  • Probe station having multiple enclosures
    Publication number: 20080048693
    Abstract: A probe station for probing a test device has a chuck element for supporting the test device. An electrically conductive outer shield enclosure at least partially encloses such chuck element to provide EMI shielding therefor. An electrically conductive inner shield enclosure is interposed between and insulated from the outer shield enclosure and the chuck element, and at least partially encloses the chuck element.
