Abstract:
A printed circuit board includes a body part formed with connection pads on a first surface thereof; and a warpage compensating part formed over the first surface of the body part and having a height that increases from edges toward a center of the warpage compensating part so that an upper surface of the warpage compensating part facing away from the first surface of the body part is convex upward. The warpage compensating part comprises conductive layer patterns formed over the first surface of the body part to be electrically connected to the connection pads; and a solder resist formed over the first surface of the body part so as to expose the conductive layer patterns. The height of the solder resist gradually increases from both edges toward a center of the solder resist.
