1. Employing lead-free solder
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder
3. Soldering
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

Lead-free wire solder for servicing
Ref No.
Description
Parts No.
When fixing 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 soldring 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.

recommend you to use a dedicated soldring 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.
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 wet ability, 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 confirm the steady
soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. 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.
