8.1 Storage
SLM770A modules are shipped in vacuum sealed bags. The storage of modules is subject to the
following conditions:
1. When the environment temperature is below 40℃ and the air humidity is less than 90%, the module
can be stored in a vacuum sealed bag for 12 months.
2. After the vacuum sealing bag is opened, the module can directly carry out reflow welding or other
high-temperature processes if the following conditions are met:
⚫ The air humidity for module storage is lower than 10%;
⚫ The ambient temperature of the module is lower than 30℃, the air humidity is lower than 60%, and
the factory completes the placement within 72 hours.
3. If the module is in the following conditions, it needs to be baked before placement:
⚫ When the environment temperature is 23℃ (±5 ℃ fluctuations are allowed), the humidity
displayed by the humidity indicator card is greater than 10%;
⚫ After the vacuum-sealed bag is opened, the ambient temperature of the module is lower than 30℃
and the air humidity is lower than 60%, but the factory fails to complete the placement within 168
hours;
⚫ After the vacuum-sealed bag is opened, the air humidity for module storage is greater than 10%.
4. If the module needs to be baked, bake it for 8 hours at 125℃ (±5 ℃ fluctuations are allowed).
Note: The package of the module cannot withstand such high temperature, please remove the package
of the module before the module is baked.
