  • Publication number: 20090255098
    Abstract: In an embodiment, there is disclosed a clamp, having a housing; a latch member extending from within the housing, and the latch member translatable along a displacement axis; an actuator mounted to the housing and operatively associated with the latch member to translate the latch member along the displacement axis; and a nonlinear biasing member operatively associated with the latch member and the housing, and the nonlinear biasing member positioned to bias the latch member toward a retracted position. Other embodiments are also disclosed.

  • Patent number: 7541822
    Abstract: A cartridge (10) includes a chuck plate (12) for receiving a wafer (74) and a probe plate (14) for establishing electrical contact with the wafer. In use, a mechanical connecting device (90) locks the chuck plate and the probe plate fixed relative to one another to maintain alignment of the wafer and the probe plate. Preferably, electrical contact with the wafer is established using a probe card (50) that is movably mounted to the probe plate by means of a plurality of leaf springs (52.) The mechanical connecting device is preferably a kinematic coupling including a male connector (94) and first and second opposed jaws (122, 124.) Each of the jaws is pivotable from a retracted position in which the male connector can be inserted between the jaws and an engaging position in which the jaws prevent withdrawal of the male connector from between the jaws. The male connector is movable between an extended and a retracted position, and is biased towards the retracted position.

  • Patent number: 7460371
    Abstract: In one embodiment, there is disclosed apparatus having a printed circuit board (PCB); a heat sink device for disposition adjacent the bottom surface of the PCB; at least one wiffle tree component disposed adjacent the top surface of the PCB, having a base portion with a plurality of legs extending therefrom; and at least one mechanism to generate a clamping force between the at least one wiffle tree and the top surface of the PCB, and between the bottom surface of the PCB and the heat sink. There is disclosed a method of attaching a printed circuit board (PCB) to a heat sink. In an embodiment, the method includes providing at least one wiffle tree component; disposing one of the at least one wiffle tree component adjacent to the PCB; and securing the one of the at least one wiffle tree component with a fastener. Other embodiments are also disclosed.

  • Patent number: 6787718
    Abstract: An elongated sensor is provided for detecting the presence of a liquid in an electronics system. The sensor includes an elongated sensor element having a pair of adjacent electrical conductors, and a liquid permeable material that when dry electrically insulates the conductors, and when wet with a liquid at any point along the length of the conductors allows electric coupling of the conductors. The sensor also includes a detector operable to detect the presence of the liquid by sensing the electrical coupling of the conductors.
