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.

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.
