  • Publication number: 20060100813
    Abstract: An apparatus for automatically inserting connectors and coupling test probes to circuit boards, such as computer system boards and the like. The apparatus enables connectors to be automatically inserted into mating connectors on a circuit board device under test (DUT). Connectors may be automatically inserted along 1-4 axes. The apparatus includes replaceable probe/connector plates that are DUT-type specific, as well as DUT-type specific side access units. The apparatus may also be used for inserting memory devices and microprocessors, and further enables peripheral devices to be operatively coupled to expansion bus connectors on the DUT. In one embodiment, a single actuator is employed to actuate up to four insertion axes simultaneously.

  • Publication number: 20060006894
    Abstract: Test modules, systems, and methods employing capacitors for the testing of the solder joint connections between a printed circuit board (PCB) and a socket of a device are presented in embodiments of the current invention. A test module having capacitors in parallel, and in particular embedded capacitors, can be used to test tied traces and their solder joint connections by measuring the total capacitance of the capacitors. Embodiments of the current invention present no-power tests that can be used with a variety of testing platforms and test fixtures, such as in-circuit testing (ICT) and manufacturing defect analysis (MDA.) Additionally, the test module can be used with a variety of sockets, such as a ball grid array, a pinned grid array, and a land grid array.
