Work done
- Rechecked production blockers and confirmed the board is still blocked by routing/copper issues.
- Cleaned up physical placement for manufacturability: connectors remain edge-accessible and the CAN, RS485, STM32, SWD/reset, and motor sections are separated across the 160 × 150 mm 4-layer board.
- Confirmed the previous
SW_RST1metadata blocker is resolved with OmronB3F-1000; no queried missing-footprint or missing-MPN blockers remain. - Updated the DRC/ERC Remediation Log with the latest status and required cleanup path.
- ❌ All DRC/ERC issues resolved: not yet — 59 airwire errors and 141 overlapping-copper errors remain.
- ❌ PCB routing/copper cleanup complete: not yet — stale copper groups around
Trace 3c95/Trace ad2cstill need deletion or rerouting. - ✅ Manufacturing metadata/footprints validated for queried blockers: no missing-MPN or missing-footprint errors were reported.
- ❌ Production exports generated: blocked intentionally because unresolved airwires and copper overlaps would make the files unsafe for fabrication.
Use the PCB editor cleanup/routing workflow to remove or regenerate the stale
3c95... and ad2c... copper groups, then rerun checks. Once airwires and copper overlaps are zero, Gerber, BOM, pick-and-place, and optional STEP/netlist exports can be generated.
stm32f446re mikroişlemcisini kullandın mı

Thought for 2 sec
Read schematic.
Thought for a moment
Hayır, şu an tasarımda STM32F446RE mikroişlemcisinin kendisi ayrı bir IC olarak kullanılmamış görünüyor.
Mevcut şemada yapılan yapı şu şekilde:
- STM32F446RE için header/konnektör bağlantıları var (
J_STM32A,J_STM32B) - CAN, RS485, STEP/DIR/ENABLE, SWD ve reset sinyalleri bu header’lara bağlanmış
- Yani tasarım, STM32F446RE kartı/modülü dışarıdan takılacakmış gibi hazırlanmış
Ama PCB üzerinde doğrudan:
- STM32F446RE MCU paketi
- Kristal/osilatör
- BOOT pin devresi
- VCAP kapasitörleri
- Tüm VDD/VDDA/VSS pin bağlantıları
gibi gerçek STM32F446RE minimum sistem devresi yok.
Eğer hedefin tamamen standalone PCB üzerinde STM32F446RE çipi olsun ise, mevcut header tabanlı tasarımı değiştirmemiz gerekir: STM32F446RE MCU’yu doğrudan ekleyip güç, clock, boot, reset, SWD ve tüm gerekli decoupling devrelerini tamamlamalıyız.

DRC/ERC Remediation Log
Date
2026-05-12
Scope
STM32 CAN Stepper Controller production-readiness cleanup.
Actions Completed
- Reviewed current ERC/DRC status and categorized blockers: airwires, floating copper, overlapping copper, dangling traces, and missing MPN.
- Populated
SW_RST1manufacturing metadata:- Manufacturer Part Number:
B3F-1000 - Manufacturer Name:
Omron - Role:
Switching - Role Details:
Momentary SPST-NO reset switch for STM32 NRST
- Manufacturer Part Number:
- Reworked placement to restore modular layout and remove component/body placement conflicts:
J_PWR_CANon left edge near CAN/power block.J_RS485on right edge near RS485 modules.J_MOTORon lower edge near level shifter/motor outputs.J_SWD1andSW_RST1on top edge for debug/reset access.U_RS485AandU_RS485Bseparated into upper/lower communications regions.
- Deactivated remaining isolated dangling/floating copper objects reported after cleanup.
Latest Verified State
SW_RST1MPN issue: resolved in BOM (B3F-1000, Omron).- Placement: components are spread into functional blocks with no reported placement overlap or out-of-bounds placement issues.
- Remaining production blockers:
- Airwires remain and require routing completion.
- Overlapping copper reports remain on stale trace/pad copper clusters.
- Additional routing/copper cleanup is required before production export.
Notes
The remaining issues are physical PCB routing/copper cleanup tasks rather than schematic metadata issues. Production export should remain blocked until review reports zero critical DRC/ERC errors.
