Abstract:
1. A smart card comprising: a card body having a cavity; and a PCB module disposed within the cavity, the PCB module including a PCB and an IC chip flip-chip-bonded to the PCB, the PCB including: a board body having an inner surface to which the IC chip is mounted and an outer surface opposite to the inner surface, an internal circuit pattern on the inner surface, the internal circuit pattern comprising a plurality of internal connection pad groups each constituted by a plurality of internal connection pads and a respective internal connection line connecting the internal connection pads wherein the internal connection pads of each group are located at different relative positions on the inner surface of the board body, an external circuit pattern on the outer surface, the external circuit pattern comprising external contact pads, and connection vias extending through the board body, the connection vias electrically connecting the external contact pads with the internal connection pad groups, and the PCB and the IC chip having corresponding internal and center pads wherein the IC chip has at least one center pad located at a central portion of the IC chip, and one of the internal connection pads of each of at least one of the internal connection pad groups is located at a central portion of the of the PCB and faces and is bonded to the corresponding center pad of the IC chip.
