    • A membrane probing assembly includes a support element having an incompressible forward support tiltably coupled to a rearward base and a membrane assembly, formed of polyimide layers, with its central region interconnected to the support by an elastomeric layer. Flexible traces form data/signal lines to contacts on the central region. Each contact comprises a rigid beam and a bump located in off-centered location on the beam, which bump includes a contacting portion. After initial touchdown of these contacting portions, further over-travel of the pads causes each beam to independently tilt locally so that different portions of each beam move different distances relative to the support thus driving each contact into lateral scrubbing movement across the pad thereby clearing away oxide buildup. The elastomeric member backed by the incompressible support ensures sufficient scrub pressure and reliable tilt recovery of each contact without mechanical straining of the beam. In an alternative embodiment, the contacts comprise conductive beams each supported on a loose U-shaped flap formed in the membrane assembly where each flap and beam is tiltably supported in inclined position by an elastomeric hub interposed between the flap and support.
    • 膜探测组件包括支撑元件,其具有可倾斜地联接到后部基座的不可压缩的前部支撑件和由聚酰亚胺层形成的膜组件,其中心区域通过弹性体层互连到支撑件。 灵活的轨迹可以形成数据/信号线到中心区域的触点。 每个触点包括刚性梁和位于梁的偏心位置的凸块,该凸起包括接触部分。 在初始接触这些接触部分之后,垫的进一步过度行进导致每个光束独立地局部地倾斜,使得每个光束的不同部分相对于支撑件移动不同的距离,从而将每个触点驱动穿过焊盘的横向擦洗运动,从而清除 氧化物积聚。 由不可压缩支撑件支撑的弹性体构件确保了足够的擦洗压力和每个接触件的可靠的倾斜恢复,而不会使梁的机械应变。 在替代实施例中,触头包括各自支撑在形成在膜组件中的松散的U形舌片上的导电梁,其中每个翼片和梁通过插入在翼片和支撑件之间的弹性体毂倾斜支撑在倾斜位置。

    • A multi-use lawn mower capable of operating as a mulching, side-discharge, or a bagging mower. The lawn mower (10) includes; a mower deck (14) having an opening (58) therein forming a passageway through which grass clippings exit the cutting chamber during select modes of operation. The lawn mower also includes a grass-collecting hopper (40) removably mounted on the mower deck (14), the grass-collecting hopper (40) having a basket portion (42) for receiving grass clippings cut by the cutting blade (36) and a multi-station mounting portion (60) configured to interface with the opening (58) in the mower deck in a plurality of orientations. The mounting portion includes a mulching station (64) that configures the lawn mower to function as a mulching mower, a bagging station (66) that configures the lawn mower to function as a bagging mower, and a side-discharge station (68) that configures the lawn mower to function as a side-discharge mower. When the multi-station mounting portion mounts the grass-collecting hopper on the mower deck, a single one of the stations interfaces with the opening in the mower deck to configure the lawn mower for desired mode of operation.
    • 一种多用途草坪割草机,能够作为覆盖,侧面排放或装袋割草机操作。 割草机(10)包括 在其中具有开口(58)的割草机甲板(14)形成通道,在选择操作模式期间,草屑通过该通道离开切割室。 草坪割草机还包括可拆卸地安装在割草机甲板(14)上的集草料斗(40),集草料斗(40)具有用于接收由切割刀片(36)切割的草屑的筐部分(42) 以及多工位安装部分(60),其构造成以多个取向与割草机甲板中的开口(58)相接。 所述安装部分包括:配置所述割草机以覆盖覆盖的割草机的覆盖站(64),将所述割草机配置为装袋割草机的装袋站(66)以及排放站(68) 将割草机配置为侧放式割草机。 当多工位安装部分将草地收集料斗安装在割草机甲板上时,单个一个工位与割草机甲板上的开口接合,以将草坪割草机配置为所需的操作模式。

    • A reusable test socket is described for testing fine pitch devices including singulated bare die, semiconductor wafers, chip sized packages, printed circuit boards, and the like to determine that the fine pitch device is not faulty. The socket contains a circuit pad pattern in the mirror image of the pattern of contact points, usually bond pads of the fine pitch device to be tested. Each pad of the socket contains a conductive elastomeric probe which has been "screened" onto the bond pad. The socket also contains an alignment template for orienting the fine pitch device onto the elastomeric probes of the contact point pattern of the test socket. Additionally, the socket can be a singular piece or it can be made of two main pieces; the first being a socket, and the second being a test board designed to mate with the socket. The disclosed invention also includes a method of using the reusable test socket which includes the steps of placing the fine pitch device onto the test socket, placing the socket into electrical continuity with test equipment and conducting electrical tests at ambient as well as elevated temperatures.
    • 描述了一种可重复使用的测试插座,用于测试包括单片裸芯片,半导体晶片,芯片尺寸封装,印刷电路板等的细间距器件,以确定精细间距器件没有故障。 插座包含接触点图案的镜像中的电路焊盘图案,通常是要测试的细间距器件的接合焊盘。 插座的每个垫包含已经“屏蔽”到接合垫上的导电弹性体探针。 插座还包含用于将细间距装置定向到测试插座的接触点图案的弹性体探针上的对准模板。 此外,插座可以是一个单一的部分,也可以由两个主要部分组成; 第一个是插座,第二个是设计为与插座配合的测试板。 所公开的发明还包括使用可重复使用的测试插座的方法,其包括以下步骤:将细间距装置放置在测试插座上,将插座与测试设备电连接并在环境温度和升高的温度下进行电测试。
