7、both polarities. About lead free solder / 無鉛 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 + sil

8、ver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder. 本機搭載基板付 接合部無鉛付。 無鉛種類、修理時 下記無鉛使用推奨。
