| Abstract: | A method of the equitable wiring is proposed for solving the problems of signal integrity insufficiency caused by the high-frequency environment in PCB of embedded systems.Several methods to use the wiring techniques to improve signal integrity in the PCB design are summed up by the analysis of the diversified phenomena about signal integrity,and accounting for electrical characteristics of transmission lines,through-holes and corners by modeling.The methods have the actual reference value in the PCB design. |
