I review, fix, and optimize existing PCB designs before fabrication and assembly, helping identify issues that can cause failed prototypes, unstable operation, assembly problems, or costly board revisions. I can evaluate your schematic, layout, BOM, and production files against electrical requirements and your PCB manufacturers capabilities.
WHAT I REVIEW & FIX
- Schematic ERC and PCB DRC issues
- Footprints, pinouts, polarity & component placement
- Trace widths, spacing, vias & copper pours
- Ground planes, decoupling & power distribution
- High-current paths, thermal design & sensitive signals
- USB, CAN, SPI, I2C, UART & differential pairs
- Connectors, mounting holes & enclosure clearances
DFM/DFA OPTIMIZATION
- Manufacturer-specific fabrication rules
- Solder mask, paste, silkscreen & courtyard checks
- SMT/THT assembly accessibility and test points
- BOM review, alternatives & component availability
- Gerber, drill and layer-stack verification
DELIVERABLES
- Corrected schematic & PCB source files
- Updated Gerber + NC Drill files
- BOM + Pick-and-Place/Centroid files
- Review report highlighting identified issues and fixes
- Optional STEP/3D board model
