MSD's need baking only if they have exceeded their exposure limits.
We use a McDry for Reeled parts.
Periodically, we need to remove the parts from T+R, bake, then put them
in tubes or trays.

The best thing to do is control the exposure time if possible.

Subject: [TN] Moisture sensitive Components

Good Day Technet:
Being a military OEM, we've never had to use plastic components but
we're just starting to use them.  I'm embarrassed by the amateurish
nature of this question, but I have no one else to turn to, so here
goes...  I know that moisture-sensitive components require baking prior
to reflow, but how do you bake components that are supplied in tape and
reel?  Can the tape and reels be baked along with the components or do
you have to remove the parts and re-package after baking?
