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.

LEVEL
2a
1. Shelf life in sealed bag 12 months at <40°C and < 90% relative humidity (RH)
2. After this bag is opened devices that will be subjected to infrared reflow,
vapor-phase reflow, or equivalent processing (peak package body temp.
260°C) must be:
a) Mounted within 672 hours at factory condition of < 30°C/60%RH or
b) Stored at <10% RH.
3. Devices require baking before mounting if:
a) Humidity Indicator Card is >10% when read at 23°C + 5°C or
b) 2a or 2b is not met.
4. If baking is required, devices may be baked for:
192 hours at 40°C + 5°C/-0°C and <5%RH (dry air/nitrogen)
or
96 hours at 60±5^oCand <5%RH
For all device containers or
24 hours at 100±5°C
Not suitable for reels or tubes
