Packaging

This LED device is packed in an aluminum envelope with a silica gel and a moisture indicator to avoid moisture

absorption. The optical characteristics of the device may be affected by exposure to moisture in the air before

soldering and the device should therefore be stored under the following conditions:

1. This moisture proof bag may be stored unopened within 12 months at the following conditions.

Temperature: 5

°C to 30°C

Humidity: 90% (max)

2. After opening the moisture proof bag, the device should be assembled within 4weeks in an environment of 5°C

to 30°C/60% RH or below.

3. If upon opening, the moisture indicator card shows humidity 30% or above (Color of indication changes to

pink) or the expiration date has passed, the device should be baked in taping with reel.

After baking, use the baked device within 72 hours, but perform baking only once.

Baking conditions: 60

±5°C, for 24 to 48 hours.

Expiration date: 12 months from sealing date, which is imprinted on the label affixed.

4. Repeated baking can cause the peeling strength of the taping to change, then leads to trouble in mounting.

5. If the packing material of laminate would be broken, the hermeticity would deteriorate. Therefore, do not

throw or drop the packed devices.

Mounting Method

Soldering

• Reflow soldering (example)

• The product is evaluated using above reflow soldering conditions. No additional test is performed exceed the

condition (i.e. the condition more than max(*) values) as a evaluation. Please perform reflow soldering under

the above conditions.

• Please perform the first reflow soldering with reference to the above temperature profile and within 4weeks of

opening the package.

• Second reflow soldering

In case of second reflow soldering should be performed within 168 h of the first reflow under the above

conditions.

Storage conditions before the second reflow soldering: 30

°C, 60% RH (max)

• Make any necessary soldering corrections manually.
