  • Patent number: 8035522
    Abstract: A circuit chip having a loop-shaped antenna coil on a main surface and a tag sheet having an antenna pattern on a main surface are prepared, and the circuit chip is mounted on the main surface of the tag sheet so as not to place over the antenna pattern. The circuit chip is placed closely to the antenna pattern, and at least the half of the main surface is desirably faced against the antenna pattern. Thus, signals and/or power can be securely exchanged between the circuit chip (or antenna coil) and the antenna pattern. Therefore, a high-performance and rigid RFID tag can be obtained by roughly aligning the circuit chip and the tag sheet.

  • Patent number: 8009047
    Abstract: For protecting information stored in an RFID chip and ensuring its authenticity, radio communication between the RFID chip and an external terminal is positively interrupted when a seal type RFID tag including the RFID chip is peeled from an adherend, while ensuring solidity integrity when the RFID tag is put on the adherend. In the seal type RFID tag which includes the RFID chip fixed on a mounting surface of a base member having an adhesive layer applied thereto and which is put on the adherend by using the adhesive layer, an antenna formed on a main surface of the RFID chip is embedded in adhesive layers together with the RFID chip and an adhesive bonding strength between the antenna and the adhesive layer is made greater than a joining strength between the antenna and the RFID chip.

  • Patent number: 7615870
    Abstract: Cut pieces of a flexible tape respectively having positioning holes are superposed on a substrate having positioning holes, while positioning the substrate and the cut pieces by inserting a positioning pin into the positioning holes respectively, so that one side of the substrate faces one side of the cut pieces. Subsequently, internal terminals provided on the substrate are ultrasonically joined with internal terminals provided on the cut pieces by pressing an ultrasonic tool from the other side of the cut pieces. As a result, connection between these can be performed highly accurately. Further, since the internal terminals are ultrasonically joined with each other, operation time does not increase in proportion to the number of terminals, as in the connection using a bonding wire, and misregistration due to heat does not occur. Accordingly, connections between circuit boards are performed efficiently, highly accurately, and reliably.

  • Publication number: 20070007344
    Abstract: In an RFID (radio frequency identification) tag comprising an antenna formed of a conductive paste containing conductive filler like silver flakes on a base member, and an RFID chip connected to the antenna, the present invention cures a pattern of the antenna formed of the conductive paste, and then connects the RFID chip to the antenna with thermoplastic resin contained in the conductive paste by heating bump electrodes of the RFID chip in contact with the antenna. According to the present invention, Since the bump electrodes of the RFID chip and the antenna are connected to each other and establish sufficient electrical conduction therebetween without providing an anisotropic conductive sheet or the like therebetween, a highly reliable RFID tag is supplied at a low cost.

  • Patent number: 7122087
    Abstract: There is a method of manufacturing an RFID, in which a semiconductor chip with a memory is bonded to an antenna, so that the information recorded in the memory can be transmitted through the antenna. In the RFID, a PET film, a PEN film, or a sheet of paper is used as the base material of the antenna. The method includes: aligning the semiconductor chip with gold bumps relative to the antenna, in which a metal foil formed of an aluminum or an aluminum alloy is adhered to the base material, including a polyethylene terephthalate or a polyethylene naphthalate; pressing the semiconductor chip to the antenna; and applying ultrasonic waves under an ambient temperature lower than the glass transition temperature of the polyethylene terephthalate or the polyethylene naphthalate, to thereby bond the gold bumps and the metal foil. Thus, the method suppresses the deformation of the antenna.
