I review, troubleshoot and optimize existing PCB designs before fabrication or assembly, including schematic issues that can cause unstable operation, failed prototypes or costly board revisions. I can inspect your schematic, PCB layout, BOM and manufacturing files against electrical requirements, component datasheets and your PCB manufacturers design rules.
WHAT I REVIEW & FIX
- Schematic errors, ERC warnings & incorrect connections
- Pinouts, polarity, footprints & component orientation
- Power rails, regulators, decoupling & protection circuits
- Placement, traces, vias, clearances & copper pours
- Grounding, high-current paths & thermal issues
- USB, CAN, UART, SPI, I2C & differential signals
- Connectors, test points & mechanical clearances
PCB OPTIMIZATION
- DRC and manufacturer-specific rule checks
- EMI-aware routing & signal separation
- Trace width, via and current-capacity review
- Solder mask, paste & silkscreen cleanup
- DFM/DFA checks for SMT/THT assembly
- BOM, Gerber, drill & layer-stack verification
DELIVERABLES
- Corrected schematic + PCB source files
- Updated Gerber + NC Drill
- BOM + Pick-and-Place files
- Design issue/fix report
- Optional STEP/3D PCB model
