1. ABOUTLEADFREE SOLDER (PbF:Pbfree)
Note:
Intheinformation below, Pb, thesymbol for leadintheperiodictableofelements,
will refertostandard solderor solderthat containslead.
Wewill use PbF solderwhendiscussing theleadfree solderusedinour
manufacturing process whichismadefromTin(Sn), Silver(Ag), and Copper(Cu).

Thismodel, and otherslike it, manufacturedusing leadfree solderwill have PbF
stampedon thePCB. For service and repairworkwesuggest using thesametype
ofsolderalthough, withsomeprecautions, standard Pbsoldercanalsobeused.
Caution
- PbF solderhas amelting pointthat is50°F~70°F(30°C~ 40°C) higherthanPb
solder. Please use asoldering iron withtemperaturecontrol and adjust itto
700°F±20°F(370°C±10°C). Incase ofusing high temperaturesoldering iron,
please becareful nottoheat too long.
- PbF solderwill tend tosplashifitisheatedmuchhigherthanits melting point,
approximately1100°F(600°C).
- Ifyou must use Pbsolderon aPCB manufacturedusing PbF solder, remove as
muchoftheoriginal PbF solderas possibleand besurethat anyremaining is
meltedprior toapplying thePbsolder.
- Whenapplying PbF soldertodoublelayeredboards, please check the
componentsidefor excess whichmay flowontotheopposite side(See thefigure
below).
