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 hours 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 hours at 40 °C + 5 °C/- 0 °C and < 5 % RH

(dry air/nitrogen) or

96 hours at 60 °C + 5 °C and < 5 % RH for all device

containers or

24 hours 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.

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.

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:

or

For all device containers

or

24 hours at 100±5°C

Not suitable for reels or tubes
