standard solderor solderthatcontainslead.
Wewill use PbF solderwhendiscussing theleadfree solderusedinour manufacturing process
whichismadefrom Tin(Sn), Silver(Ag), and Copper(Cu).
Thismodel, and otherslike it, manufacturedusing leadfree solderwill have PbF stampedon the
PCB. For service and repairworkwesuggestusing thesametypeofsolderalthough, withsome
precautions, standard Pbsoldercanalsobeused.
Caution
-PbF solderhas amelting pointthat is50°F~70°F(30°C~40°C)
higherthanPbsolder. Please use asoldering iron with
temperaturecontrol and adjust itto700°F±20°F(370°C±10°C). In

nottoheat too long.
-PbF solderwill tend tosplashifitisheatedmuchhigherthanits
melting point, approximately1100°F(600°C).
-Ifyou must use Pbsolderon aPCB manufacturedusing PbF
solder, removeas muchoftheoriginal PbF solderas possibleand
besurethat anyremaining ismeltedpriortoapplying thePb
solder.
-Whenapplying PbF soldertodoublelayeredboards, please check
