Precautions for using lead-free solder
1 Employing lead-free solder
"Input, Output, R/C Receiver, Key and Fan 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:
2 Using lead-free wire solder
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 soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldening bit,
contact our service station or service ranch 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 wettabillty, 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 excoeded, remove the bit from the PWB as soon as you conurm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum 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, file it with steel wool or fine sandpaper.
Becareful when replacing parts with polarity indication on the PWB silk.
