Abstract

A method for manufacturing an identity booklet cover provided with a radio frequency identification device having an antenna and a chip (12) connected to the antenna, the method including the following steps:

• • producing an antenna (12) having contacts (13 and 14) on a support (10),
  • creating a recess (20) between the contacts (13 and 14),
  • placing adhesive dielectric material (25, 26) near the contacts of the antenna,
  • positioning an integrated circuit module (19) on the support so that the groups of contacts of the module are opposite the contacts of the antenna and the encapsulation of the module is in the recess (20),
  • placing on the face of the support featuring the antenna at least one layer of thermo-adhesive film (40, 50, 60),
  • placing a cover layer (70) on the layer (or) layer(s) (40 or 50 and 60) of thermo-adhesive film,
  • laminating all the layers.

Claims

1. A method for manufacturing an identity booklet cover provided with a radio frequency identification device (RFID), said device featuring an antenna and a chip connected to the antenna, said method comprising:

manufacturing an antenna having contacts on a antenna support layer made of paper or synthetic paper,

creating a recess between the contacts of the antenna,

placing adhesive dielectric material on the antenna support layer near said antenna contacts, wherein said antenna contacts are U-shaped and the adhesive dielectric material is placed inside the U,

positioning an integrated circuit module on said antenna support layer, said module featuring groups of contacts and the chip connected to groups of contacts inside an encapsulation of the module, so that the groups of contacts of said module are opposite said contacts of said antenna and the module is encapsulated into the recess,

placing on a face of said antenna support layer featuring the antenna at least one layer of thermo-adhesive film,

placing a cover layer on the layer(s) of thermo-adhesive film,

laminating together the antenna support layer, the layer(s) of thermo-adhesive film and the cover layer.

2. The method of claim 1, wherein a step preliminary to the manufacturing step of the antenna consists in embossing on a thickness between 50 and 60 μ

m a portion of said antenna support layer at the location of the module, the embossing thus created being of a shape slightly larger than the module.

3. The method of claim 1, wherein the layer of thermo-adhesive film directly applied on the antenna support layer is provided with a recess at the location of the module, the shape of the recess is such that it matches the edges of a lower face of the module.

4. The method of claim 1, wherein the adhesive material applied to the antenna support layer is a cyanoacrylate glue.

5. The method of claim 1, wherein the synthetic paper of said antenna support layer is made of a material that does not deform when the temperature increases.

6. The method of claim 1, wherein said layer(s) of thermo-adhesive film have a thickness of 50 μ

m.

7. The method of claim 1, wherein said antenna is made by screen printing using conductive ink.
