1.2. ABOUTLEADFREE SOLDER(PbF)
Distinction ofPbF PCB:
PCBs(manufactured)using leadfree solderwill have aPbF stampon thePCB.
Caution:
-Pbfree solderhas ahighermelting pointthanstandardsolder,
Typicallythemelting pointis50-70°F(30-40°C)higher. Please use

ahigh temperaturesoldering iron. Incase ofsoldering iron with
temperaturecontrol,please set itto700±20°F(370±10°C)
-Pbfree solderwill tend tosplashwhenheatedtoo high (about
1100°F/600°C).
Whensoldering or unsoldering, please completelyremove all ofthesolderon thepinsor solder
area, and besuretoheatthesoldering pointswiththePbfree solderuntil itmeltsenough.
