Moisture Sensitivity Level (MSL)

SIM7100 is qualified to Moisture Sensitivity Level (MSL) 5 in accordance with JEDEC J-STD-033. After
the prescribed time limit exceeded, users should bake modules for 192 hours in drying equipment (<5%
RH) at 40° C +5° C/-0° C, or 72 hours at 85° C +5° C/-5° C. Note that plastic tray is not heat-resistant,
users must not use the tray to bake at 85° C or the tray may be damaged.
