  • Patent number: 7276673
    Abstract: A solder bonding method and a solder bonding device are provided, in which solder is melted, and heating of electrode portions is performed by irradiating laser light to an inner side of a region where electrodes portions are provided, making the temperature difference between the electrode portions and the melted solder smaller to improve the wettability of the solder and increase bonding reliability. The solder bonding method and the solder bonding device perform bonding of the electrode portions that are formed on an object to be bonded by melting the solder. After supplying the solder onto the electrode portions before melting, a laser is irradiated to the solder and to the electrode portions in the periphery of the solder. The solder melts, and the electrode portions are heated. The wettability of the solder with respect to the electrode portions thus improves, and the reliability of an electrical connection between the electrode portions can be increased.

    Abstract: A method and a system for stabilizing the sight line of a chip component being carried on two discs, for stabilizing delivery of the chip component between the two discs, and improving and stabilizing the inspection accuracy in the visual check of the chip component. This is achieved by employing a mechanism for carrying the chip component while supporting it on the horizontal plane of the first rotary disc and then carrying the chip component while suction-holding it on the vertical plane of the second rotary disc. When the chip component is carried on the first rotary disc, the upper surface and one side face of the chip component are imaged by first and second cameras. When the chip component is carried on the second rotary disc, the lower surface and the other side face of the chip component are imaged by third and fourth cameras.

    Abstract: Provided is a mounting apparatus which enables high levels of both maintenance/improvement of product quality and reduction of product cost by reliably preventing accidental contact of a mounting part with a mounting target part while enhancing the productivity. In S1, a contact detection start position Hs0 is set. In S2, a chip holding tool chucks an electronic part. In S3, S4, the tool is moved to a transfer position A, and then the tool is lowered to the Hs0 from the transfer position A. In S5, after the tool is lowered to the Hs0, the lowering speed is changed to a contact detection speed. In S6, it is determined whether or not the electronic part has come into contact with a substrate. If the result of the determination is YES, in S7, the lowering of the tool is stopped. In S8, the actual contact position Hc is measured. In S9, the next contact detection start position Hs1 is set, and Hs1 is set to Hs0 (Hs0-Hs1) so that the later steps reflect this setting.
