Ben,

 I am working on a kitting service. Some parts, PCBs and semiconductors for
examples, are something customers want stored in dry storage. Many parts
will come in dry packed and they will remain in dry cabinets. I am just
trying to find what is required for those cabinets. 

 I don't see the need to a baking system as most items are never exposed. A
hot dry storage cabinet might be something customer require if non-dry
stored items need to be brought into a dry state quickly. 

Eventually I hope to have things in a dry vertical carousel but I have not
yet progressed that far.

Bob,

What is your use? If it's for moisture sensitive devices, then you want
something that will stay below 5% (and have a decent recovery time -
J-STD-033 says 1 hr). As to whether this means a 2% cabinet or a 5% cabinet
is appropriate, my guess is that both are, but you'll probably want to take
a close look at the specs and see what the number really means.

Hi,

 

Can anyone make a suggestion for the required level of humidity for a Dry
Cabinet. 

 

I have seen 1%, 2% and 5% cabinets. I notice a small sampling of moisture
indicators have 5% triggers. Does this infer a 2% cabinet is appropriate?

 

I am sure "It Depends" but what are folks using?

 

Thanks,

Bob K.
