Hi Scott!

This can be kinda' tricky...3M makes carrier tape that can withstand high
temperatures but also says that the coverr tape should be of a PSA (Pressure
Sensitive Adhesive) type. I have heard of baking tape and reel components
that have a heat-seal type of cover tape, and having the components sealed in
by the tape so securely that they weren't able to be used in the feeder...the
cover tape would just keep breaking...

Harris Semiconductor has a *.PDF at:

http://rel.semi.harris.com/docs/rel/tb363_2.pdf

That says to bake moisture sensitive tape and reeled components at 40 C. +5
-0 C. at lower than 5% reletive humidity for at least 192 hours...that's
8-days!

I've never baked tape and reel components, so I can't tell you anything first
hand. You may want to consider outsourcing this. There are tape and reel
companies that will take them out of their current tape, bake them, and then
re-tape them and seal them inside of a moisture proof vacuum sealed bag with
dessicant inside.
