According to J-STD-033B, 3.1 Requirements: The levels are determined per J-STD-020 and/or per JESD22-A113 plus reliability testing. Look here: http://www.jedec.org/download/search/jstd020c.pdf

Hi Nicolas, For level 4 and above you can NOT stop the floor life when the items are exposed for more than 8 hrs even if you store them in a dry cabinet or seal them back in MBB. For Level 3 and below you can stop/ pause the floor life whenever y

Hi Christopher, To my knowledge, heat seal along will not provide you the desire condition. Currently, we're using vacuum sealer to reseal all MSD restock items. If you have variety of package and constantly need to reseal the MSD parts, I'd like to

Another important element to consider is the impact of ambient temperature and humidity on Moisture Sensitive Components. The majority of plastic encapsulated ICs are classified as moisture-sensitive devices (MSD). This means that they are qualifie

What is the MS-level and floor life of the critical components (should be written on the MSD-bag)? What is Your climate condition in the production area (%RH, temp.)? Are you doing this inspection on every board or is it enough to do it on the first

Hi Gavin, Depends on what MSD class, but in general for the more sensitive parts if they've been opened & not used within the time limit it's rebake, add dessicant & seal. Our distribution side splits them down into more manageable/production size

Hi! to all, Here in our company, we sometimes received BGAs and ICs that were packed poorly(not sealed), and no MSL level written to it from our suppliers, now we subject the material for baking before using it. We use J-STD-033B table 4-1 as our cr

A reputable supplier will identify the level CLEARLY on the packaging and in the datasheet as well. If they are KNOWN to be MSDs, I'd be suspicious if they aren't marked. Or, they may not be MSDs. I don't think it's required to ID them as "M1" if n

Wave Solder temperature should not cause problem to MSDs. Just in case on PBA there are very critical MSLs (ie. 5 or 5a, 6 (?!?) try to detect what is the max temperature on such MSD bodies and how long they stay under such temperature. But it schoul

We have used some sealed steel cabinets and a nitrogen generator (Balston 75-79 model) for about a dozen years with no issues at all. Humidity levels average 1% - 5%. We also just bought a couple of XDry (Totech) desiccant cabinets (XD2-1104-02) for
