PRECAUTIONS FOR USING LEAD-FREE SOLDER
1 Employing lead-free solder
“ALL PWB” of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the
PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
2 Using lead-free wire solder
When fi xing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead
wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you to
use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our
service station or service branch in your area.

service station or service branch in your area.
3 Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder by
40°C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended
period of time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be
exceeded, remove the bit from the PWB as soon as you confi rm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and
off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every
use of it.
When the tip of the soldering bit is blackened during use, fi le it with steel wool or fi ne sandpaper.
