Patent ID: 7630209

Claim:
A universal PCB (printed circuit board) for a smart card, comprising: a board body comprising an inner surface and an outer surface opposite to the inner surface; an internal circuit pattern formed on the inner surface, the internal circuit pattern comprising a plurality of internal connection pad groups each comprising: internal connection pads disposed on the inner surface so as to be electrically connected to chip pads of an IC chip regardless of a change in positions of the chip pads; and an internal connection line connecting the internal connection pads; an external circuit pattern comprising a plurality of external contact pads formed on the outer surface; and connection vias penetrating the board body to connect at least one of the external contact pads and at least one of the internal connection pad groups, wherein at least one of the internal connection pads is located to correspond to the chip pad position on the IC chip when the IC chin is flip-chip-bonded to the internal circuit pattern, and wherein at least one of the chip pads is a center pad located at a center portion of the IC chip, and at least one of the internal connection pads is located at a center portion of the internal circuit pattern so as to correspond to the center pad.
