Impedance Control Calculator
PCB Impedance Calculator
An Impedance Control Calculator helps PCB designers calculate the trace width and spacing needed to achieve a target impedance (e.g., 50Ω) for different PCB stack-ups.
✅ Key Inputs
Your calculator should let the user input:
- Target Impedance (Ω) — e.g., 50Ω
- Dielectric constant (Dk) — e.g., 4.2
- Dielectric height (H) — distance from trace to reference plane (mil/mm)
- Trace thickness (T) — copper thickness (mil/mm)
- Trace configuration — microstrip or stripline
- Optional: Desired trace width (to check the actual impedance)
✅ Key Outputs
It should output:
- Calculated Trace Width (W) — for the given stackup and target impedance.
- Calculated Impedance (Zo) — if the user inputs a trace width instead.
