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.

This has been a problem with new components coming directly from vacuum sealed desiccant packed moisture barrier bags with moisture level cards. We have also baked all boards prior to the BGA rework to ensure no moisture issues were addressed.

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

Not a Vacuum Person and yes, the moisture level reads good, but the part has too much moisture.

hi, lately I have problem with smd leds.After reflow 2-4% of leds are broken.I think , that reason is bad storage of components, because in our stock the tape with leds have not Moisture Barrier Bags.My question is ,how you storage components, which

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

Hegeman: So you receive these boards in seal moisture barrier bags, store them in a controlled environment, and use them as needed; what is your goal in baking these poor babies?

Polymide is like a sponge and absorbs moisture much faster than rigid substrates. Pre-bake your substrate for 2-4 hours at 125C and perform your soldering within 1 shift thereafter or seal in moisture barrier bags.
