About lead free solder / 無鉛ハンダについて
All of the P.C.B.s installed in this unit and solder joints are
soldered using the lead free solder.
Among some types of lead free solder currently available,
it is recommended to use one of the following types for
the repair work.
•Sn+Ag+Cu(tin+silver+copper)
•Sn+Cu(tin+copper)
•Sn+Zn+Bi(tin+zinc+bismuth)
Caution:
As the melting point temperature of the lead free solder is
about 30°C to 40°C(50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable to
each solder.
本機に搭載されているすべての基板およびハンダ付けに
よる接合部は無鉛ハンダでハンダ付けされています。
無鉛ハンダにはいくつかの種類がありますが、修理時に
は下記のような無鉛ハンダの使用を推奨します。
•Sn+Ag+Cu（錫 + 銀 + 銅）
•Sn+Cu（錫 + 銅）
•Sn+Zn+Bi（錫 + 亜鉛 + ビスマス）
注意：
無鉛ハンダの融点温度は通常の鉛入りハンダに比べ 30 〜
40℃程度高くなっていますので、それぞれのハンダに合っ
たハンダごてをご使用ください。
