Has anyone been using low humidity dry cabinets for storing moisture sensitive devices? Any suggestion on the right equipment vendor? Thank you.

We have a "McDry" cabinet. It works well.

We use Super Dry. The oldest ones are about 5 years old and we haven't had a problem.

If you're looking for something for less than $5-10k, you should consider setting up a point-of-use air drying system. If you can supply fairly dry air from a house system to the point of use dryer, you can acheive humidty levels below 2% easily. W

Dave, I would only agree with you when you talk about low residue (water based) fluxes. In low residue (alcohol based) fluxes you can use non water soluble acids, so in the event you still have flux residues on the board water has no effect on them.

Patrick: The flux was OA, but you can get the same result with low residue flux.

Patrick I can only agree with you about low residue (alcohol based) fluxes, providing you apply the amount specified by the supplier. Amounts in excess of the specified amount can have harmful effects.

Dave, A low residue/No residue flux does exist that when an excessive amount of flux is applied it would only create a cosmetic problem not a reliability issue. The active ingredients are neutralized by the heat applied in the soldering machine and
