ITRS – 22 Nanometer Mode
These findings are in regard to 22 nm circuitry, which is currently in design for 2011-2012. For this circuitry we will be concerned with all particles >10nm. There are some new issues that may reveal a need for cleaner, torque elimination metal face seal fittings. One new challenge is that with these extremely small geometries,…
Mil Std 810E – Seal Integrity Study
Mil Std 810E is designed to check the seal integrity of equipment under transportation shock & vibration. This study was performed by Applied Materials at Quanta Labs . The vibration phase was conducted for 3 hours which is designed to simulate 3000 miles of transportation. The fittings glands were clamped into the fixture before tighten…
OmniSafe Particle Study – Stainless Steel Gaskets
Stainless steel gaskets are required in certain gas systems such as carbon monoxide, ozone, and trimethyl arsenic. Because SS gaskets are harder than nickel, the torque induced problems of sealing and galling are amplified. Due to the SS sealing problems, some companies have specified silver plated SS gaskets to reduce friction and galling. Recently these…
OmniSafe Flight Qualification
Omnisafe works better than any other fitting for semiconductor applications and has been flight qualified and selected for the following aerospace programs. MSL Mars Rover – launch 2011, for the liquid Freon heat rejection system, Omnisafe 3/8” fittings JPL DAWN – Xenon Ion Propulsion, Asteroid Belt, Oct 2007, Omnisafe 1/8” fittings NASA Evolutionary Xenon…
Total Fitting Cost in an Assembly
This graph shows the installed cost of an Omnisafe vs the legacy metal face seal fitting. For either fitting, the purchase price is based on quantity. The additional labor cost of legacy fittings occur while trying to keep the components in alignment, undamaged, and leak tight during gas system assembly. Cost avoidance due to torque…
The Mechanics of Metal Seal Formation
Tribology is the study of friction, lubrication, and wear. Formally defined, it is the science and technology of interacting surfaces in relative motion. A face seal fitting that transfers torque to the sealing surfaces during the compression that creates the seal, has a fundamental flaw. A tribological study of metal seals shows that this rotation…
