- The lead free solder has to be used when repairing the equipment
for which the lead free solder is used.
(Definition: The letter of "PbF" is printed on the PCB 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 PCB 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
degrees C (662±86°F).
Recommended Lead Free Solder (Service Parts Route.)
- The following 3 types of lead free solder are available through the
service parts route.
