Abstract: An apparatus for placing and mounting solder balls on an integrated circuit substrate contains: a fixture, a vacuuming device, a guiding plate, and a storage tank. The fixture includes a plurality of first grooves defined therein, the vacuuming device is disposed over the fixture and includes a vacuum chamber which has an air pore so that when air is drawn out of the vacuum chamber via the air pore, a plurality of solder balls are attached, and when the air is fed into the vacuum chamber from the air pore, the plurality of solder balls are released. The guiding plate is secured below the fixture, and the storage tank is arranged below the guiding plate and is applied to accommodate the plurality of solder balls. Thereby, a production yield of placing and mounting the plurality of solder balls on an integrated circuit substrate is enhanced.
Abstract: A method is used for implanting solder balls of an integrated circuit by operating a ball implanting machine. The ball implanting machine includes a suction fixture, an evacuating device, two pivoting and inverting devices, a guide plate, a ball carrier, and a substrate. The suction fixture has a plurality of ball grooves. The guide plate has a plurality of guide holes each aligning with a respective one of the ball grooves of the suction fixture. The ball carrier contains a plurality of solder balls. Thus, each of the solder balls is extended through the respective guide hole of the guide plate into the respective ball groove of the suction fixture, so that the solder balls will not protrude outward from the guide plate and will not interfere with or jam each other during movement of the ball carrier.
