Abstract:Based on the principle of hermetic packages of electronic components, the commonleak test methods are introduced. The recent development in the helium mass spectrometer leak testing method in MIL-STD-883 is analyzed. After that, the characteristics and requirements of the cumulative helium-mass test method are analyzed. And finally, the idea of the helium-mass detection based on the helium exchanging time constant(τHe) is discussed.
Keywords:helium-mass spectrum  seal  standard  test method
