Abstract:
1. A method of mounting a combination-type IC card having: (i) a tuning circuit including an antenna and a tuning capacitor for trimming on a first substrate; (ii) an IC module electrically connected to the tuning circuit and mounted on the first substrate, wherein the IC module including an LSI, and a contact portion connected to an external device, the LSI and the contact portion mounted on a second substrate; and (iii) a resonance circuit including the tuning circuit and the LSI, wherein the method of mounting a combination-type IC card comprising: a milling step of making a hole in the first substrate in which the IC module is mounted; a trimming step of setting a resonance frequency to one of various resonance frequencies by selectively cutting a signal line which connects the tuning capacitor for trimming and the antenna; and an implanting step of mounting the IC module into the hole formed in the first substrate after the trimming step.
