Jim,
The He and H2 can depart from inside the device just as easily as they
entered, so if put back in a normal environment, the diffusion will
reverse and eventually stop at a new equilibrium point. If the parts are
exposed to the nice high vacuum of free space, they should ultimately be
Hi Jim:
When I was working in Semiconductors we used a fluorocarbon liquid in a heated fish tank first. If bubbles come out you
have a "gross" leak. After that we put a whole bunch of parts in a 5 gallon paint pot and pressurized it with He and
let them soak. Then a small number of parts
There was discussion last October about the very tiny MEMS oscillators
failing from He leaking in. By now, there's several videos online
showing folks taking that MEMS oscillator and putting it in a chamber
and demonstrating the failure.
So here's something interesting - There are a
