  • Patent number: 8111080
    Abstract: An improved knee probe for probing electrical devices and circuits is provided. The improved knee probe has a reduced thickness section to alter the mechanical behavior of the probe when contact is made. The reduced thickness section of the probe makes it easier to deflect the probe vertically when contact is made. This increased ease of vertical deflection tends to reduce the horizontal contact force component responsible for the scrub motion, thereby decreasing scrub length. Here “thickness” is the probe thickness in the deflection plane of the probe (i.e., the plane in which the probe knee lies). The reduced thickness probe section provides increased design flexibility for controlling scrub motion, especially in combination with other probe parameters affecting the scrub motion.

  • Publication number: 20110273198
    Abstract: A vertically folded probe is provided that can provide improved scrub performance in cases where the probe height is limited. More specifically, such a probe includes a base and a tip, and an arm extending from the base to the tip as a single continuous member. The probe arm is vertically folded, such that it includes three or more vertical arm portions. The vertical arm portions have substantial vertical overlap, and are laterally displaced from each other. When such a probe is vertically brought down onto a device under test, the probe deforms. During probe deformation, at least two of the vertical arm portions come into contact with each other. Such contact between the arm portions can advantageously increase the lateral scrub motion at the probe tip, and can also advantageously reduce the probe inductance.

  • Patent number: 8040148
    Abstract: This invention relates to a system in package including a plurality of integrated circuit chips and a substrate on which the plurality of integrated circuit chips are mounted and characterized in that a testability circuit for facilitating a test on at least one of the integrated circuit chips is incorporated into the substrate. The testability circuit incorporated into the substrate is formed by embedding a so-called WLCSP integrated circuit chip into the substrate. Alternatively, the testability circuit is formed by using a transistor element formed by using a semiconductor layer formed on the substrate. By incorporating the testability circuit into the substrate as described above, it is possible to realize a system in package facilitated in test without increases in size and cost.

    Abstract: The voltage application probe and the voltage measurement probe are connected to the voltage application pad and the voltage measurement pad of the semiconductor device. The voltage application pad and the voltage measurement pad are connected by the conductor, measuring the voltage applied to the voltage application pad through the voltage measurement probe. The voltage compensation circuit in the voltage development device operates to make the voltage applied to the voltage application pad equal to the set voltage for the voltage development device. Even when the resistance between the voltage application probe and the voltage application pad increases, the accurate setting voltage is applied to the voltage application pad.

  • Publication number: 20110210759
    Abstract: A system and method for identifying opens among parallel connections on a circuit assembly such as a printed circuit board (PCB). In a learn phase performed on a known good circuit assembly, a group of parallel connected pins are excited with a first signal. A second signal, out-of-phase with the first signal, is applied to a second group of pins associated with the component. The amplitude and/or the phase of the second signal and the number and/or specific pins in the second group of pins are selected so that first and second signals coupled to a detector plate proximal to the component substantially offset. During a manufacturing test, signals of comparable amplitude and phase are applied to like pins on a like component of a circuit assembly under test. If the response signal coupled to a like detector plate is below a threshold, it is determined that each pin in the group of parallel connected pins is connected.
