摘要： A differential signal line wiring method and PCB board, the wiring method comprising: providing a rectangular glass fabric formed by woven and interlaced glass fabrics and an adhesive filled between the glass fabrics (101); determining a wiring direction of a differential line, and acquiring the bundle number of the glass fabric in the direction, the wiring direction comprising a length direction or a width direction of the glass fabric (102); equally dividing the glass fabric in the wiring direction into glass fabric units of equal quantities and bundle number, and acquiring the width of the glass fabric unit according to the dimension and quantity in a direction of the glass fabric perpendicular to the wiring direction, the glass fabric unit comprising the glass fabrics and the adhesive in the wiring direction (103); determining a line spacing and a line width of the differential signal line according to the width of the glass fabric unit (104); and conducting wiring on a metal layer in the wiring direction according to the line spacing and the line width to form a required differential signal line, the metal layer being adhered to a surface of the glass fabric (105). The method solves the problems of high cost, large occupied space of the wiring and a long period of time for the wiring of an existing control differential signal delay line method.
