CONTACT SMART CARD |
| 摘要 |
A contact smart card has a smart card contact pad and an IC chip. The smart card contact pad includes a circuit substrate, a card-reader contact element on a first side of the circuit substrate, and a connection element on a second side of the circuit substrate. The card-reader contact element has a noble metal electrically conductive surface, and the connection element has a chip terminal connection surface which is not a noble metal. The IC chip is preferably flip-chip mounted at the second side of the circuit substrate and electrically connected to the chip terminal connection surface. Furthermore, the chip terminal connection surface is preferably an organometallic electrically conductive corrosion protection layer. |
