Latest Patents

Among his latest patents is the "Parallel test cell with self actuated sockets." This automated test equipment (ATE) features a test interface board assembly that includes a socket designed to provide electrical couplings from the test interface board to a device under test (DUT). The socket is uniquely configured to accept an active thermal interposer (ATI) device while the DUT is positioned within it. Additionally, the socket incorporates multiple spring-loaded roller retention devices that secure one or more devices in place. The ATE also includes a Z-axis interface plate that facilitates the opening of these retention devices for the insertion of the DUT and an ATI placement plate for the ATI device.

Another notable patent is the "Active thermal interposer device." This stand-alone device is intended for testing unpackaged integrated circuit devices. It features a body layer with a first surface that can be placed adjacent to a cold plate, and a second surface that contains several heating zones. These zones can be controlled by a thermal controller to selectively heat and maintain specific temperatures, allowing for precise testing of the DUT.
