  • Non-contact ID card and manufacturing method thereof
    Patent number: 7332798
    Abstract: Provided is a non-contact ID card which is superior in the productivity and the electrical properties, and a method capable of manufacturing such non-contact ID card. The non-contact ID card of the present invention is characterized in that the non-contact ID card comprises an antenna circuit board in which an antenna is formed on a substrate and an interposer board in which an enlarged electrode, which is connected to an electrode of an IC chip, is formed on a substrate on which the IC chip is mounted. The non-contact ID card is formed by laminating both boards in such a manner that the electrode of the antenna and the enlarged electrode are bonded, in which both electrodes are adhesively bonded by an insulating adhesive filled in minute recesses dispersed on bonding faces of the electrode of the antenna and/or the enlarged electrode.

  • Non-contact ID card and the like and method for manufacturing same
    Patent number: 7275696
    Abstract: A low-cost non-contact ID card having practical electrical properties and the like is disclosed. The non-contact ID card comprises an antenna circuit board wherein an antenna is formed on a substrate and an interposer board wherein an enlarged electrode is formed on a substrate that is mounted with an IC chip. The enlarged electrode is connected to an electrode of the IC chip. The antenna circuit board and the interposer board are joined in such a manner that an electrode of the antenna is in direct contact with the enlarged electrode which is a resin electrode made of a conductive resin containing a thermoplastic resin.

  • Noncontact ID card and method of manufacturing the same
    Publication number: 20050110129
    Abstract: A noncontact ID card composed by laminating an antenna circuit board where an antenna is formed and an interposer board formed by connecting an enlarged electrode to an electrode of a mounted IC chip and bonding between an antenna electrode of the antenna circuit board and the enlarged electrode of the interposer board with electroconductive adhesive material, wherein a substrate of the antenna circuit board and a substrate of the interposer board are bonded. In addition, in another composition, at least one local deformation is applied to a boding face of the electrodes each other in a direction crossing the bonding face.
