    摘要: A brushless motor includes a stator having a stator core, a rotor, a circuit board, a board holder for holding the circuit board, a motor housing having a notch at an opening, and a housing cover. The motor housing accommodates the stator, the rotor, and the board holder to which the circuit board is mounted, and the motor housing is sealed with the housing cover. The board holder includes a board mount section, a lead-wire holder for holding lead-wires. The lead-wire holder is placed at the notch of the motor housing. The lead-wires extend from the circuit board mounted to the board mount section to the outside of the motor housing via the lead-wire holder.

    摘要: The present invention provides a disk drive device that can appropriately clamp a disk by means of magnetic force even when the disk drive device is very small. A clamping magnet 16 on which a disk 20 is mounted is attached to a turntable portion 15b of a rotor frame 15 to attract the disk 20. The clamping magnet 16 is configured so that the disk 20 can be mounted on the clamping magnet 16. An area of the rotor frame 15 from the turntable portion 15b to a boss portion 15a is composed of a ferromagnetic material.

    摘要: A mounting structure 1 in which an electronic component 5 is surface-mounted with solder 4 to a wiring substrate 2 is disclosed. The solder is Sn—Ag—Bi—In-based solder containing 0.1% by weight or more and 5% by weight or less of Bi, and more than 3% by weight and less than 9% by weight of In, with the balance being made up of Sn, Ag and unavoidable impurities. The wiring substrate has a coefficient of linear expansion of 13 ppm/K or less in all directions. Thus, it is possible to realize a mounting structure using lead-free solder and for which the occurrence of cracks in a solder joint portion due to a 1000-cycle thermal shock test from −40 to 150° C. has been suppressed.

    摘要: The object of the present invention is to provide a solder paste that enables to form a surface mounting structure for electronic components that exhibits crack resistance in a solder joint section even in 100 heat-shock cycles at −40° C. to 150° C. as required for use in the vicinity of engines for vehicular applications. A flux including an amine halogen salt and a dicarboxylic acid is kneaded with a Sn—Ag—Bi—In alloy powder. As a result, a solder paste exhibiting long continuous printability, little occurrence of solder balls, and excellent joining ability with no cracking in 100 heat-shock cycles at −40° C. to 150° C. is obtained.
