1-7. Unleaded Solder
Boards requiring use of unleaded solder are printed with a
lead free mark (LF) indicating that 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
d
C
higher than the ordinary solder, therefore, it is recom-
mended to use the soldering iron having a temperature
regulator.
.
An ordinary soldering iron can be used but the iron tip
needs to be applied to the solder joint for a slightly
longer time. The printed pattern (copper foil) may peel
off if the heated tip is applied for too long, so be careful.
