We are baking the moisture out of our ic chips. They are on tape and reel. Can we bake them on tape and reel or do we have to put them in trays?

IPC-1601 covers PWB bake-out, methods for determining optimum bake time and temperature, caveats for certain PWB plating finishes, etc. IPC-1601 is to bare boards as J-STD-033 is to components

Yes, that point remains unchanged. Just a general comment that there have been updates. e.g. re: desiccant re-use, certain devices no longer requiring bake-out, or bake times have been adjusted, and more.

I should explain that this bake out was performed after population. The solder paste slumped terribly after this bake out. However, after the back out and after reflow, no bridging.

Well, it's hard to say what it started out as, a smear, splash or ball cause the solder formation on the finger after reflow is spread out ya know. I looked at an archive for possible causes and one was printer operators with paste on their fingers.

1) I'm not familiar with the acronym CAF. Could you spell that one out for me? 2)Why do you feel they need to be baked? Are they in a high humidity enviornment? the only time we bake is when we are dealing with moisture sensitive components. Do you b

Ooooo, much better. Tough to say, because of all the variables [ie, different materials, moisture level, temperature, etc]. Plastic encapsulated devices, especially IC, absorb water from the air, which is violently released during soldering. Typica

You should be baking above 100C/212F to ensure that you're driving moisture out of the board. Four hours at 225F is usually enough to dry out most multilayer PWBs.
