PRECAUTIONS FOR USING LEAD-FREE SOLDER

='Employing lead-free solder

"PWBs" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and isattached on the PWBs and service manuals. The

alphabetical character following LF shows the type of lead-free solder.

Example:

aa/a

Sn-Ag-Cu

Indicates lead-free solder of tin, silver and copper.

Sn-Ag-Cu

Indicates lead-free solder of tin, silver and copper.

='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 dam-

age or accident due to cracks.

As the melting point of lead-free solder (Sn-Ag-Cu) is higher than thelead wire solder by40 °C, we recommend you to use adedicated soldering

bit, if you are notfamiliar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch inyour area.

='Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by40 °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 confirm 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 adifferent type ofsolder 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 orfine sandpaper.

Be careful when replacing parts with polarity indication onthe PWB silk.
