Abstract: Embodiments of the present invention provide testing systems with liquid cooled thermal arrays that can pivot freely in three dimensions allowing surfaces to be brought into even, level, and secure contact, thereby preventing air gaps between surfaces and improving thermal performance. In this way, more DUTs can be tested in parallel within a small test space, overall costs of the test system are reduced, and greater cooling capacity can be provided for testing high-powered devices. Gimbaled mounts can be disposed on a bottom surface of individual thermal interface boards (TIBs) of a test system, and/or on top of individual thermal heads of a thermal array (TA) having a common cold plate (or having multiple cold plates).

Abstract: Embodiments of the present invention provide a gimbaling socket structure that uses tension to bring a device under test (DUT) disposed in the socket into secure contact with a liquid cooled thermal array or the like to cool the DUT during testing. The gimbaling socket structure is secured to a tension spring and can move freely in 3 dimensions to bring the surfaces of the DUT and the thermal array (or components thereof, such as TEC/ATI layers) into even, level, and secure contact with each other, thereby preventing air gaps between surfaces and improving thermal performance. The even, secure contact between surfaces improves thermal cooling and reduces variation in cooling efficiency. In this way, more DUTs can be tested in parallel within a small test space, overall costs of the test system are reduced, and greater cooling capacity can be provided for testing high-powered devices.

Abstract: An automated test equipment (ATE) includes a test interface board assembly. The test interface board includes a socket configured to provide electrical couplings from the test interface board to a device under test (DUT). The socket is further configured to accept an active thermal interposer (ATI) device while the DUT is disposed in the socket. The socket includes a plurality of spring-loaded roller retention devices configured to retain one or more devices in the socket. The ATE further includes a Z-axis interface plate configured to open the plurality of spring-loaded roller retention devices to enable insertion of the DUT into the socket and an ATI placement plate configured to open the plurality of spring-loaded roller retention devices to enable insertion of the ATI device into the socket.

Abstract: In accordance with one embodiment of the invention, a load cup mechanism is provided for loading and unloading apparatus such as a CMP apparatus. The load cup mechanism, configured to load a work piece into and to unload a work piece from the apparatus, comprises a load cup arm configured to pivot about an axis between a load position aligned with the apparatus and an off-load position. A work piece platform is coupled to an end of the load cup arm and a plurality of lift fingers and a plurality of guide fingers, configured to support and center a work piece, are spaced about the work piece platform. A plurality of guide posts are spaced apart about the periphery of the work piece platform and are configured to align the work piece platform, in the load position, to the processing apparatus.
