7 Steps to Your First PCB
- ▸1. Finalize schematic — all components, decoupling caps, test points
- ▸2. Choose tool — KiCad (free, professional) or EasyEDA (beginner friendly)
- ▸3. Set design rules — min 0.1mm trace, 0.2mm drill for budget fabs
- ▸4. Place components — decoupling caps adjacent to IC power pins
- ▸5. Route traces — power first, then signals
- ▸6. Run DRC — zero errors before sending
- ▸7. Export Gerbers and order from JLCPCB or PCBWay (~$5 for 5 boards)
Common First-Timer Mistakes
- ▸No decoupling capacitors on IC power pins
- ▸Wrong component footprint — always verify with real part
- ▸Thin power traces — use 1mm per amp minimum
- ▸No ground plane — use copper pour
- ▸No test points — makes debugging impossible
💡 Tip: Have someone else review your design before sending to fab. Fresh eyes catch what you've stopped seeing.
