DC Board DRC Fixes
Worked for 2 mins 24 sec
Dangling trace cleanup is complete.
- Found 31 dangling-trace warnings.
- Deleted 60 trace stub nodes tied to those warnings.
- Re-ran dangling-trace DRC at 2026-05-15 22:12:22 UTC.
- Remaining dangling traces: 0
No schematic edits or connector moves were made.
Check the layout for unrouted nets after removing those stubs.
Thought for 13 sec
I’ll check the layout for unrouted nets by running the airwire DRC now, then I’ll report the current unrouted count and affected items without making routing changes.
Worked for 32 sec
Layout check found 33 unrouted airwire errors after the overlap and dangling-stub cleanup.
Current cleanup status:
- Overlapping copper: cleared to 0
- Dangling traces: cleared to 0
- Unrouted nets / airwires: 33 errors remain
Next step is routing those remaining airwires, preferably in phases: power/ground first, then signals.

Implementation Status — Industrial Welding IoT Controller
Updated: 2026-05-08
Latest ERC/DRC remediation pass
A fresh ERC/DRC review was fetched from the current project state after targeted placement cleanup. The remaining active findings are layout-related only:
- Airwires: 5 active errors.
- Dangling traces: 6 active warnings.
- Floating copper: 3 active errors.
- Overlapping copper: 131 active errors.
- Missing footprints / invalid layers / selected schematic ERC categories: no active error or warning findings were returned in the filtered review set.
Targeted actions completed
- Re-ran the current ERC/DRC review from the latest project state.
- Preserved the existing controller architecture and avoided schematic redesign.
- Ran a targeted component placement remediation pass rather than full board redesign.
- Adjusted J3, J6, J14, C8, C9, and R2 to improve board-edge spacing and keep components inside the intended mechanical envelope.
- Confirmed the board remains a 160 mm × 100 mm, 6-layer layout with the original industrial controller zoning intent preserved.
Current blocker
The remaining active findings are stale/conflicting routed copper, floating copper islands, dangling trace segments, and unrouted airwires. Correctly clearing those requires PCB trace cleanup/deletion and re-routing of affected nets. The current execution environment does not expose the necessary trace-removal or routing controls, so these remaining layout errors cannot be fully cleared here without manual PCB routing cleanup or access to routing/removal operations.
Manufacturing readiness
Status: Not manufacturing-ready yet. The schematic architecture and PCB placement intent are preserved, and component-level/schematic review categories checked clean, but fabrication export should wait until the remaining copper overlaps, floating copper, dangling traces, and airwires are cleared and DRC is re-run clean.
Recommended next manual/EDA actions
- Delete or clean the stale dangling/floating trace segments identified by the latest review.
- Re-route the remaining airwires using the existing 6-layer stackup.
- Re-run DRC for overlapping copper, floating copper, dangling traces, and airwires.
- Proceed to Gerber/BOM/pick-and-place export only after those checks are clean.
