[Dsg-ltcc] LTCC gas system

[Brian Eng]

So I finally saw the S4 flow turn on for the first time; also S1 has turned on as well so it is still leaking, albeit much improved. I still haven't seen S5 turn on yet.

So currently the LTCC leak rates look like the following (from worst [biggest leak] to best):

S2 > S6 > S3 > S1 > S4 > S5
