3.5 General Description About Lead Free Solder (PbF)

The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this equipment in
considering the globally environmental conservation.
The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin (Sn), silver (Ag)
and copper (Cu), and the melting point of the lead free solder is higher approx.30°C (86°F) more than that of the normal solder.

Service caution for repair work using Lead Free Solder (PbF)
The lead free solder has to be used when repairing the equipment for which the lead free solder is used.
(Defnition: The letter of "PbF" is printed on the P.C.B. using the lead free solder.)
To put lead free solder, it should be well molten and mixed with the original lead free solder.
Remove the remaining lead free solder on the P.C.B. cleanly for soldering of the new IC.
Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the lead free
solder.
Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30°C (662±86°F).
