    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.

    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 for joining electronic parts comprising Sn, Ag, Bi, Cu and In as principal components, and more particularly a solder alloy of electrode for joining electronic parts containing 81 to 91 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.

    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 docking and active damping device for space structures is provided, in a docking portion of one space structure to be docked, with a positioning device in which an output rotor can be moved and rotated within a two-dimensional plane by a composite rotation of one or more eccentric rotors capable of being independently driven and controlled by a direct drive motor and the output rotor, and a docking member having a docking ring and a latch mechanism are supported on the output rotor of the positioning device. A probe having a capture device capable of being protruded and driven in an axial direction by a linear motion is provided inwardly of the docking member, and the probe provides a 4-freedom movement according to a position of the passive side to capture and dock a drogue. The docking ring is supported through a strain sensor, a vibration of the passive side structure is detected, and the docking member is moved in a direction of suppressing the vibration to promptly suppress the vibration caused by disturbances from the inside and outside of the space structures.
