摘要:
The present invention relates to a ball capturing apparatus and method of capturing one ball from plural balls having the same size, and to a solder ball disposing apparatus and method of disposing a solder ball containing solder in a predetermined position on a circuit board, thereby reliably capturing one ball from the plural balls having the same size. The apparatus includes: a holding member 111 including a holding wall 111a air-tightly closing a space S that holds a plurality of balls B having the same size and in which a hole 1111 larger than a size of one ball and smaller than a size of two balls is formed in an upper part of the holding wall; blowup means 112 for blowing the balls B held in the holding member 111 upward; and capturing means 12 for capturing a ball B blown up by the blowup means 112 and reached the hole.
摘要:
A method and a apparatus for removing a micro component surely and leveling solder remaining on a substrate without imposing thermal damage to solder lands, the substrate and components on the periphery. A thermosetting adhesive (15) is provided on the surface (12a) of a micro component (12) opposite to the side of a substrate (11), and the distal end of a component holding pin (13) having cross-section area falling within the surface (12a) of the micro component (12) opposite to the side of the surface (11) is passed through the thermosetting adhesive (15) to abut against the surface (12a) of the micro component (12). Subsequently, solder (16) between the micro component (12) and the substrate (11) is heated to melt and the component holding pin (13) is moved in the direction receding from the substrate (11). Consequently, the micro component (12) is removed from the substrate (11).

Disclosed is a board reinforcing structure for reinforcing a circuit board in which an electronic component is mounted on a first surface, the electronic component having an electrode arranged in a rectangular-shaped region on the first surface. The board reinforcing structure includes a reinforcing member bonded to positions corresponding to corner parts of four corners of the rectangular-shaped region on a second surface provided on a side opposite to the first surface of the circuit board. In the board reinforcing structure, corresponding one of notches is formed in the reinforcing member at a position corresponding to one of the corner parts of the four corners of the rectangular-shaped region, and at least two apexes of the reinforcing member directed to an outside are formed to shape a contour thereof with the one of the notches.
