<p>PURPOSE: A printed circuit board is provided to suppress noise transmission and unnecessary electromagnetic emission by blocking a transmission path of the unnecessary electromagnetic wave. CONSTITUTION: At least two printed circuit boards(100) are separated with a slot. A connection unit connects two printed circuit boards and is a resistive material(110) with the preset conductivity. The resistive material forms a new path of a parallel resistor in a return current plane of the printed circuit board. The conductivity of the resistive material is 400s/m and is determined based on the signal transmission characteristic and the noise transmission characteristic between two printed circuit boards.</p> |
