hello, I found on label two information about MSL level : MSL-2 - 240C MSL-3 - 260C Does it corresponds to SnPb and Pb-free ?

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

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.

Hi, I'm facing this kind of problem now too. I'm introducing MSL control in the factory I work and the only way to solve this problem is to check every component with moisture barrier bag. I also tried to verify the MSL level in components data shee

Hi John My understanding of your post is that you are asking if anyone has tried to enforce MSL levels or reflow parameters onto the component vendor/manufacturer. Is this your question or am I mis-interpriting it? If that is the case you will not

I am installing MSL (Moisture Sensitivity Level) Controls in the company. I have been trying to contact manufacturers to obtain the MSL level (1-6) for each family of part they produce. Well i havent had a great response as they say refer to the dat

We have seen this same defect. Led's not blinking during test and some tops popping off. Ended up being an msd problem. most of the lite-on components are msl level 4-6. We now bake and track them no problems seen in a while.

Why don't you fix the PCB flatness instead? If that is not the problem, I will check the part warping during the reflow process.If the part is large as you mentioned, it probably warps a lot during reflow. Try to bake the parts in front,based on MSL

Hi Are we talking about a BGA or a resistor. Knowing the type of part would help.
