1. Warning
Caution:
- Pb free solder has a higher melting point that standard solder Typical the melting point is 50 - 70°F (30 - 40℃)
a higher. Please use soldering iron with temperature control and adjust it to 750 ±20°F (400 ± 10℃).
In case of using high temperature soldering iron, please be careful not to heat too long.
- Pb free solder will tend to splash when heated too high (about 1100°F / 600℃).
