| 20110089966 | APPARATUS AND SYSTEMS FOR PROCESSING SIGNALS BETWEEN A TESTER AND A PLURALITY OF DEVICES UNDER TEST - Apparatus is for processing signals between a tester and devices under test. In one embodiment, the apparatus includes at least one multichip module. Each multichip module has a plurality of micro-electromechanical switches between a set of connectors to the tester and a set of connectors to devices under test. At least one driver is provided to operate each of the micro-electromechanical switches. Other embodiments are also disclosed. | 04-21-2011 |

| 20100134134 | TEST ELECTRONICS TO DEVICE UNDER TEST INTERFACES, AND METHODS AND APPARATUS USING SAME - In one embodiment, a test system has a set of test electronics for testing a device under test (DUT). The test system also has at least one test electronics to DUT interface having a zero insertion force (ZIF) connector. Each ZIF connector has a ZIF connector to DUT clamping mechanism configured to i) apply a first orthogonal force to a probe card that interfaces with a DUT, by pressing the ZIF connector against the probe card, and simultaneously ii) exert at least one second orthogonal force on the probe card, the at least one second orthogonal force being opposite in direction to the first orthogonal force. | 06-03-2010 |
