Abstract: A leak test apparatus and method is provided which includes an embodiment including a transparent container adapted to selectively permit a device under test to be placed therein, selectively maintain a vacuum, and contain an immersion liquid. The test apparatus further includes a test fixture plate adapted to remain fixed while the container moves along a first axis so as to permit the container to raise or lower with respect to the test fixture plate so as to raise or lower a test fluid with respect to the test fixture plate. The apparatus further includes a support structure adapted to raise or lower the container such that the test fixture plate remains fixed with regard to the container, a vacuum manifold system selectively coupled to the container, and a control system adapted to control raising or lowering of the container and control of vacuum in the container.
