A low noise multilayer printed circuit board includes at least one ground layer and at least one power layer. The at least one ground layer is divided into a first area and a second area. The first area and the second area are connected by a first metal neckline. The at least one power layer is divided into a third area and a fourth area. The third area and the fourth area are connected by a second metal neckline. The first area corresponds to the third area. The second area corresponds to the fourth area. The location where the first and second areas are connected by the first metal neckline is different from that where the third and fourth areas are connected by the second metal neckline.
