Abstract

The invention concerns a method for manufacturing a radio frequency identification device (RFID) support (52) featuring an antenna (42) and a double-sided integrated circuit module (10) featuring internal contacts (13, 14) and external contacts (12) connected to a chip (15) encased in a module, the method including the following steps:

• • printing the antenna (42) having contacts (43 and 44) on a support (40),
  • creating a recess (41) between the contacts (43 and 44) of the antenna,
  • pasting a film of glue (110) on the internal face of the module except on the internal contacts (13, 14),
  • positioning the module on the support (40) on the antenna side and so that the internal contacts of the module are against the antenna contacts and the encapsulation (18) of the chip is in the recess,
  • laminating together the support layer (40) and the module so as to connect the module to the antenna and to glue the module.

Claims

1-11. -11. (canceled)

12. A method for manufacturing a radio frequency identification device (RFID) support comprising an antenna and a double-sided integrated circuit module, said integrated circuit comprising internal contacts and external contacts connected to a chip encased in the module, said method including the following steps:

printing an antenna having contacts on a support,

creating a recess between the contacts of said antenna,

pasting a film of glue on an internal face of said module, pierced by two recesses at the location of said internal contacts of the module,

positioning said module on said support on the side of said antenna such that said internal contacts of said module are against said contacts of said antenna and such that the encapsulation of the chip is in said recess,

laminating together said support layer and said module so as to glue the module and connect the module to the antenna by deformation of said antenna contacts that fill said recesses and rest against said internal contacts of the module.

13. A method for manufacturing a hybrid contact-contactless smart card comprising the following steps:

placing a card body on either side of the radio frequency identification device support obtained according to claim 12, said card body located on the side of the antenna being pierced by a recess corresponding to the size of the external contacts of the module,

laminating all layers by applying pressure and heat so as to glue the layers together.

14. The method of claim 12, wherein the film of glue pasted on the module is a non-reversible thermofusible glue.

15. The method of claim 12, wherein the layer of said support is made of a material which does not deform when the temperature increases.

16. The method of claim 12, wherein said antenna is made by screen type printing using conductive ink.

17. The method of claim 13, wherein the card bodies comprise several layers laminated together during the lamination step.

18. The method of claim 13, wherein the card bodies comprise several layers laminated together prior to the lamination step.

19. The method of claim 12, wherein a tool used during the lamination steps comprises a lamination plate provided with a recess in which the external face of the module is placed against said plate and so as to leave the internal contacts of the module visible and accessible.

20. The method of claim 19, wherein said recess has a thickness corresponding to a thickness of the module at the location of the internal contacts.

21. The method of claim 19, wherein the tool used during the lamination steps includes an upper lamination plate provided with protrusions located vertically above contacts of the antenna and recesses in the film of glue during the first lamination step.

22. A method for manufacturing a radio frequency identification device (RFID) support comprising an antenna and a double-sided integrated circuit module, said integrated circuit comprising internal contacts and external contacts connected to a chip encased in the module, said method including the following steps:

printing an antenna having contacts on a support,

creating a recess between the contacts of said antenna,

pasting a film of glue on an internal face of said module, pierced by two recesses at the location of said internal contacts of the module,

positioning said module on said support on the side of said antenna such that said internal contacts of said module are against said contacts of said antenna and such that the encapsulation of the chip is in said recess,

positioning a layer on said antenna support on the side opposite that where the antenna is printed,

laminating together said layer, said support layer and said module so as to glue the module and connect the module to the antenna by deformation of said antenna contacts that fill said recesses and rest against said internal contacts of the module.

23. A method for manufacturing a hybrid contact-contactless smart card comprising the following steps:

placing a card body on either side of the radio frequency identification device support obtained according to claim 22, said card body located on the side of the antenna being pierced by a recess corresponding to the size of the external contacts of the module,

laminating all layers by applying pressure and heat so as to glue the layers together.

24. The method of claim 22, wherein the film of glue pasted on the module is a non-reversible thermofusible glue.

25. The method of claim 22, wherein the layer of said support is made of a material which does not deform when the temperature increases.

26. The method of claim 22, wherein said antenna is made by screen type printing using conductive ink.

27. The method of claim 23, wherein the card bodies comprise several layers laminated together during the lamination step.

28. The method of claim 23, wherein the card bodies comprise several layers laminated together prior to the lamination step.

29. The method of claim 22, wherein a tool used during the lamination steps comprises a lamination plate provided with a recess in which the external face of the module is placed against said plate and so as to leave the internal contacts of the module visible and accessible.

30. The method of claim 29, wherein said recess has a thickness corresponding to the thickness of the module at the location of the internal contacts.

31. The method of claim 29, wherein the tool used during the lamination steps includes an upper lamination plate provided with protrusions located vertically above contacts of the antenna and recesses in the film of glue during the first lamination step.
