Cautions

1、Package

When moisture is absorbed into the package it may vaporize and expand during soldering. There is a

possibility that this can cause exfoliation of the contacts and damage to the optical characteristics of the LEDs.

So the moisture proof package is used to keep moisture to a minimum in the package.

2、Storage

Before opening the package: The LEDs should be kept at 5~30°C and 60%RH or less. The LEDs should

be used within a year.

After opening the package: The LED must be used within 24 hours, else should be kept at 5~30℃ and

30% RH or less. The LEDs should be used within 7days after opening the package. If unused LEDs remain,

they should be stored in moisture proof packages, recommended to return the LEDs to the original moisture

proof bag and to reseal the moisture proof bag again.

If the LEDs have exceeded the storage time, baking treatment should be performed more than 24 hours at

60 ± 5°C.

3、Soldering Iron

Each terminal is to the tip of soldering iron temperature less than 300℃ for 3 seconds within once in less

than the soldering iron capacity 25 W.Leave two seconds and more internals, and do soldering of each

terminal. Be careful because the damage of the product is often started at the time of the hand solder.

4、Repairing

Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable, a

double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the

characteristics of the LEDs will or will not be damaged by repairing.

5、The LED electrode sections are comprised of a gold plated. The gold surface may be affected by

environments which contain corrosive gases and so on. Please avoid conditions which may cause the LED to

corrode or discolor. This corrosion or discoloration may cause difficulty during soldering operations. It is

recommended that the User use the LEDs as soon as possible.

6、Please avoid rapid transitions in ambient temperature, especially in high humidity environments where

condensation can occur.
