    • 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。
