7.3. The Moisture Sensitivity Level

The moisture sensitivity level of SIM800C module is 3. The modules should be mounted within 168 hours after

unpacking in the environmental conditions of temperature <30℃ and relative humidity of <60% (RH). It is

necessary to bake the module if the above conditions are not met:

Mandatory bake before use. After bake, it must be reflowed within the time limit

specified on the label.

NOTES:

For product handling, storage, processing, IPC / JEDEC J-STD-033 must be followed.

7.4. Baking Requirements

SIM800C modules are vacuum packaged, and guaranteed for 6 months storage without opening or leakage under

the following conditions: the environment temperature is lower than 40℃, and the air humidity is less than 90%.

If the condition meets one of the following ones shown below, the modules should be baked sufficiently before

re-flow soldering, and the baking condition is shown in below table; otherwise the module will be at the risk of

permanent damage during re-flow soldering.



If the vacuum package is broken or leakage;



If the vacuum package is opened after 6 months since it’s been packed;



If the vacuum package is opened within 6 months but out of its Floor Life at factory ambient≦30℃

/60%RH or as stated.

Note: Care should be taken if that plastic tray is not heat-resistant, the modules should be taken out for

preheating, otherwise the tray may be damaged by high-temperature heating.
