PCB Design Rules - rules/index.json

by adom

Canonical PCB fab design rules (DRC) for every popular vendor: one JSON record per vendor, process and layer count, with generated Fusion/EAGLE .dru and .edru, KiCad .kicad_dru plus board-setup JSON, Altium .RUL exports, and a human comparison table. Every number cites the vendor's own capabilities page and the date it was read.
