Highly sensitive hexafluoride check for leaks

Highly sensitive hexafluoride check for leaks

The inert gas sf 6 (sulphur hexafluoride) is used in component testing. As the gas cannot be found in ambient air, a highly precise and pure test result can be guaranteed. The new leak test unit virtually does "detective work" for it is able to trace smallest sf 6 leakages. Even leakage rates down to 1*10-9 mbar l/s can be easily detected.

  • Gas chromatographic detection of leaks in microelectronic

    This test is very sensitive and will detect leaks with rates from about 10-9 to 10-e cms of nitrogen (STP) per second. It fails, however, to distinguish between hermetic packages and those with gross leaks. This failure arises from the rapid diffusion of helium through a gross leak during the initial stage of the detection step. The bubble test has been applied to leaks larger than those detectable with the helium
