# Circuit boards: references

70 records: 0 read sources that the rules and checks may cite, and 70 records catalogued from the Reference Map, not yet read. PCBs by job, with their evidence (ERC, DRC, routing, assembly).

Catalogued records are search snippets: their numbers are the authors' claims and their licences are as the map states them, unread. Cite one only after reading it.

The same records as JSON: https://cad-agent.valpatel.com/catalog/references/circuit-boards.json. All areas: [references](../references.md).

## Coverage

What cad-agent checked when the map was made; each drafted issue was never posted.

- **PCB design rules** (Partly): No fab-capability rules (min trace/space 4-6 mil, annular ring, drill, board edge clearance, via size, mounting-hole keepout), no stackup or impedance data; DRC rules live in the user's KiCad project. Drafted issue, never posted: "Add fab capability profiles for PCB (trace, drill, annular ring)".
