摘要

SMART CARD WITH CONTACT, SIM CARD, BANK CARD, IMPEDIMENT OR LIMITATION METHOD OF OXIDATION OF A NON-NOBLE METAL CHIP TERMINAL CONNECTION SURFACE FROM A SMART CARD CONTACT BASE, AND, SMART CARD CONTACT BASE IS a contact smart card 100, 101 having a contact card of the smart card 10 and an ehíjp IC 200, 300 is disclosed. The contact base of the smart card 10 includes a substrate of the circuit 12, a contact element of the card reader 14 on a first side 16 of the substrate of the circuit 12 and a connecting element 18 on a second side 20 of the substrate of the circuit 12. The contact element of the card reader 14 has an electrically conductive metal surface 30 and the contact element connection 18 has a chiji terminal connection surface 36 which is not a noble metal. The IC 200, 300 chip is preferably mounted by flip-chip on the second side 20 of the substrate of circuit 12 and electrically connected to the connection surface of the chiip terminal 36. Furthermore, the connection surface of the chip terminal is preferably a protective layer against conductive organometallic electrical corrosion.
