul som er fabrikert på cellen 29, bærer et sentralt ledende felt Sl som står i direkte forbindel- The micromodule that is fabricated on the cell 29 carries a central conducting field Sl which is in direct connection

en microkrets, f.eks. microkretsen 4. Den micromodul som skal fremskaffes på halvledercellen 29, er forbundet på den ene side ved hjelp av det kontinerlige bånd 20 ved hjelp av de sidepartier som ikke er avmerket, a microcircuit, e.g. the microcircuit 4. The micromodule to be provided on the semiconductor cell 29 is connected on one side by means of the continuous band 20 by means of the side parts that are not marked,
og ved hjelp av de smale partier, f.eks. partiet 23,and using the narrow parts, e.g. lot 23,
som er fremskaffet ved utskjæringer, f.eks. utskjæringene 21 eller 22 i det ledende bånd. which is obtained by cuttings, e.g. the cutouts 21 or 22 in the conductive band.
Ved fremgangsmåten ifølge oppfinnelsen plasserer man deretter microkretsen på feltet Sl, man plasserer forbindelsestrådene ved hjelp av lodding, spesielt ultra-lyd, hvoretter man dekker i det minste delvis i sonen 31 microkretsen på den ledende celle 29 ved hjelp av en beskyttelsesharpiks. In the method according to the invention, the microcircuit is then placed on the field Sl, the connecting wires are placed using soldering, especially ultrasound, after which the microcircuit is at least partially covered in the zone 31 on the conductive cell 29 using a protective resin.
Operasjonen er lik det skritt som utføres i forbindelse med den ledende celle 30. Det gjentas for hvert skritt som båndet forskyves på en maskin under bruk av et indeksseringsorgan. The operation is similar to the step performed in connection with the conductive cell 30. It is repeated for each step that the tape is moved on a machine using an indexing means.
Ifølge oppfinnelsen fremskaffes micromodulen ved opp-skjæring av båndet ved hjelp av utskjæring av trange partier av den innbyrdes forbindelse mellom micromodulene. Fordi den beskyttende harpiks på en sammen- hengende måte holder tilbake sammenstillingen på båndet, blir utskjæringen realisert på tvers av aksen for det kontinuerlige bånd, nemlig i området for utskjæringene 21 og 22. De ytterligere avskjæringer i lengderetning- According to the invention, the micromodule is obtained by cutting up the tape by means of cutting out narrow parts of the mutual connection between the micromodules. Because the protective resin coherently holds back the assembly on the strip, the cutout is realized across the axis of the continuous strip, namely in the region of the cutouts 21 and 22. The further longitudinal cutouts-
en over kontaktene Cl og C8 på modulen 29, og under re-siproke kontakter C4, C5 for cellen 30, blir realisert for å tillate utvinning av hver av micromodulene fra det kontinuerlige bånd. one above the contacts C1 and C8 of the module 29, and below the reciprocal contacts C4, C5 of the cell 30, is realized to allow the extraction of each of the micromodules from the continuous tape.
Beskyttelsesbåndet 1 som er anordnet på den nedre flate, kan sløyfes enten ved installasjonen av micromodulen ved den ferdige produksjon, eller etter fremskaffelsen av det kontinuerlige bånd for micromodulen. Dens rolle begrens-er seg til en beskyttelse av kontaktene under fremstillingen av micromodulene for å unngå at den omtalte harpiks ikke passerer fra den annen flate av den ledende celle som microkretsen er plassert på, mot den første flate som kontaktene blir lest på. The protective tape 1, which is arranged on the lower surface, can be looped either during the installation of the micromodule at the finished production, or after the procurement of the continuous tape for the micromodule. Its role is limited to a protection of the contacts during the manufacture of the micromodules to prevent the mentioned resin from passing from the second surface of the conductive cell on which the microcircuit is placed, towards the first surface on which the contacts are read.
På figur 3 er der vist et riss over en variant av ut-førelsesform for oppfinnelsen. På båndet er de forskjellige kontakter Cl - C8 representert delvis rundt en sen-tral ledende sone. Microkretsen 60 er plassert på et cellelag 61. Forbindelsestrådene fra mikrokretsen er på figuren vist ved forskjellige kontakter. Der er og- Figure 3 shows a diagram of a variant embodiment of the invention. On the tape, the various contacts Cl - C8 are represented partially around a central conductive zone. The microcircuit 60 is placed on a cell layer 61. The connection wires from the microcircuit are shown in the figure by different contacts. There are and-
så vist en sone 56 for avsetning av beskyttelsesharpiks som utgjør beskyttelseskapselen for micromodulen. so shown is a zone 56 for the deposition of protective resin which constitutes the protective capsule for the micromodule.
Ifølge denne variant, er der for hver kontakt anordnet knaster 40 - 45, som er dreiet mot det indre av harpikskapselen på en måte som forsterker vedheftelsen av harpiksen på den ledende celle. Ifølge en egenskap hos harpiksen, kan der anordnes forskjellige orienteringer av knastene. Spesielt kan knastene danne en spiss vink-el i forhold til den ledende celles plan. Ved sin kon-truksjon og ifølge en foretrukken utførelsesform kan alle knastene være plassert i en retning vinkelrett på planet for den ledende celle. According to this variant, lugs 40 - 45 are arranged for each contact, which are turned towards the interior of the resin capsule in a way that reinforces the adhesion of the resin to the conductive cell. According to a property of the resin, different orientations of the knobs can be arranged. In particular, the knobs can form an acute angle in relation to the plane of the conducting cell. By its construction and according to a preferred embodiment, all the knobs can be located in a direction perpendicular to the plane of the conductive cell.
Som en variant kan de kontinuerlige bånd bære andre in-dekseringsorganer enn dem som er vist på figur 2. Spesielt kan de være anordnet for dannelse av spalter ved begynnelsen og slutten av hvert bånd. As a variant, the continuous bands may carry other indexing means than those shown in figure 2. In particular, they may be arranged to form slits at the beginning and end of each band.
Ved en foretrukken utførelsesform vil man før påføring-en av den beskyttende harpiks, fremskaffe en avsetning av en ledende film som beskytter den annen flate av det ledende, metallbånd mot kjemiske stoffer. F.eks. kan der velges gull. In a preferred embodiment, before the application of the protective resin, a deposit of a conductive film is produced which protects the other surface of the conductive metal tape against chemical substances. E.g. gold can be chosen.
