  • Patent number: 9880199
    Abstract: A probe for automatic test equipment (ATE) includes: an outer shroud including a course alignment feature configured to receive a target device and to guide the target device into an interior of the outer shroud, where the target device includes exposed electrical leads; and an inner structure that is at least partly inside the outer shroud. The inner structure includes electrical contacts for making an electrical connection to the exposed electrical leads, and also includes a fine alignment feature configured to guide the target device towards the electrical contacts to make the electrical connection.

  • Publication number: 20170059635
    Abstract: A test system includes a transporter having test sockets, where each test socket is configured to receive a device to be tested by the test system, and each test socket includes an element that is controllable to change a temperature of a device in the test socket through thermal conduction. The test system includes a test rack comprising slots. The transporter is configured for movement into, and out of, a slot of the test rack to test devices in the test sockets.

  • Publication number: 20130256967
    Abstract: An apparatus includes a body. The apparatus includes a test slot assembly configured to receive and to support a storage device for testing; at least one first vibration management element, disposed between the body and the test slot assembly and configured to disperse a first frequency vibrational energy. The apparatus includes at least one second vibration management element, disposed between the body and the test slot assembly and configured to disperse a second frequency vibrational energy, the first frequency vibrational energy having a first frequency that is above a second frequency of the second frequency vibrational energy.
