PCB Clearance and Trace Width
Worked for 47 sec
Check result
Gerber export
Table
| Item | Status |
|---|---|
| Preferred trace width 0.15 mm | Present |
| Default trace width | 10 mil = 0.254 mm |
| Keep out | 0.15 mm |
So 0.15 mm is available, but it is not the current default trace width.
DRC check
Table
| Check | Result |
|---|---|
| Floating copper | 2 errors |
| Airwires | No errors |
| Overlapping copper | No errors |
| Missing footprints | No errors |
If you want, I can set the default trace width to 0.15 mm next.

Design Notes
NE555 Motor Driver Board status
Verified fixes
- Q1 is confirmed as IRLZ44NPBF in TO-220AB.
- Q1 schematic connectivity is correct for low-side switching:
- Gate on DRIVE
- Drain on MOTOR_NEG
- Source on GND
- Net naming updated so SPEED_ADJ is now TIMING_C.
- D3 remains the flyback diode placeholder associated with the motor path.
Current blocker
- ERC is clean, but PCB DRC still reports 20 airwires.
- Exported manufacturing files still reflect an older unrouted / legacy transistor state in the PCB copper.
- The available environment does not expose a working routing mutation tool for directly drawing or auto-routing the remaining traces.
Observations from exported files
- IPC-D-356 and Gerber outputs still show old Q1 pad labels (B/C/E) and many N/C entries, indicating the PCB copper/export is not yet synchronized to a fully routed MOSFET layout state.
- Top copper contains only a small amount of routed geometry.
- Bottom copper is largely ground pour plus limited copper features.
Recommended next action
- Complete PCB routing for remaining airwires in the layout editor, then rerun DRC.
- After routing, re-export Gerber and IPC-D-356 and verify that Q1/J2/D3/U1 connectivity matches DRIVE, MOTOR_NEG, VIN_POS, and GND as intended.
