Abstract: A printed circuit board layout method includes the following steps. A printed circuit board with a signal layer and a pair of differential transmission lines positioned on the signal layer is provided. A first distance is determined; when the distance between the pair of differential transmission lines is greater than the first distance, an eye width and an eye height of an eye diagram nearly remains the same. When a distance between the pair of differential transmission lines is less than the first distance, an eye width and an eye height of an eye diagram decreases. A second distance that is less than the first distance is set between the pair of differential transmission lines which makes the eye width and the eye height greater than a predetermined value, and which is determined by a Far End Crosstalk (FEXT) on the eye diagram when the pair differential transmission lines transmit signals.
