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

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

Is there any connection with mositure sensitive components and thru-hole devices? All of my research material directs me toward Surface Mount devices.

In the spirit of never assuming anything. Is there a cover that you are not removing?

can you add the datasheet?

Hi, I am facing high fall out of microphone low sensitivity issues. This microphone is soldering thru SMT soldering with low peak temperature profile which peak at 232 DegC to 240 DegC and have skipped X-Ray inspection but still seeing fall out espec

Data sheet allows of 250 DegC peak temperature and we are using below 240 DegC but still seeing high fal out. Manufacturer diagnose as BE charges loss due to heat. Hence, looking for anything extra could be done to minimize this defect. There is no w

Rich: Now that�s a great question!!! You�re corrrect. Primary-side temperature is the driver of the differences in the sensitivity to moisture between SMT and PTH devices that you�re finding. * Primary-side temperature for SMT ~= Secondary-side te

Check the microphone data sheet to find out what the max temperature is...if it's not listed, call the manufacturer. Are you water-washing the board after assembly? Could be water intrusion/entrapment in the microphone. Again, check the data she

Can a bare PCB be ESD-sensitive ? If yes , in what conditions ?
