Problems solved by technology

[0004] At present, since there is no adjustment process for tuning the resonance circuit to a specific frequency in the manufacturing process of the combination card, the characteristic deviation of each batch of LSI and antenna becomes the deviation of the resonance frequency, and the communication characteristics cannot exhibit the predetermined ability
[0005] In addition, there has been a disadvantage of not having a capacitor pattern that can be adjusted in the past

Embodiment Construction

[0037] Hereinafter, an IC card according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0038] This IC card is a combination IC card 1 that performs data communication with a card reader and a card writer as external devices in either contact or non-contact (wireless).

[0039] This combined IC card 1, such as figure 1 , figure 2 As shown, there is a tuning circuit 8 composed of an antenna 3 and tuning capacitors (pattern capacitors) 4, 5, 6, and 7 for adjustment in the antenna card 2, and is electrically connected to the tuning circuit 8 and mounted on the above-mentioned antenna card 2. 9 on the IC module.

[0040] This IC module 9 includes a substrate 10 , an LSI 11 mounted on the substrate 10 by wire bonding, a contact portion 12 mounted on the substrate 10 opposite to the LSI 11 , and connection pads 13 , 14 .

[0041] In addition, a resonant circuit is constituted by the tuning circuit 8 and the LSI 11 describe...

Abstract

The invention is to set a resonance frequency to various resonance frequencies by cutting a signal line which connects a tuning capacitor for trimming and an antenna currently with a milling step making a hole for mounting an IC module.

Description

technical field [0001] The present invention relates to a method for installing a combination IC card (or dual-interface IC card) for data communication with the outside in any mode of contact or non-contact and the combination IC card. Background technique [0002] The combined IC card is an IC card that communicates data with the outside in either contact or non-contact manner. [0003] Since the transmission frequency from the wireless transceiver (R / W) and the resonant circuit in the card must be tuned to receive power when the card is operated in a non-contact manner, the circuit board formed by clamping the front and back of the circuit board with conductors is used. A pattern capacitor (Pattern condenser), a pattern antenna (Pattern antenna), and an LSI (Large Scale Integration) form a resonant circuit. There are also capacitors built into the LSI. [0004] Currently, there is no adjustment process for tuning the resonant circuit to a specific frequency in the manuf...
