Soldering Guide
Soldering - Solderen - Soudage - Löten - Soldadura - Lödning - Juottami nen - Saldatura - Solda
Follow these steps for proper soldering:
- Ensure correct component placement and soldering technique.
- Maintain a clean soldering iron tip.
- Apply solder to the joint, not the iron tip.
- Allow solder to cool naturally.
