PCB Stackup Calculator

Design multi-layer PCB stackups. Calculate impedance targets per layer thickness.

Number of Layers

Total Thickness (mm)

Core Thickness (mm)

Prepreg Thickness (mm)

Copper Thickness (oz)

Target Z₀ (Ω)

h_diel = (t_total – 2N×t_cu) / (N-1)

For N-layer symmetric stackup. Adjust prepreg and core for impedance.
