  • Patent number: 8144432
    Abstract: An actuator for selectively positioning a portion of a communication channel formed by a cable circuit having a protuberant component connected at a proximal end to a flexible base, whereby the actuator defines a heat transfer surface operably disposed in thermal conductivity with a distal surface of the protuberant component for sinking heat from the component to the actuator.
    Type: Grant

  • Patent number: 8111485
    Abstract: An actuator for supporting data transfer elements includes an arm, a flexible circuit assembly and a sensor. The flexible circuit assembly includes a stiffener having a mount feature and a turnaround feature. The flexible circuit assembly also includes a flexible cable having a plurality of conductive traces for electrically connecting the data transfer elements to circuitry. The flexible cable has a service loop portion, a mounting portion coupled to the mount feature of the stiffener and a turnaround portion coupled to the turnaround feature of the stiffener. The turnaround portion is configured to couple the mounting portion to the service loop portion. The sensor is in contact with a surface of the arm and is electrically coupled to the flexible cable.

  • Patent number: 7952834
    Abstract: In accordance with various embodiments, a printed structure of a flex circuit assembly includes a plurality of adjacent land portions formed on a heat conductive stiffener member and which support electrically conductive paths for connection to an integrated circuit. A corresponding plurality of separation channels are formed between the adjacent electrically conductive paths, and thermal energy generated by operation of the integrated circuit is transferred through the separation channels to the stiffener member. In some embodiments, the separation channels retain a fluid, such as air or a low density inert gas, which flows through the separation channels in response to rotation of a rotatable member adjacent the flex circuit assembly. In other embodiments, a dielectric, thermally conductive material fills the separation channels.

  • Patent number: 7646567
    Abstract: A FOS is provided for electrically connecting a data transfer head with a PCCA. The FOS comprises a polymeric layer supporting an electrical trace. The electrical trace comprises an uninsulated pad surface configured for electrically engaging a solder interconnect of the PCCA. The polymeric layer comprises a continuous portion covering the pad and opposing the pad surface. A method is provided comprising providing the FOS comprising the electrical trace and the polymeric covering, contactingly engaging the pad surface portion of the trace with the solder interconnect portion of the PCCA, and conducting heat through the polymeric covering to reflow the solder interconnect, thereby electrically connecting the FOS to the PCCA.
