PRECAUTIONS FOR USING LEAD-FREE SOLDER

1. Employing lead-free solder

"MAIN,D|SPLAY,TERM|NAL,SWITCH,USB,POWER,JACK,TUNER.CD MP3,CD MOTOR (PWB ONLY),

CD CHANGER MOTOR (PWB ONLY) PWB" of this model employs lead-free solder.

The LF symbol indicates lead-free solder, and is attached on the PWB and service manuals. The alphabetical character
following LF shows the type of lead-free solder.

IEa

S n-Ag-CU Indicates lead-free solder of tin, silver and copper.

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, ifyou are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station
or service branch in your area.

Example:

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 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.
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.
