About this Gig

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
