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

aluminium 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. Electro-static sensitive devices warning

labels are on the packaging.
