TCS3472 − Soldering & Storage Information

Storage Information

Moisture Sensitivity

Optical characteristics of the device can be adversely affected

during the soldering process by the release and vaporization of

moisture that has been previously absorbed into the package.

To ensure the package contains the smallest amount of

absorbed moisture possible, each device is dry-baked prior to

being packed for shipping. Devices are packed in a sealed

aluminized envelope called a moisture barrier bag with silica

gel to protect them from ambient moisture during shipping,

handling, and storage before use.

The Moisture Barrier Bags should be stored under the following

conditions:

• Temperature Range < 40°C

• Relative Humidity < 90%

• Total Time - No longer than 12 months from the date code

on the aluminized envelope if unopened.

Rebaking of the reel will be required if the devices have been

stored unopened for more than 12 months and the Humidity

Indicator Card shows the parts to be out of the allowable

moisture region.

Opened reels should be used within 168 hours if exposed to the

following conditions:

• Temperature Range < 30°C

• Relative Humidity < 60%

If rebaking is required, it should be done at 50°C for 12 hours.

The FN package has been assigned a moisture sensitivity level

of MSL 3.
