  • Publication number: 20020181161
    Abstract: An actuator assembly including one or more actuator arms, wherein each of the actuator arms defines a clasp hole and a clamp-opening hole and a slot running between the clasp hole and clamp-opening hole, and optionally, a second slot running from the clasp hole to a distal end of the actuator arm, thereby creating two clasp fingers. A flex suspension assembly is included with a protrusion, such as a boss and a head on a distal end. The flex suspension assembly is coupled to the actuator arm by resiliently increasing the diameter of the clasp hole so as to allow the boss on the flex suspension assembly to be inserted into the clasp hole. With the boss is inserted, the clasp hole is allowed to revert to its original diameter, thereby clamping the boss in the clasp hole. A method for assembly is also provided.

  • Publication number: 20020075597
    Abstract: The present invention relates to a method and apparatus for folding a thin part such as the tail of a Flexible Circuit On Suspension or Traces Suspension Assembly that are used in a disc drive. The method comprises securing a portion of the thin part and then directing a fluid at the thin part to bend an unsecured portion of the thin part relative to the secured portion of the thin part. The apparatus comprises a fixture for securing the thin part and a fluid emitter positioned near the fixture to direct a fluid at the thin part such that the fluid bends the thin part relative to the fixture. The method and apparatus of the present invention are much more efficient than manually folding thin parts and eliminate any harmful contact between the thin parts and moving tools during the folding operation.
