1-4. Unleaded Solder

Boards requiring use of unleaded 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.)
: LEAD FREE MARK
m
. Be sure to use the unleaded solder for the printed circuit board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 dC 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.
