If these are moisture sensitive they are required to be shipped in a moisture barrier bag and labeled as moisture sensitive. Depending on which moisture sensitivity level (MSL) the components have, floor life can range from unlimited to a mandatory

you should go for a dry box it would prevent the sensitive component. Though Moisture sensitive devices are packaged in a moisture barrier antistatic bag with a desiccant and a moisture indicator card which is sealed which could help you.

Has anyone experienced more moisture adsorbing into the moisture sensitive part than the beads in the approved desiccant bag in the MBB. The reason for this is a concern is by having the part adsorb more moisture, the HIC card can give a false readi

I agree with Graham Cooper. -033 does not explicitly allow for the use of this type of bag. We had the same question asked here a few months ago and my answer was the same. While it's possible/likely that the bag material meets the WVTR spec, my c
