1-3. 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.)
: LEAD FREE MARK
m
. 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 dC
higher than the ordinary solder, therefore, it is recom-
mended 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.
