1-7. Lead-free Solder
Boards requiring use of lead-free solder are printed with a lead free mark (LF) indicating the solder
contains no lead.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular
size.)

.
Be sure to use the lead-free solder for the printed circuit board printed with the lead free mark.
.
The lead-free solder melts at a temperature about 40
d
C higher than the ordinary solder, therefore, it is
recommended to use the soldering iron having a temperature regulator.
.
The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly
longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so
be careful.
