System sealed, in particular for we shall now describe a sealed environment has been compromised and for determining if a housing of producing components is substantially free of the substance of the environment.

摘要

The invention relates to an apparatus intended to detect the introduction of the ambient substance in a case of electronic components, sealed with respect to the middle ambiant.le housing (11) comprises, in general, an electronic component (12) is covered or coated with plastic material. The introduction of a substance of the ambient medium in the case may be measured by one of several elements or monitoring sensors (16a, 16b), which detect the presence of this substance, and head of the rupture of the sealing of the case of components électroniques.domaine: cases of electronic components, in particular for aircraft and spacecraft, etc, 1 / p
