  • Patent number: 11715915
    Abstract: An electrical connector for a multi-wire electrical cable includes two cable-side electrical contact elements including associated terminals to each of which is to be connected a wire of the electrical cable, and two output-side electrical contact elements which are spaced apart from the cable-side electrical contact elements and from each of which projects an electrical connector element via which an electrical connection can be established to a mating connector. An active electrical device is disposed between the cable-side contact elements and the output-side contact elements. The active electrical device is placed on the contact elements, such that the active electrical device is in electrical contact with each of the contact elements, and such that the cable-side contact elements and the output-side contact elements are electrically connected to each other. The output-side contact elements are separated and axially spaced apart from the cable-side contact elements.

  • Patent number: 9921263
    Abstract: The present document describes a connector for use with a harness under test by an automated test equipment (ATE). The harness is electrically connected to a reference. The connector comprises connection points having a layout, namely a connector layout, electronic identifiers and a switch. Each one of the electronic identifiers is connected to a respective one of the connection points. The switch is either for connecting the ATE to the reference via the electronic identifiers, either for connecting the ATE to the reference while bypassing the electronic identifiers.

  • Patent number: 9671458
    Abstract: A guided approach device for guiding together a first device (handler or tester) and a second device (including a test head for electronic components), including a latching device with a cylindrical pin socket for holding and fixing a front end of a catch pin. The latching device is connected to a linear displacement device such that the cylindrical pin socket may be displaced in a linear direction at least a short distance corresponding to a multiple of a length of a leading section of the catch pin, which may be inserted into the pin socket. Additionally or alternatively, the latching device is connected to a linear displacement device such that the latching element, a spring element and the pin socket may be displaced, with the catch pin engaged, in a linear direction by the linear displacement device, so that the first and second devices maybe moved relative to one another.

  • Patent number: 9410907
    Abstract: Test fixtures for testing layers of touch screen material and methods for using the same. Some test fixtures include first and second test beds that are movable relative to each other, an impedance measurement circuit, an electrical connector, a clamping actuator, and a processor, where the test fixtures and/or test fixture components are configured to secure a layer of touch screen material and measure the electrical impedance of at least one feature of the layer. Some of the present methods include securing a layer of touch screen material between test beds, calculating an electrical impedance of at least one feature of the layer, and releasing the layer from the test beds.

  • Patent number: 8471579
    Abstract: A method of measuring slider resistance of different types of row bar with a common tester comprises judging the type of the row bar, if the row bar is femto-type row bar, supplying a first voltage to the front pins, and supplying a second voltage that is unequal to the first voltage to the back pins, thereby obtaining resistances of the sliders; if the row bar is shunting-type row bar, supplying a third voltage to the front pins which contact the test pads, and supplying a fourth voltage that is unequal to the third voltage to the front pin that contacts the common test pad, thereby obtaining resistances of the sliders. The present invention can measure two different types of row bar with a same common tester, which can reduce the downtime of machine and the manpower, and prevent the probe card from being damaged without a frequent disassembly and switch.

  • Patent number: 8330482
    Abstract: An embodiment test system is proposed; the test system is used to test electronic devices each one having a case with a plurality of terminals for example, of the BGA type. The test system includes a set of (one or more) test boards. Each test board includes a plurality of banks of electrically conductive receptacles, each one for resting a corresponding electronic device; each receptacle is adapted to receive a terminal of the corresponding electronic device. A set of (one or more) boxes is arranged in operation above the test boards. Each box defines an expandable chamber for a conditioning fluid; particularly, the box includes a rigid body, a flexible membrane of a thermally conductive material facing the test boards, an inlet, and an outlet. Means is provided for controlling a temperature of the conditioning fluid (for example, a heat exchanger).
