摘要： 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.

摘要： 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.

摘要： 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.
