    • A precision assembly (210) for positioning a device (226) includes a stage (260) that retains the device (226), a dual mover assembly (228) that moves the stage (260), and the device (226) along a movement axis (266), a measurement system (222) and a control system (224). The dual mover assembly (228) includes a first mover (262) that moves the stage (260) along the movement axis (266) and a second mover (264) that moves the device (226) along the movement axis (266). The second mover (264) is rigidly coupled to the first mover (262) so that movement of the first mover (262) results in movement of the second mover (264). Further, the total output of the dual mover assembly (228) along the movement axis (266) is equal to the sum of the movement of the first mover (262) and the movement of the second mover (264). The measurement system (222) measures a movement position along the movement axis (266). The control system (224) controls the dual mover assembly (228) utilizing the movement position. The control system (224) is designed to effectively decouple the control of the first mover (262) from the control of the second mover (264). Further, the control system (224) includes a quantization feedforward loop.
    • 用于定位设备(226)的精密组件(210)包括保持所述设备(226)的平台(260),使所述平台(260)移动的所述双推进器组件(228),以及沿着 运动轴(266),测量系统(222)和控制系统(224)。 双推动器组件(228)包括沿着移动轴线(266)移动平台(260)的第一移动器(262)和沿着移动轴线(266)移动设备(226)的第二移动器(264)。 第二移动器(264)刚性地联接到第一移动器(262),使得第一移动器(262)的运动导致第二移动器(264)的运动。 此外,沿着移动轴线(266)的双推动器组件(228)的总输出等于第一移动器(262)与第二移动器(264)的运动的总和。 测量系统(222)测量沿着移动轴线(266)的移动位置。 控制系统(224)利用移动位置控制双推动器组件(228)。 控制系统(224)被设计成有效地将第一移动器(262)的控制与第二移动器(264)的控制分离。 此外,控制系统(224)包括量化前馈回路。

    • A polishing apparatus (10) for polishing a device (12) with a polishing pad (48) includes a pad holder (50) and an actuator assembly (432). The pad holder (50) retains the polishing pad (48). The actuator assembly (432) includes a plurality of spaced apart actuators (438F) (438S) (438T) that are coupled to the pad holder (50). The actuators (438F) (438S) (438T) cooperate to direct forces on the pad holder (50) to alter the pressure of the polishing pad (48) on the device (12). At least one of the actuators (438F) (438S) (438T) includes a first actuator subassembly (440) and a second actuator subassembly (442) that interacts with the first actuator subassembly (440) to direct a force on the pad holder (50). The second actuator subassembly (442) is coupled to the pad holder (50) and the second actuator subassembly (442) rotates with the pad holder (50) relative to the first actuator subassembly (440).
    • 用于用抛光垫(48)抛光装置(12)的抛光装置(10)包括垫保持器(50)和致动器组件(432)。 垫保持器(50)保持抛光垫(48)。 致动器组件(432)包括多个间隔开的致动器(438F)(438S)(438T),其联接到所述垫保持器(50)。 致动器(438F)(438S)(438T)协作以引导焊盘保持器(50)上的力,以改变设备(12)上的抛光垫(48)的压力。 致动器(438F)(438T)(438T)中的至少一个包括与第一致动器子组件(440)相互作用的第一致动器子组件(440)和第二致动器子组件(442),以将力 垫座(50)。 第二致动器子组件(442)联接到焊盘保持器(50),并且第二致动器子组件(442)相对于第一致动器子组件(440)与焊盘保持器(50)一起旋转。

    • A seal assembly (44) for sealing a connector gap (274) between a connector (248) and a frame (258) includes a first subassembly (260) that seals the connector gap (274) and a second subassembly (262) that selectively seals the connector gap (274). With this design, the second subassembly (262) can seal the connector gap (274) in the event the first subassembly (260) fails and does not seal the connector gap (274). The second subassembly (262) can include a seal (382) that is movable between a first configuration (286) in which the seal (382) does not seal the connector gap (274) and a second configuration (288) in which the seal (382) does seal the connector gap (274).
