  • Shaped internal leads for a printed circuit substrate
    Patent number: 9288905
    Abstract: A printed circuit substrate may be configured with at least one internal lead designed and shaped to reduce solder bridging. The printed circuit substrate can have a plurality of internal leads that each has a continuously curvilinear boundary that defines an isolation channel. The isolation channel may be configured with a uniform distance that separates a first internal lead from an adjacent second internal lead.

  • COLLAPSIBLE TOLERANCE RINGS WITH WEAK POINTS
    Publication number: 20130163912
    Abstract: In certain embodiments, a method includes positioning a tolerance ring between a bearing assembly and an actuator arm. The tolerance ring is compressed so that the tolerance ring buckles at predetermined weak points to position the bearing assembly relative to the actuator arm. In certain embodiments, an assembly includes a tolerance ring buckle-fitted between first and second annular surfaces, the tolerance ring buckled at designated weak points to position the first annular surface to the second annular surface.
