Abstract: An apparatus includes a test chamber and a pressure-application structure. The pressure-application structure is configured to apply a force on a device under test within the test chamber in response to a vacuum being drawn in the test chamber. The force has a magnitude that is proportional to a difference between an external pressure outside the test chamber and an internal pressure within the test chamber.
