Learn more about the best practice of leak testing of hermetically sealed devices in microelectronics, sensor technology, and other industries.
- Method overview: Fine leak tests and gross leak tests with focus on helium fine leak test
- Helium fine leak test - from displayed leak rate to real leak rate
- Influences on the test result
- Sensor test – a case study
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.
The webinar explains the test sequence, the parameters which have an influence on the test result, will show simulations of tests and compare the simulations with test recipes defined in relevant regulations and real experiments.
