DRY PACKING
The reel is packed in an anti-humidity bag to protect the
devices from absorbing moisture during transportation and
storage.
FINAL PACKING
The sealed reel is packed into a cardboard box. A secondary
cardboard box is used for shipping purposes.
RECOMMENDED METHOD OF STORAGE
Dry box storage is recommended as soon as the aluminum
bag has been opened to prevent moisture absorption. The
following conditions should be observed, if dry boxes are
not available:
• Storage temperature 10 °C to 30 °C
• Storage humidity ≤ 60 % RH max.
After more than 672 h under these conditions moisture
content will be too high for reflow soldering.
In case of moisture absorption, the devices will recover to
the former condition by drying under the following condition:
192 h at 40 °C + 5 °C / - 0 °C and < 5 % RH (dry air /
nitrogen) or
96 h at 60 °C + 5 °C and < 5 % RH for all device containers
or
24 h at 100 °C + 5 °C not suitable for reel or tubes.
An EIA JEDEC standard JESD22-A112 level 2a label is
included on all dry bags.
Example of JESD22-A112 level 2a label
ESD PRECAUTION
Proper storage and handling procedures should be followed
to prevent ESD damage to the devices especially when they
are removed from the antistatic shielding bag. Electrostatic
sensitive devices warning labels are on the packaging.
