    Abstract: An apparatus for testing an object may include a test chamber, a first chamber, a second chamber, and a gas supply module. The test chamber receives a test board for testing an object. The first chamber is under the test chamber and receives a lower surface of the test board. The second chamber surrounds the first chamber to isolate the first chamber from ambient air. The gas supply module supplies a dry gas to the second chamber to provide a positive pressure higher than an ambient pressure, thereby preventing the ambient air from infiltrating into the first chamber. Thus, during the testing of the object at a low temperature, the second chamber may prevent the humid ambient air from infiltrating into the first chamber to prevent condensation of water on the lower surface of the test board.

    Abstract: Disclosed are a test chamber and a test apparatus having the same. The test chamber includes a test compartment configured to support a plurality of test boards, each being configured to secure a test object. The test chamber applies a test signal to the test object. The test chamber includes an inlet side and a discharge side, and a supply duct vertically extending along a height of the test compartment. The supply duct supplies the inlet side of the test compartment with the test fluid. The test chamber includes a fluid controller to uniformly control a distribution of a test fluid in the supply duct and uniformly supply the test compartment with the test fluid. The disclosed test chamber and test apparatus provide a uniform test temperature and thereby improve a test reliability of a test object such as a semiconductor or semiconductor package.
