Table 9: Reel Packaging
8.2. Storage
The modules are provided in the vacuum-sealed packaging. MSL of the modules is rated as 3. The
storage requirements are listed below.
1. Recommended storage conditions: The temperature should be 23 ±5 °C and the relative humidity
should be 35
–60 %.
2. The storage life (in vacuum-sealed packaging) is 12 months in Recommended Storage Condition.
3. The floor life of the modules is 168 hours
5
in a plant where the temperature is 23 ±5 °C and relative
humidity is below 60 %. After the vacuum-sealed packaging is removed, the modules must be
processed in reflow soldering or other high-temperature operations within 168 hours. Otherwise, the
modules should be stored in an environment where the relative humidity is less than 10 % (e.g., a
drying cabinet).
4. The modules should be pre-baked to avoid blistering, cracks and inner-layer separation in PCB under
the following circumstances:
⚫
The modules are not stored under Recommended Storage Condition;
⚫
Violation of the third requirement above occurs;
⚫
Vacuum-sealed packaging is broken, or the packaging has been removed for over 24 hours;
⚫
Before module repairing.
5
This floor life is only applicable when the environment conforms to
IPC/JEDEC J-STD-033
. It is recommended to start the
solder reflow process within 24 hours after the package is removed if the temperature and moisture do not conform to, or
are not sure to conform to
IPC/JEDEC J-STD-033
. And do not remove the packages of tremendous modules if they are not
ready for soldering.
