How it works

Fresh eyes on your board, before it goes to fab.

01

The review

We check the schematic, the layout and the BOM.

Schematici
Every part against its datasheet.
  • Swapped TX/RX and mirrored pinouts
  • Regulator caps outside the stable range
  • Missing pull-ups on I²C, reset and enable
  • Strap pins that boot the wrong mode
  • Connectors with no ESD or reverse protection
Layouti
What the copper will really do.
  • Footprints that don’t match the part
  • Fast signals crossing a plane split
  • Decoupling too far from its pin
  • Traces too thin for their current
  • Gaps and drills the fab can’t build
BOMi
Parts you can actually buy and build.
  • End-of-life and out-of-stock parts
  • Voltage and power ratings with no margin
  • Values that differ from the schematic
  • Packages that don’t fit the footprint
  • Single-source parts with no alternate
