High Sensitivity Helium Leak Detection HSHLD™


HSHLD + Test combiné Grosses Fuites sèche + Fines Fuites Hélium ... E-11 atm·cm3/s. Compliant to Mil-Std 750-A1 Method 1071 Condition H1, H2 and H3. Compliant to Mil-Std 883K Method 1014 Condition A1, A2 and A5.

Seal integrity testing is crucial for hermetic packages in military, space, and commercial applications. A loss of hermeticity is a reliability concern and will allow moisture and contaminants to enter the package cavity shortening device lifetime.

Fine Leak

ORS performs seal testing per Mil-Std 883 method 1014 conditions A1 and C1, Mil-Std 750 method 1071 conditions H1 and C, Mil-Std 202 Method 112 conditions C, D, A and E, and client specific requirements. Testing is also performed per Telcordia GR-1221-CORE and GR-468-CORE for passive and active devices.

First, devices are preconditioned in a pressurized helium chamber for a given period of time. Then, the helium leak rate is measured and recorded, applying pass/fail criteria. Devices that are sealed with a known concentration of helium don't necessarily need to be pressurized.

Extended Fine Leak for Other Gases

Specialized leak testing is available for determining leak rates for gases other than helium. Leak rates of various gases (i.e. Argon, CO2, Acetic Acid, Ethylene Glycol, etc...) may be measured at low leak rates utilizing a mass spectrometer tuned specifically for the particular substance of interest.
