1.5 Impedance PCB- Impedance match
If there is signal transmission in the circuit board, it is expected to be smoothly transmitted from the sending end to the receiving end under the condition of minimum energy loss, and the receiving end can completely absorbs it without any reflection. To achieve this kind of transmission, the impedance of the circuit must be equal to the internal impedance of the sending end, which is called "impedance match."
So when the signal is transmitted in the PCB, the characteristic impedance of the PCB board must be matched with the electronic impedance of the head and tail components. Once the impedance value exceeds the tolerance, the transmitted signal energy will be reflected, scattered, attenuated or delayed, resulting in incomplete signal and signal distortion.
 
Impedance match is one of the design elements when designing high-speed PCB circuits. However, the impedance value is absolutely related with wiring mode. For example, whether wiring on the surface layer or inner layer, the distance from the reference power layer or ground layer, the width of wiring, the PCB material, etc. will affect the characteristic impedance of wiring. That is to say, the impedance value can be determined only after wiring layout, while the characteristic impedance produced by different PCB manufacturers is also slightly different. The wiring layout condition of impedance discontinuity cannot be completely considered in general simulation software due to the limitation of the circuit model or the mathematical algorithm used. In this case, only some temninators, such as series resistors, can be reserved on the schematic diagram to mitigate the effect of discontinuous wiring impedance. The method to completely solve the problem is still trying to avoid the occurrence of impedance discontinuities when wiring layout.
