Design Review Checklist

Process

  • Schematic and PCB file names follow standard
  • Export necessary review files (3D model, BOM, etc.)
  • Update relevant system architecture documents
  • Update project README page
  • Simulations uploaded and outputs explained

System

  • Power
    • Sufficient power supplied from upstream source
    • Supply rated for necessary country specifications
    • Estimated total worst-case power supply draw
  • Connectors
    • I/Os are specified
    • Sufficient Current and Voltage rating
    • Mating connectors have matching pinout
    • Same contact material specified for mating connectors
  • Testing
    • Test procedure written
  • Environmental
    • Specified min/max operating temperature
    • Specified min/max storage temperature
    • Specified min/max humidity
  • ROHS compliance requirement review

Components

  • Unpopulated components are denoted DNI
  • Components meet environmental specifications
  • All components have quantity, reference designator and description
  • Suggested and alternate manufacturers listed
  • Price and stock checked for each component
  • Component derating
    • Voltage
    • Current
    • Power at worst-case operating temperature
    • Temperature at worst-case power

Schematics

  • Document
    • Dot on each connection
    • No four-point connections
    • Title block completed for each sheet
    • All components have reference designators and values
    • Multi-part components don't have unplaced symbols
    • Page title present and consistent on all pages if not in title block
    • Symbols identify open collector/drain pins and internal pulled up/down pins
    • Pin names and attributes on symbols with multi-function pins should match actual design usage (I/O/Bi, Name)
    • Components follow preferred reference designator pattern

PCB

  • Manufacturing
    • PCB manufacturing requirements noted on fab layer
      • Plating specified
        • Plating material
        • Plating thickness
      • Layer stack-up specified
      • Minimum trace/space specified
      • Minimum hole size specified
      • PCB color specified
      • Silkscreen color specified
      • Controlled impedance specified
      • Blind or buried vias specified
      • Panelization specified
        • External routing specified (ex. v-groove vs route)
      • Drill table generated
      • All specifications exceed manufacturing tolerance
