ENGINEERING WORKSHEET

6 layer pcb stackup planner

Add the nominal thicknesses of six copper layers and five dielectric intervals. This worksheet does not predict impedance, fabrication tolerance or finished-board acceptance.

Thickness inputs in micrometres (µm)
Layer / interval	Nominal thickness (µm)
L1 copper
Dielectric L1–L2
L2 copper
Dielectric L2–L3
L3 copper
Dielectric L3–L4
L4 copper
Dielectric L4–L5
L5 copper
Dielectric L5–L6
L6 copper

Enter your proposed construction, then calculate.

Use the result as a discussion starting point

The example values are arithmetic inputs, not an approved manufacturing stackup. Solder mask, surface finish, pressing behavior and tolerances are not included. Confirm finished copper assumptions and the actual construction with engineering before release.

For impedance, use the appropriate transmission-line model with confirmed trace geometry, reference planes and material properties. This planner intentionally does not display a guessed impedance.
