MSL Rating

The reliability of electronic components is validated using Moisture Sensitivity Level (MSL) tests because board mounting processes, especially solder reflow (for Surface Mount Devices - SMD), involve a high moisture vapor pressure inside plastic packages and high temperatures - as high as 260ºC for lead free reflow processes.

Knowing the part MSL classification level enables proper packaging, storage, and handling of SMD to prevent potential damage as a result of moisture induced stress during soldering or repair operations.
