    摘要: In a jet soldering method, a substrate is held by an actuator and pre-heated by a pre-heater. The pre-heater has a shield member or the substrate is swung to equalize temperature distribution in the substrate. The substrate is then transferred over a primary jet soldering bath while dipping a treatment surface of the substrate in a primary solder jet, so that solder stick to the treatment surface of the substrate. Then, the substrate is transferred over a secondary jet soldering bath while dipping the treatment surface in a secondary solder jet, so that the solder sticking to the substrate is shaped. The transfer conditions of the substrate are differentiated between transfers over the primary jet soldering bath and the secondary jet soldering bath.

    摘要: In a method of soldering a work-piece in a state where the work-piece contacts a wave molten solder, a soldering process is performed while controlling an immersion depth of the work-piece into the wave molten solder to be constant. The immersion depth control is performed by changing one of a height position of the work-piece and a wave height of the wave molten solder based on a displacement amount of the work-piece in a height direction thereof. Accordingly, the soldering process can be performed with high quality even when the work-piece is thermally warped.

    摘要: In a flow soldering apparatus, a substrate is clamped by a pair of nails of a chuck mechanism and transferred over a molten solder barrel while being held in contact with a molten solder. The nails are held resiliently to each other, so that the substrate is allowed to expand thermally between the nails without bowing. The chuck mechanism has a scraper nail which extends transversely over the entire lateral length of the substrate at the front side of the substrate in a substrate transfer direction to push away an oxide film formed on the molten solder. The chuck mechanism is constructed to allow the molten solder to enter underneath the substrate in the lateral direction with respect to the substrate transfer direction. After completing one soldering operation, the nails change the set of the opposing two sides to another set of two opposing sides of the substrate, so that the substrate is subjected to the soldering operation from a direction different from the preceding soldering operation.

    摘要: When a sealed rolling bearing is subjected to temperature increase caused by the friction heat of the seal and external heat and is subsequently cooled down, negative pressure is created in an internal space of the bearing and causes a seal lip of the bearing to stick to a seal groove, resulting in abrasion of the seal lip. The present invention solves the problem while maintaining sealing performance of the seal lip. In a sealed rolling bearing in which a sealing member has a seal lip on its edge and the seal lip abuts against a raceway-side groove wall of a seal groove adjacent to an inner raceway, the seal lip has a contact tip shaped into an arc whose radius of curvature R ranges from 0.1 mm to less than 0.2 mm.
