Impedance PCB FAQ
1. Does Solder Mask Affect Impedance?
Solder mask coatings can reduce impedance by up to several ohms.
2. Why do we need controlled impedance?
Controlled impedance is important for solving signal integrity problems, which are distortion-free propagation of signals.
3. How is PCB impedance calculated?
The impedance of a circuit board trace depends on: trace width and thickness. The height of the dielectric layer between the signal trace and the reference plane. The dielectric constant of the dielectric material used in the circuit board.
4. What is an Impedance PCB?
Impedance is the combination of capacitance and inductance when a circuit operates at high frequencies.
