  • Patent number: 8074867
    Abstract: A conductive ball mounting apparatus for mounting conductive balls by providing an array mask having through holes, into which conductive balls are to enter, above a mounting target placed on a stage, by arranging a ball reservoir having an opening for reserving a plurality of conductive balls, in the bottom, by moving the ball reservoir along the array mask, by dropping the conductive balls into the individual through holes of the array mask, adopts the following means. Firstly, the conductive ball mounting apparatus comprises moving means for moving the array mask and the stage relative to each other in horizontal directions. Secondly, the positions of the conductive balls in the through holes are arranged by finely moving at least one of the array mask and the stage relative to each other in the horizontal directions after the balls were dropped.

  • Patent number: 8042722
    Abstract: A conductive ball arraying apparatus includes an arraying jig having ball insertion parts at a predetermined array pattern, a ball cup that has an opening part on a lower surface thereof and is capable of housing a plurality of conductive balls, moving means that moves the arraying jig and the ball cup relatively and moves the ball cup relatively along an upper surface of the arraying jig and dropping off the conductive balls into the ball insertion parts of the arraying jig. The apparatus includes means for detecting a quantity of the conductive balls in the ball cup and detects as to whether the quantity of the conductive balls in the ball cup reaches at least one of an upper limit and a lower limit and/or means for detecting leakage of the conductive balls from a clearance between the ball cup and the arraying jig.

  • Publication number: 20090057372
    Abstract: A conductive ball mounting apparatus includes a stage including a placement surface, stage moving means that moves the stage between a supply position and a mounting position, mounting means that comprises an array mask and mounts the conductive ball to the object to be mounted via the array mask, elevating means that changes a distance between the array mask of the mounting means and the placement surface of the stage, and thickness measuring means provided at the supply position so as to measure a thickness of the object to be mounted placed on the placement surface. The thickness of the object to be mounted is measured at the supply position, and the conductive ball is mounted by controlling the elevating means to set a distance between an upper surface of the array mask and an upper surface of the object to be mounted at the mounting position to a predetermined value in accordance with the measured thickness.

  • Publication number: 20070123068
    Abstract: A conductive ball arraying apparatus adopts the following means. At first, the apparatus comprises an arraying jig having a conductive ball insert section formed in a predetermined area, a ball cup having an opening in its lower face and capable of housing a multiplicity of conductive balls together with the arraying jig, and moving means for moving the ball cup along the upper face of the arraying jig. Secondly, the conductive ball arraying apparatus moves the ball cup housing the conductive balls, along the upper face of the arraying jig so that the conductive balls may fall into the insert section of the arraying jig and may be arrayed. Thirdly, the moving means moves the ball cup zigzag.
