PCB DFM Checklist

PCB DFM checklist for design for manufacturing review

DFM review catches avoidable fabrication and assembly issues before a PCB order is placed. This checklist is useful for KiCad, Altium, EasyEDA, and Eagle projects.

Fabrication DFM checks

• Trace width, spacing, via size, and annular ring match the manufacturer capability.
• Copper-to-edge clearance is suitable for the fabrication process.
• Solder mask slivers, paste openings, and exposed copper areas are intentional.
• Silkscreen does not overlap pads, test points, or small component bodies.

Assembly DFM checks

• Component spacing allows reliable pick-and-place and rework.
• Polarity and pin 1 indicators are visible after assembly.
• Large connectors, tall parts, and heat-generating components have enough clearance.
• Do-not-populate parts and hand-soldered parts are clearly documented.

Production-readiness checks

• BOM parts are available, correctly packaged, and not end-of-life.
• Programming, calibration, and test points are reachable.
• Thermal, power, and current paths are reviewed for the expected load.
• Board revision, file names, and vendor instructions are consistent.
