PURPOSE: A printed circuit board(PCB) is provided to minimize the area required for interface by coupling the PCB on the PCMCIA in a vertical direction. CONSTITUTION: A PCB is characterized in that the PCB has stepped edges and connection pads is coupled to face with each other, to thereby minimize a connection area. The PCB includes a ring for fixing the connection area. An outer PCB and an inner PCB have stepped edges formed in an opposite direction, thus significantly reducing the connection area by permitting connection pads to be superimposed with each other in a vertical direction.
