MSL rating is not tied to a specific package type/size. I have seen 2 components (ICs) have the same physical package but one was MSL-3 while the other was MSL-5. From my experience, while component manufacturers are not consistent as to where they

11,000 parts? Easy life. We have 66,000 lines in stock & about 500,000 on the system. We've added extra fields on the database for every part number with ROHS status, MSL, PBT, & end termination info added. We've also had to create duplicate part

Hi, I am trying to write SOP about the baking requirement of some CSP and uBGA components, the label on the packing said its usable within 72 hours and follow the MSL 4 condition, what does the MSL means? is it Material Safety Level? Has anything to

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

Am I reading your post correctly? You will print PCBs and not populate them until up to 24 hours later? And you can assemble level 3 components at 30C and 90% humidity, you just have to pro-rate the exposure time. (I don't recommend having those con

could also be a component issue...delamination/popcorning of the component....what is the MSL level?

We are talking about an IC in a TO263 package.

If an electronic component with a MSL rating of 1 is exposed to an moist environment greater than the 85% relative humidity to the point where the packaging is wet, what is the risk level of using the device in a lead-free soldering reflow process?
