    Abstract: A solder ball loading method capable of securely loading solder balls on connection pads includes applying flux on each connection pad group of a printed wiring board flux is not applied to a contact portion between a spacer and the printed wiring board to keep the flux from attaching to the spacer. Because the flux is not attached to the spacer, when the mask is detached from the printed wiring board, the printed wiring board need not be inverted, and damage to the solder resist layer 70 is minimized. Further, the heights of the solder balls and the upper surface of the mask are made equal by using the spacer, making it possible to securely load the solder balls on the electrode pads, one solder ball for each connection pad, and to reduce a probability that solder balls are not loaded or that a plurality of the solder balls are loaded onto a single connection pad.

  • Patent number: 7506792
    Abstract: A method and apparatus are disclosed for placing solder spheres on electronic receiving pads of a ball grid array (BGA) component package, such as by a BGA solder sphere placement apparatus. The solder spheres are held to a pattern of solder sphere apertures in a foil and against a solder sphere backing rib of a second layer by a vacuum holding force. After locating the solder spheres to receiving pads of a BGA component package, the system removes the holding force and the solder spheres are then released and placed on the receiving pads. Optionally, the apparatus can ensure release of the solder spheres as well as seating the solder spheres onto the receiving pads by applying a tapping or vibrational force.
