@noeliascotti @blind_via Here you go. Follows Wan-Hoorfar 2000 improvement on Svacina 1992's base paper.




Impedance calculation will vary slightly depending on what calculator you are using to determine your trace thicknesses. Famously, PCB designers can get Saturn PCB ToolKit that has an impedance calculator. However, the Fabricators mostly use paid software called Polar. And the results you get between the 2 vary enough to cause issues with the fabricator accepting your impedance calculations. This is why it's a good reason to check with your intended fabrication house before committing to trace thicknesses in your complex design for controlled impedance. KiCAD has its own calculator, but it does not cover asymmetric stack up calculations at all, so I can't use it for those kinds of impedances calculations.

wait I had no clue nextpcb can be cheaper than jlcpcb for prototypes. That's insane

oh come on man
