Design rule files

Download the limits above as a rule file for your EDA tool. We generate them from this table, so when the table changes the files change too.

KiCad 8–10 · pcbexpress.kicad_dru: put it next to your project as <project>.kicad_dru. We verified it with KiCad 10 DRC.
Altium Designer · pcbexpress.RUL: Design Rules → Import Rules. In Altium's own export format. We haven't verified the import ourselves yet, tell us if it fails.

We calculate impedance on these stack-ups and confirm with the fab's own after the order. Other thicknesses change the core/prepreg split.
