1-8. 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

. 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 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.
