摘要： An apparatus for mounting an electric component onto a board by means of a lead-free solder material. The apparatus of the present invention has a solder material supplying chamber in which a melt of the solder material is supplied to the board by a solder material supplying unit such that the solder material adheres to a predetermined portion of the board. The apparatus further includes a cooling chamber in which the board is cooled by a cooling unit such that the solder material adhering to the board is rapidly cooled to solidify. A conditioning chamber can also be positioned between the solder material supplying chamber and the cooling chamber. The conditioning chamber conditions the board such that the solder material adhering to the board is ensured to be a completely molten condition at least before the rapid cooling of the solder material.

摘要： A barrier metal layer is provided on at least one of two electrodes, with one formed on a substrate and the other connected to an electronic component, so as to coat a base material of the electrode, which base material is made of a material containing Cu. Soldering between the electrode of the electronic component and the electrode on the substrate is conducted by supplying a solder material containing Sn and Bi, contacting the solder material with the barrier metal layer while the solder material is in a molten state; and solidifying the solder material. Thereby, when the electronic component is soldered to the substrate with the solder material such as an Sn—Bi based material or an Sb—Ag based material containing Bi, the degradation of a soldering part is avoided, and thus a sufficient thermal fatigue strength of the soldering part is obtained.

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.
