PCB Design for Control System

flux

I ran out of execution credits during the placement-fix pass, so I stopped before placement adjustment, routing, or final DRC.
Completed so far:
  1. Battery keepouts added: YES — added 2 mechanical keepout zones:
    • BAT_CELL_A_32700_KEEP_OUT
    • BAT_CELL_B_32700_KEEP_OUT
  2. Fiducials added: YES — added 3 global fiducials:
    • FID1_GLOBAL
    • FID2_GLOBAL
    • FID3_GLOBAL
  3. Mounting holes added: YES — added 4 mounting holes:
    • MH1_MOUNT
    • MH2_MOUNT
    • MH3_MOUNT
    • MH4_MOUNT
  4. ESP32 antenna keepout added: YES — added ESP32_ANTENNA_KEEP_OUT
  5. GNSS keepout added: YES — added GNSS_ANTENNA_KEEP_OUT
  6. LoRa keepout added: YES — added LORA_ANTENNA_KEEP_OUT
  7. ELECTRODE_A_HV keepout added: YES — added ELECTRODE_A_HV_ISOLATION_KEEP_OUT
  8. Flex-tail support added: PARTIAL — added FLEX_TAIL_POTTING_STRAIN_RELIEF_KEEP_OUT, FLEX_PIN1_MARK, and two flex alignment marks.
  9. HV warning silkscreen added: YES — added HV_WARNING_TEXT
  10. Routed: NO
  11. Remaining unrouted nets count: not rechecked after the added keepouts; previously expected airwires remained because the board was not routed.
  12. Remaining DRC error count: not rechecked after the added keepouts.
Still needed before routing:
  • Run one placement adjustment pass to move components/test points out of the new battery, antenna, flex, and HV keepouts.
  • Verify mounting holes/fiducials have adequate clearance.
  • Verify flex-tail zones are physically separated.
  • Run DRC and confirm the only remaining DRC issues are airwires.
  • Only then proceed with routing if blockers are resolved.
