When the transmission rate increases, the frequency must increase. If the impedance of the line itself changes due to corrosion, stack thickness, and different line widths, signal distortion will occur. Therefore, the conductors on high-speed circuit boards should be controlled within a certain range, which is called "impedance control".

The factors that affect the impedance of the PCB line are the width of the copper wire, the thickness of the copper wire, the dielectric constant of the medium, the thickness of the medium, the thickness of the pad, the path of the ground wire, and the wiring around the line. Therefore, when we design the PCB, we must control the impedance of the routing on the board to avoid electromagnetic interference such as signal reflection and signal integrity as much as possible to ensure the actual use of the PCB board.
