What is DFM? Design for Manufacturing in PCB Explained
2026-09-27 06:00:00 | pcba-mkr
DFM (Design for Manufacturing) designs PCBs that can be reliably manufactured.
Common DFM Checks:
- Trace width and spacing meet fab minimums
- Hole size matches drill capabilities
- Solder mask and silkscreen clearance
- Annular ring around vias and pads
- No acute angle traces
- Thermal relief on large copper pads
Why DFM Matters:
- Prevents costly PCB respins
- Reduces assembly defects
- Improves yield and reliability
Most PCB fabs offer free DFM review. Always upload Gerber files for DFM check before ordering.
