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

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

Those components can be soldered at both SnPb and Pb Free Reflow process. In case you will submit them to Pb Free Reflow temperature you must treat those components as MSL-3 In case you will submit them to SnPb Reflow temperature, you must treat t

You always follow the MSL label(I attached the table). 1. Use parts 2. Reseal the parts that left. If exparation date is getting close: 1. Use parts 2. Bake the parts left 3. Reseal

As we here are realizing that the list of MSL-3 and higher is much longer than we thought: 1)Component Datasheets do not necessarily state MSL rating. 2)Component manufacturers seem to make it difficult for its users (the folks who buy their produc

I have a double sided PCBA setup. I have MSL components on both assembly sides. When I run Assy Side one I am within the allotted hours remaining on the MSL component. I then wait 40 hours before running 2nd Assy side. By then the hours on the 1s

We currently bake plastic SMT parts in accordance with the IPC guidelines for moisture sensitive parts. Because we have double-sided boards that are subjected to either an aqueous or semi-aqueous cleaning process, we do a 24 hour bake at 125 deg. C

Hi, In our shop we've always baked out PCBs and moisture sensitive parts prior to electronic assembly using a gentle ramp rate of 2 degC/minutes going hot (93degC) and same ramp rate going cold (back to room temp). We're trying to outsource that pro

Also, for MSL 1 and 2, non sealed components, what should be the min/max storing temperatures?
