A printed circuit board is constructed from various woven fiberglass fabrics, strengthened and bound together with epoxy resin, and includes a signal layer. The signal layer includes a positive differential signal line and a negative differential signal line laid out in parallel following a zig-zag pattern. A first distance and a second distance is designed at a ratio of 1:7. The first distance is a perpendicular distance between a highest point of the negative differential signal line and a reference line formed by connecting all lowest points of the negative differential signal line. The second distance is a perpendicular distance between a lowest point and an adjacent highest point of the negative differential signal line along the direction of the reference line. |
