1.2. ABOUTLEADFREE SOLDER(PbF)
Distinction ofPbF PCB: PCBs(manufactured)using leadfree solderwill have aPdF stampon the
PCB.
Caution:
-Pbfree solderhas ahighermelting pointthanstandardsolder,
Typicallythemelting pointis50-70°F(30-40°C)higher.
Please use ahigh temperaturesoldering iron. Incase ofsoldering
iron withtemperaturecontrol, please set itto700±20°F(370±10°C).
-Pbfree solderwill tend tosplashwhenheatedtoo high (about
