Did you do that for components in tape and reel packaging, or out of it?

As A Note I recall a discussion long ago that vacuum does not speed up water diffusion.
Does anyone recall? The rate of diffusion was more dependent on the concentration difference and temperature.

You might want to check out this paper:
Characteristic Times of Moisture Diffusion and Bake-out Conditions for Plastic Encapsulated Parts written by Alexander Teverovsky QSS Group, Inc./Goddard Operations [log in to unmask]
I have emailed you a copy. Of note is that the key temperature for any bake out under vacuum is 58C.
