  • Patent number: 10101360
    Abstract: A test socket with a link and mount system is used to couple a device under test to a testing apparatus for quick and reliable testing of microchips post-production. The socket includes a pivoting link that connects to the DUT, an elastomer for biasing the link in a first preferred orientation, and a mount that operates as a fulcrum to rotate the link into engagement with the DUT. The mount includes projections that extend below a bottom surface of the socket, such that engagement of the mount with the test device at the projections translates the mount parallel to a diagonal support wall in the socket such that the mount is driven away from the bottom surface of the socket and also toward the elastomer. The socket includes a gap above the mount to allow for movement of the mount within the socket, eliminating the fixed arrangement and the non-compliant loads that accompany the engagement of the mount to the test apparatus.
    Type: Grant

  • Patent number: 9829506
    Abstract: A test probe assembly includes a first elongate electrically conductive plunger that extends from a proximal first plunger end to a distal first plunger end, and is defined in part by a central longitudinal axis. The first plunger has a first spring latch at the distal first plunger end. At least a portion of the first plunger has an arc with a first plunger outer contact point opposite the first spring latch relative to the longitudinal axis. The first plunger is disposed in a spring. The first plunger outer contact point in contact with the inner diameter of the spring, and the first spring latch engages at least a portion of the spring.
