Attachment Access Issue


The earlier “PCB Placement Setup” report was a no-op due to unavailable capacity; I’ve now rerun that scope successfully. I’m reconciling the new live placement and DRC, then proceeding directly to routing.
Placement is confirmed valid: 100 × 100 mm, 2 layers, four symmetric M3 holes, all 17 components top-side, and no placement/stackup violations. The board passes routing preflight; I’m routing the 25 remaining connections now.
The PCB setup and placement are now complete and verified:
  • 100 × 100 mm rectangular, standard 2-layer board
  • Four symmetric 3.2 mm M3 mounting holes at ±44 mm
  • All 17 components placed top-side and within bounds
  • Zero overlap, keepout, edge-placement, missing-footprint, or stackup violations
  • Routing preflight initially passed with 25 airwires remaining
Auto-routing was started but paused before completion. It returned a generic placement anomaly that still needs inspection, despite the preceding placement checks being clean.
Remaining work
  • Inspect and resolve the router’s generic placement anomaly.
  • Resume routing all 25 connections.
  • Add and verify GND copper and stitching vias.
  • Run final ERC, DRC, and airwire checks.
  • Export Gerbers, NC drills, BOM, and pick-and-place data.
Execution stopped because your ACUs ran out.
