1-6. Lead-free Solder

All boards mounted in this unit use lead-free solder. Be sure to use lead-free solder when repairing the
boards of this unit. A lead free mark (LF) indicating that the solder contains no lead is printed on each
board.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular
size.)

. The lead-free 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.
