Patent number: 12411167Abstract: 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.Type: GrantFiled: August 16, 2023Date of Patent: September 9, 2025Assignee: Advantest Test Solutions, Inc.Inventors: Gregory Cruzan, Karthik Ranganathan, Gilberto Oseguera, Joe Koeth, Paul Ferrari, James Hastings, Chee Wah Ho

Patent number: 12235314Abstract: 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.Type: GrantFiled: July 29, 2022Date of Patent: February 25, 2025Assignee: Advantest Test Solutions, IncInventors: Karthik Ranganathan, Gilberto Oseguera, Gregory Cruzan, Joe Koeth, Ikeda Hiroki, Kiyokawa Toshiyuki

Patent number: 12210056Abstract: 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).Type: GrantFiled: October 10, 2023Date of Patent: January 28, 2025Assignee: Advantest Test Solutions, Inc.Inventors: Gregory Cruzan, Karthik Ranganathan, Gilberto Oseguera, Joe Koeth, Paul Ferrari, James Hastings, Chee Wah Ho
