The PWB’ s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean
“Lead-Free” solder. The alphabet following the LF mark shows the kind of lead-free solder.
“Lead-Free” solder. The alphabet following the LF mark shows the kind of lead-free solder.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron
tip after com-pletion of soldering work.
tip after com-pletion of soldering work.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
Since the melting point of lead-free solder is about 220˚C, which is about 40˚C higher than that of conventional lead solder, and its
soldering capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This
may cause land separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering
iron from the PWB when completion of soldering is confirmed.

(2) NOTE FOR SOLDERING WORK
(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
Since the melting point of lead-free solder thread is about 40˚C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommendable.

When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a
breakdown or an accident.
