Top 5 impact factor on the impedance control
Top 5 impact factor on the impedance control
In the normal PCB design conditions, the following factors mainly caused by the PCB manufacturing impact on the impedance:
1, the dielectric layer thickness and impedance value is proportional to.
2, the dielectric constant and inversely proportional to the impedance value.
3, copper foil thickness and resistance value is inversely proportional.
4, line width and impedance value is inversely proportional.
5, the ink thickness and resistance value is inversely proportional.
So we should pay attention to the above points in the control of impedance.
