PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"MAIN, SMPS, HDMI PWB" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and
is attached on the PWB a nd service manuals. T h e a lphabetica l cha racter following LF shows the type of
lead-free solder.
Example:
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, if you are not familiar with how to obtain lead-free wire solder or soldering
bit, contact our service sta
Soldering
3.
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lea d
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 of for the maximum heat-resistance
temperat u re of parts may b e exceeded, remove the b it from the PWB as s oon as you confirm the s tea dy
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 sand paper.
Be careful when replacing parts with pola
tion or service branch in your area.
