Note: For more details about secondary SMT, please refer to the document [21].
6.4 Moisture Sensitivity Level (MSL)
Module is qualified to Moisture Sensitivity Level (MSL) 3 in accordance with JEDEC J-STD-033.
If the prescribed time limit is exceeded, users should bake modules for 192 hours in drying
equipment (<5% RH) at 40+5/-0°C, or 72 hours at 85+5/-5°C. Note that plastic tray is not
heat-resistant, and only can be baked at 45° C.
