Liquid cooled thermal arrays for testing devices under test
A recently filed patent (Publication Number: US20240036104A1) describes a test system designed for testing devices under test (DUT). The system includes a test interface board (TIB) and a socket interface board (SIB) with a gimbal mount that securely fixes the SIB to the TIB. The SIB features a socket to receive the DUT and a thermal array to regulate the temperature of the DUT during testing. Additionally, a superstructure surrounds the DUT when placed in the socket, with an interposer in contact with the DUT to enhance the testing process.
Furthermore, the patent details various configurations and components of the test system, such as a self-actuating socket (SAS) and parallel socket actuation (PSA) socket. The system can accommodate multiple DUTs simultaneously, with gimbal mounts aligning the DUTs with the thermal array for efficient testing. The thermal array itself comprises a gimbal mount, a thermal head, and a fixed tray with a socket for housing the DUT. The thermal head can pivot freely in three dimensions to ensure optimal contact with the DUT for precise temperature regulation during testing. Overall, the patent outlines a comprehensive test system with innovative features to enhance the testing process for electronic devices.
