Abstract: Devices are provided herein in a variety of examples that inhibit particle pickup and transport and mechanical vibrations and provide other advantages. In one illustrative example, an actuator assembly includes a base, an actuator disposed on the base, and a shroud disposed on the base around the actuator. The shroud includes one or more shroud walls disposed between the actuator and a flow channel exterior to the shroud. The shroud walls may include shielding walls that partially surround the actuator, radially curved shroud wall segments, fastener well shields that substantially separate an interior thereof from the actuator, and other aspects. A data storage device may have a flow path defined therein, and the shroud may be disposed around an actuator within the data storage device, providing a streamlined surface between the flow path and the actuator.

Abstract: An assembly includes a housing with a base. A mounting pad is positioned on the base. The assembly also includes a micromechanical device coupled to the mounting pad. First and second side rails extend from the base to form first and second rail corners. The first and second rail corners are subject to striking a surface. The first and second rail corners have first and second elevations that are uneven to reduce impacts reaching the micromechanical device.
