    摘要: 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.

    摘要: A disk time-sharing apparatus is constructed by a disk apparatus having disk drives, an input/output request unit for issuing an input/output request to the disk apparatus, and an input/output scheduling unit. The input/output scheduling unit forms input/output groups obtained by grouping inputs/output sources to/from the disk apparatus, defines a ratio of time during which each input/output group uses the disk apparatus, and decides quanta (allocating time) &tgr;1 to &tgr;3 during which each input/output group can use the disk apparatus continuously on the basis of the defined time ratio. When input/output requests are received to the disk apparatus from a plurality of input/output groups, a time-sharing for using the disk apparatus by switching the allocating time &tgr;1 to &tgr;3 sequentially among the competing input/output groups is performed.
