摘要
The present invention provides a printed circuit board (PCB) board, a core for manufacturing the PCB board and a method for manufacturing the PCB board. The PCB board is in a shape of a rectangle and comprises a fiber layer formed of interlacedly weaved fiberglasses, a metal layer affixed onto a surface of the fiber layer, and a pair of differential signal traces formed on the metal layer, wherein extending directions of the fiberglasses lie at acute angles with respect to a length direction of the rectangle, and the pair of differential signal traces extends along a width direction or the length direction of the rectangle. The PCB board can effectively reduce the possibility of the skew distortion during the transmitting process of the differential signal through adjusting the angle between the fiberglasses and the edge of the core without adjusting or redesigning the original circuit layout.
