    摘要: A semiconductor device-mounting construction including a semiconductor device having a plurality of electrodes formed on one main surface thereof. A printed circuit board having a writing pattern formed on one main surface thereof and a plurality of solder bumps interposed between the plurality of electrodes and the writing pattern to electrically connect the semiconductor device and the printed circuit board together. All of the voids, which are present in an interface of each of those of the plurality of solder bumps which are disposed closest to an outer peripheral edge of the semiconductor device, joined to the semiconductor device, are fine, and generally uniform in size.

    摘要: The present invention provides a trackball and an in-vehicle device controller using the trackball. The trackball provides a stable operational feel and is easy to operate even in an environment in a vehicle where vibration and movement are present. The trackball includes a ball made of a non-magnetic material and having embedded therein bar members made of a magnetic material and arranged on three axes orthogonal to one another, a case enclosing the ball such that at least an upper portion of the ball is exposed, magnetic members fixed to the case on two axes penetrating through the center of the ball and orthogonal to each other so as to allow magnetic coupling to ends of the bar members, and another magnetic member fixed to the case on an axis penetrating through the center of the ball and orthogonal to the two axes so as to allow magnetic coupling to an end of one of the bar members.
