Abstract: Disclosed is an interposer and test structure for making contact between a substrate and a test bed. One embodiment of the interposer has a floating, rigid conductive element in a nonconductive body which makes temporary contact between the test bed and the substrate. In another embodiment of the invention, the interposer includes two layers of material, in which one layer includes pogo pins for contacting the substrate and the other layer includes pads for contacting the test bed. The pogo pins are on a grid spacing corresponding to that of the substrate input/output pads while the interposer pads are on a grid spacing corresponding to that of the pogo pin contactors of the test bed.

Abstract: A fixture for testing circuits includes a rectangular array of conductive test pads, alternating with insulating areas in a checkerboard-like pattern. In a first embodiment, the entire array is printed on a central portion of a plastic membrane, with outer portions of the membrane carrying electrical lines from the test pads to connectors. In a second embodiment, the rectangular array is formed on surfaces of a number of closely packet plastic membranes, each of which has tabs extending away from the testing surface to connectors. The test fixture is generic, not being configured for testing a particular circuit configuration. To compensate for conditions of linear misalignment, the rectangular array is moved in a raster pattern having a size equal to the cell size of the rectangular array. To compensate for conditions of angular misalignment, the array may be rotated after such misalignment is measured, or test results may be compared with exemplary data for a number of misalignment conditions.

Abstract: A shorting pad probe tip for a substrate tester includes a compliant mandrel, a flexible conductive sheet and a nest plate. The flexible conductive sheet is loosely wrapped around the compliant mandrel. The compliant mandrel and flexible conductive sheet are secured together to the supporting nest plate. At least one side of the flexible conductive sheet is electrically conductive such that when the probe tip is brought in contact with the substrate to be tested, I/O pads on the surface of the substrate become electrically connected. In one embodiment the flexible conductive sheet is metallized polyimide.

Abstract: A method and apparatus for locating shorts in multi-layer electronic packages during manufacture allows repair of the shorts and improved yields of the packages. A multi-layer package is fitted in a fixture after forming a thin film layer of metalization, and test is performed to detect shorts in the package. If a short is detected, a low current, high frequency signal is injected in pins on a bottom surface of the package. An approximate two dimensional location of the short is sensed by detecting an electromagnetic force induced by a magnetic field inductively coupled to a sensor proximate to the short on a top surface of the multi-layer package. The approximate location of the short is then inspected to precisely locate the short.

Abstract: A front lifting system for vehicle comprises a threaded pipe, an annular hydraulic unit, and a fixing base. When the threaded pipe covers a shock absorber, a spring covers a damper of the shock absorber and two ends of the spring are respectively abutted against the annular hydraulic unit and the damper. At this time, the annular hydraulic unit does not act. When the annular hydraulic unit acts, it pushes the spring upwardly and further the spring pushes the damper upwardly so that the front of the vehicle may be lifted up to prevent the front of the vehicle with lower chassis from damage while going uphill or downhill.

Abstract: A micro-electrochemical sensor contains magnetic compounds inserted within a substrate that exert a magnetic force of attraction on paramagnetic beads held in contact with an electrode. The magnetic compounds can be contained within a fluid that is introduced into a void in the substrate. The electrode can be spaced apart from the magnetic compounds by a dielectric multi-layer membrane. During the fabrication process, different layers within the membrane-electrode structure can be tuned to have compressive or tensile stress so as to maintain structural integrity of the membrane, which is thin compared with the size of the void beneath it. During a process of forming the structure of the sensor, the tensile stress in a TiW adhesion layer can be adjusted to offset a composite net compressive stress associated with the dielectric layers of the membrane. The membrane can also be used in forming both the electrode and the void.
