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.
