Vacuum immersion test set

摘要

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.

主权项

1. A leak test apparatus comprising:
a first structure comprising a support structure; a second structure comprising a transparent container adapted to selectively open to permit insertion of a device under test therein, maintain a vacuum, and contain a liquid without leakage up to a predetermined pressure differential; a test fixture plate adapted to remain fixed with respect to the first structure, wherein said test fixture plate and first structure are adapted to permit raising or lowering of the second structure so that said second structure raises or lowers the liquid with respect to the test fixture plate, wherein said test fixture plate is adapted to support the device under test that is subjected to an immersive leak test procedure; an actuator and moveable support structure adapted to raise or lower said second structure such that said test fixture plate remains fixed with regard to said first structure; a vacuum manifold system coupled to said second structure including a flexible portion adapted to enable coupling between said manifold system and said second structure; and a control system adapted to control said actuator operation of raising or lowering of said second structure and connecting of said manifold system to a vacuum source adapted to create a vacuum in said second structure up to a first pressure differential between an atmosphere outside said second structure and within said second structure.
