摘要： There are provided a method of soldering a lead-free solder which lowers a melting point of the lead-free solder and prevents deterioration of a joining strength at a portion joined by the lead-free solder, and a joined object soldered with the use of the soldering method. The lead-free solder as an alloy of tin with no lead contained is melted, and ultrasonic vibration is acted at least either to the join object to be joined by the lead-free solder or to the lead-free solder when the molten lead-free solder is solidified. Therefore crystals of contained components in the lead-free solder are made fine and the contained components are prevented from being segregated at a joining interface of the joined object, so that the joining strength at the joining interface can be increased.

摘要： A lead-free solder alloy of electrode for joining electronic parts fine in texture and excellent in thermal fatigue resistant characteristic is presented. This is a solder alloy of electrode for joining electronic parts comprising Sn, Ag and Cu as principal components, and more particularly a solder alloy of electrode for joining electronic parts containing 92 to 97 wt. % of Sn, 3.0 to 6.0 wt. % of Ag, and 0.1 to 2.0 wt. % of Cu. By adding a small amount of Ag to the solder mainly composed of Sn, a fine alloy texture is formed, and texture changes are decreased, so that an alloy excellent in thermal fatigue resistance is obtained. Further, by adding a small amount of Cu, an intermetallic compound is formed, and the junction strength is improved.
