Factors affecting wiring impedance 


Usually, the impedance is controlled between 25 and 125 ohms, depending on its composition. PCB designers need to create high-frequency signals to meet the requirements of controlling impedance routing, and it also depends on the circuit board stack containing the material and its dielectric thickness. Therefore, the following are some components required to define control impedance:
 

Circuit board thickness and line width
 

The materials and values of core materials and prepreg
 

Define the dielectric constant of the core material and prepreg of the material
 

Reference grounding layer (basically, this means that controlling impedance routing requires some reference grounding layer)
 

Do you need solder resist.
