14、 to use one of the following types for therepair work. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth)Caution:1. As the melting point temperature of the lead free solderis about 30C to 40C (50F to 70F) higher than that ofthe lead solder, be sure to use
15、 a soldering iron suitableto each solder.2. If lead solder must be used, be sure to remove lead freesolder from each terminal section of the parts to bereplaced and from the area around it completely beforesoldering, or make sure that the lead free solder andlead solder melt together fully.The P.C.B
