Ahhh, vapor phase. Damn, I LOVE that technology. I did some qualifying stuff for
Halliburton in Houston with Claude Howland and Larry Tawyea . NO!!! Thank YOU

Outstanding Jason,

I did a bunch of downhole stuff some years ago. Mostly, we used LCCC's
soldered using vapor phase. You probably know the folks as Slumburger
(sorry) bought Quantum Solutions. We used polyimide and reasonable pad
designs with vapor soldering and no outside interference. I guess we
eliminated the need for conventional soldering or nitrogen soldering
processes. Also, Quantum folks came up with a semi-soft potting solution.
Some of the boards are reported to be still in operation today after many years.

Thanks for the memories Jason,

Earl
