Embodiment Construction

[0014] refer to Figures 1 to 6 The integrated circuit card with two connection modes of the present invention is composed of a non-contact connector in the form of an antenna 1 contained in a support plate 2 and an assembly (see FIGS. 4 and 5) given by a general reference number 3, which The assembly comprises a support membrane 4 mated to a conductive area 5 connected to the integrated circuit 6 by wires 7 to provide contact connections and connected to the integrated circuit 6 by wires 19 to provide a contactless contact with the integrated circuit 6. The conductive area 18 of several connectors of the interface. The integrated circuit 6 and the connecting wires 7 and 19 are embedded in a resin block 8 .

[0015] The antenna 1 has two adjacent ends forming a connection circuit for connecting the contactless connection formed by the antenna to the conductive area 18 of the module. For an optocoupler, such a connecting circuit can consist of several conductive tracks extend...

Abstract

An integrated circuit card with two connection modes. The integrated circuit card includes a card body in which there is embedded a link circuit for linking a contactless coupling element (1) to a module having an integrated circuit (6) connected to conductive areas carried by a support film (4). The link circuit extends in register with conductive areas (18) dedicated to making a contactless link and is connected to said conductive areas by an electrically conductive material (32, 36, 42) filling blind holes (31, 35, 41). The blind holes have sections that increase from a bottom of each hole towards an opening thereof over at least a portion of their height.

Description

technical field [0001] The invention relates to an integrated circuit card with two connection modes. Background technique [0002] A card with two connections means a card that can be connected to a device either through a connection that contains contacts, that is, through a metal connection that is flush with the contact area on the outside of the board, or through a contactless connection cards. For a contactless connection, the card includes a contactless coupling such as an induction loop, a radio antenna or an optocoupler via a connection circuit embedded in the card to the Contains an interface connected. [0003] European patent document EP 682,321 discloses an integrated circuit card with two connection methods, which includes an integrated circuit card body embedded with an antenna connected to a component, which includes a support film The integrated circuit is connected to the conductive area contained in the chip, and the antenna has two ends aligned with th...
