moisture sensitivity level (MSL)

The Moisture Sensitivity Level (MSL) is a factor that refers to the humidity and the time period to which semiconductor components or chips

may be exposed during storage, transport and assembly. The MSL value is a type of classification used to make a statement about the moisture exposure of electronic components and encapsulated integrated circuits


MSL values for the humidity limits of components

MSL values for the humidity limits of components

The value itself is given as a numerical value together with the abbreviation MSL, for example MSL-2. There are six numerical MSL values which indicate the exposure duration, the room temperature and the room humidity to which the electronic assemblies may be exposed.
