7.4. Baking Requirements

SIM800H&SIM800L 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.
