17、X459 HTR-5935 無鉛種類、修理時下記 無鉛使用推奨。 Sn+Ag+Cu （錫+銀+銅） Sn+Cu （錫+銅） Sn+Zn+Bi （錫+亜鉛+） 注意： 1. 無鉛融点温度通常鉛入比3040 程度高、合 使用。 2. 鉛入使得場合、交換 部品端子部周辺部無鉛取除、 無鉛鉛入十分溶状態 付。 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

18、 + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: 1. 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. 2. If lead solder must be

19、 used, be sure to remove lead free solder from each terminal section of the parts to be replaced and from the area around it completely before soldering, or make sure that the lead free solder and lead solder melt together fully.
