  • Patent number: 7871289
    Abstract: A printed circuit cable assembly for top down installation in a disc drive or the like in which a printed circuit cable supporting electrical conductor paths has a body portion, a flex portion and an insertion tab connecting the body portion and flex portion. A PCC support member having a support ramp extending into a slotted gap supports the printed circuit cable with the insertion tab extending into the slotted gap so that the flex portion is extended for attachment to a moveable article, such as the head stack assembly of a disc drive. Preferably, the PCC support member has an indexing bore, and the PCC support member with the supported printed circuit cable is mounted to a support member having an indexing post, the PCC support member positioned so that indexing bore is positioned over the indexing post.

  • Patent number: 7730791
    Abstract: A test device comprises a base and a first fixture coupled to the base. The first fixture holds a first portion of an electronic device mounted in the test device. The test device includes a second fixture rotatably coupled to the base and a lever coupled to the second fixture. The second fixture holds a second portion of the electronic device mounted in the test device. The test device also includes an actuator that forcibly moves the lever to rotate the second fixture and apply a torsion stress on the electronic device mounted in the test device. The test device may be used to test the functionality of electronic devices, such as small form-factor disc drives, while under torsion stresses.
