Bombing - Leak Test Of Hermetically Sealed Objects

Testing of hermetically sealed objects, like encapsulated electronics or batteries, often puzzles operators. This is due to poor repeatability of the test and discrepancies between the displayed test results and real leak rates. Repeatability of the test is influenced by a potential change of the tracer gas amount inside the unit under test. The test result is influenced by parameters like exposure time, bombing pressure, and waiting time between end of helium pressurization and leak test.

This webinar explains the test sequence, identifies the parameters which have an influence on the test result, shows simulations of tests, and compares the simulations with test recipes defined in relevant regulations and real experiments.
