Selective Soldering vs Wave Soldering
Wave suits dense, uniform through-hole; selective wins when heat-sensitive parts and mixed SMT/THT share a board.
When to wave
High THT density and tolerant parts favor a single wave pass.
When to selective
Localized jets protect adjacent SMT and sensitive components.
Cost trade-off
Selective adds fixture cost but saves rework on mixed boards.
Key Takeaways
Key Takeaways
- Wave for uniform, dense THT.
- Selective protects nearby SMT.
- Pick by layout, not by habit.
