    • An interconnection circuit includes a plated through hole having a plurality of electrically isolated segments with at least one of the plurality of electrically isolated segments coupled to a signal path and at least one of the electrically isolated segments coupled to ground. With this arrangement, the circuit provides a signal path between a first and a second different layers of a multilayer. By providing one segment as a signal segment and another segment as a ground segment the size and shape of the electrically isolated segments can be selected to provide the interconnection circuit having a predetermined impedance characteristic. The interconnection circuit can thus be impedance matched to circuit board circuits, devices and transmission lines, such as striplines, microstrips and co-planar waveguides. This results in an interconnection circuit which maintains the integrity of relatively high-frequency signals propagating through the interconnection circuit from the first layer to the second layer. The interconnect circuits can be formed by creating distinct conductor paths within the cylindrical plated through-holes using variety of manufacturing techniques including, but not limited to, broaching techniques, electrical discharge milling (EDM) techniques and laser etching techniques.
    • 互连电路包括具有多个电隔离段的电镀通孔,其中所述多个电隔离段中的至少一个耦合到信号路径和耦合到地的电隔离段中的至少一个。 利用这种布置,电路提供了多层的第一和第二不同层之间的信号路径。 通过将一个段作为信号段,另一个段作为接地段,可以选择电隔离段的大小和形状,以提供具有预定阻抗特性的互连电路。 因此,互连电路可以与电路板电路,器件和传输线(例如带状线,微带和共面波导)阻抗匹配。 这导致互连电路,其维持通过互连电路从第一层传播到第二层的相对高频信号的完整性。 可以通过使用各种制造技术(包括但不限于拉削技术,放电铣削(EDM)技术和激光蚀刻技术)在圆柱形电镀通孔内产生不同的导体路径来形成互连电路。

    • A manipulator for a test head connected to automatic test equipment through a heavy, inflexible cable. The manipulator includes a telescoping column assembly to which is mounted a vertical member. A cradle holding the test head is mounted to the vertical member. The cable is clamped at the vertical member to reduce the amount of force exerted by the cable on the test head. The cradle includes movable members to allow fine positioning of the test head, while maintaining the test head isolated from cable force. Course motion of the test head may be made by moving portions of the manipulator on the opposite side of the cable clamp from the test head. Precise positioning of the test head relative to a handling device is accomplished through a positioning mechanism at the interface between the test head and the handling device. To allow the positioning mechanism to operate, the manipulator has compliance which allows the test head to be forced into position by the positioning mechanism.
    • 用于通过重型,不灵活的电缆连接到自动测试设备的测试头的操纵器。 操纵器包括一个可伸缩的柱组件,其上安装有垂直构件。 夹持测试头的托架安装在垂直构件上。 电缆被夹紧在垂直构件上,以减少电缆施加在测试头上的力量。 支架包括可移动构件,以允许测试头的精细定位,同时保持测试头与电缆力隔离。 可以通过将操纵器的与测试头相对的电缆夹的相对侧上的部分移动来进行测试头的运动。 测试头相对于处理装置的精确定位是通过在测试头和处理装置之间的界面处的定位机构实现的。 为了允许定位机构操作,机械手具有允许通过定位机构将测试头压入到位的顺从性。

    • Axial tension is applied to an optical fiber that had been scored at the intended cleave location, wherein the axial tension is applied in a time-varying manner to maintain the stress intensity factor for crack on the fiber within an acceptable level to produce a stable crack growth at a reasonable rate to cleave the fiber without requiring polishing of the end surface. Careful control of the applied tension force with time acts to control the velocity of the propagating crack by maintaining substantially constant stress intensity factor. The applied axial tension force is reduced with time and/or crack growth (as crack propagates). As a result, the strain energy in the fiber material is released by formation of a single plane with an optical quality surface without requiring polishing. A substantially flat optical surface of enhanced optical quality is formed at the cleaved end of the optical fiber.
    • 将轴向张力施加到在预定的切割位置刻痕的光纤,其中以时变方式施加轴向张力,以将纤维上的裂纹的应力强度因子保持在可接受的水平内以产生稳定的裂纹 以合理的速率生长以切割纤维而不需要抛光端面。 随着时间的推移,仔细控制施加的拉力可以通过保持基本上恒定的应力强度因子来控制传播裂纹的速度。 所施加的轴向拉力随着时间和/或裂纹扩展而减小(如裂纹扩展)。 结果,通过形成具有光学质量表面的单个平面而不需要抛光来释放纤维材料中的应变能。 在光纤的切割端形成基本平坦的光学质量的光学表面。
