Abstract

An RFID tag mounting circuit board has a configuration in which an RFIC chip, a minimum antenna, a circuit which matches the impedance of the RFIC chip and that of the antenna are mounted on a printed circuit board. With this configuration, the area occupied by the antenna of an RFID tag is suppressed, and decrease in the component mounting density of the printed circuit board is suppressed. The RFID tag mounting circuit board is configured to be capable of managing the histories of all components on a per-printed-circuit-board basis by attaching a reading device for an RFIC chip to a chip mounter which mounts an IC chip.
