<p>PURPOSE:To electrically connect top and rear metallic Panels in an easy and assured' manner as an action for preventing an electrostatic noise of an IC card. CONSTITUTION:A pair of spring chips 7a, 7b provided with surface mount electrodes 8 on one-end parts thereof are connected by soldering to the both surfaces of a circuit board 6 incorporated in an IC card. In this manner, top and rear panels can be assuredly brought into electric and mechanic contact with each other and fixed. Therefore, in comparison with a conventional card of a single spring system, a handleability and an assembleability are improved, and an assured assembly can be expected.</p> |
