7 Steps to Your First PCB
- โธ1. Finalize schematic โ all components, decoupling caps, test points
- โธ2. Choose tool โ KiCad (free, professional) or EasyEDA (beginner friendly)
- โธ3. Set design rules โ min 0.1mm trace, 0.2mm drill for budget fabs
- โธ4. Place components โ decoupling caps adjacent to IC power pins
- โธ5. Route traces โ power first, then signals
- โธ6. Run DRC โ zero errors before sending
- โธ7. Export Gerbers and order from JLCPCB or PCBWay (~$5 for 5 boards)
Common First-Timer Mistakes
- โธNo decoupling capacitors on IC power pins
- โธWrong component footprint โ always verify with real part
- โธThin power traces โ use 1mm per amp minimum
- โธNo ground plane โ use copper pour
- โธNo test points โ makes debugging impossible
๐ก Tip: Have someone else review your design before sending to fab. Fresh eyes catch what you've stopped seeing.
