Soldering with Iron
- Soldering Iron Temperature : 270±10 ℃
- Apply pre-heating at 120 ℃ for 2~3 min.
- Complete soldering for each terminal within 3 s .
- If the soldering iron temperature exceeds 270±10 ℃ or 3 seconds, it can damage the component.
**Note** : All temperature measurement points are on top surface of the component. If the temperature goes over the recommend, it will cause surface peeling or damage to the component.
