摘要： A method for detecting a leak in a test object, including inserting the test object into a test chamber; filling the test object with a test gas; and adjusting a pressure in the test chamber and a pressure in the test object such that the test chamber pressure is lower than the test object pressure. The test chamber contains air and the test object is filled exclusively with a gas containing no molecules with oxygen atoms. In order to detect a leak in the test object, an oxygen proportion of the air in the test chamber is measured with an oxygen sensor.

摘要： A method for helium mass spectrometric fine-leak test is based on quantitative determination of maximum test-waiting time, which gives a method for quantitative determination of the maximum test-waiting time for fine-leak test during a helium mass spectrometric test process of the sealability, and gives a method for determining the criterion for measured leak rate by taking the minimum helium gas exchange time constant, i.e., a rigour grade τHemin, of an acceptable sealed electronic component as a basic criterion for helium mass spectrometric fine-leak test. Based on the inventive method for quantitative determination of the maximum test-waiting time, for most of the cavity volume ranges, the maximum test-waiting time that is determined accurately may be much longer than 1 hour or 0.5 hour as determined qualitatively by the existing related standards.

摘要： Systems, methods, and apparatus are provided for detecting improperly sealed portions of sealed packages. For example, in one embodiment, a package leak detection system automatically provides pressure within a tank for a predetermined period of time. The tank is at least partially filled with colored fluid with a sealed package being at least partially submerged in the colored fluid. In the tank, the pressure inside the tank forces the colored fluid into improperly sealed portions of the sealed package. After the predetermined period of time has elapsed, the package leak detection system automatically shuts off the package leak detection system and releases the pressure within the tank so the sealed package can be inspected for potential leaks.

摘要： A system for detecting leaks in a unit. The novel system includes a first mechanism for injecting a first gas into an interior or an exterior of the unit, a second mechanism for sampling gas from an exterior or an interior of the unit to determine if the first gas has leaked out of or into the unit, respectively, and a third mechanism for controlling a differential pressure between the interior and exterior of the unit during sampling. In an illustrative embodiment, the differential pressure is controlled by injecting a second gas into the exterior or interior of the unit to replace the sampled gas, and using pressure regulators to control the pressures of the first and second gases such that the differential pressure remains constant during sampling.
