13. CAUTIONS:

(1)Storage

‧Before opening the package :

The LEDs should be kept at 30℃ or less and 30%RH~85%RH. The LEDs should be

used within a year. When storing the LEDs, moisture proof packaging with desiccant

(Silica gel)is recommended.

‧After opening the package :

The LEDs should be kept at 30℃ or less and 30%RH~70%RH.The LEDs should be

soldered within 168hours (7days) after opening the package. If unused LEDs remain,

they should be stored in moisture proof packages, such as sealed containers with

packages of moisture desiccant (Silica ge1), or reseal the moisture proof bag again.

If the moisture desiccant (Silica ge1)has faded away or the LEDs have exceeded the

storage time, baking treatment should be performed using the fo1lowing conditions.

Baking treatment: more than 24 hours at 65℃.

Please avoid conditions which may cause the LED to corrode, tarnish or disco1or. This

corrosion or discoloration might lower solderability or might effect on optical

characteristics.-Please avoid rapid transitions in ambient temperature, especially in high

humidity environments where condensation can occur.

‧Moisture Proof package

When moisture is absorbed into the SMT 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. For this reason, the moisture proof package is

used to keep moisture to a minimum in the package. A package of a moisture desiccant

(silica gel)is inserted into the moisture proof bag-The silica gel changes its color from

blue to pink as it absorbs moisture.

(2)Static Electricity

‧Static electricity or surge voltage damages the LEDs. It is recommended that a wrist band

or an anti-electrostatic glove and shoe be used when handling the LEDs.

‧All devices, equipment and machinery must be properly grounded. It is recommended that

measures be taken against surge voltage to the equipment that mounts the LEDs.

‧when inspecting the final products in which LEDs were assembled, it is recommended to

check whether the assembled LEDs are damaged by static electricity or not. It is easy to

End static-damaged LEDs by a light-on test or a V_Ftest at a lower current (below l mA).

‧Damaged LEDs will show some unusual characteristics such as the leak current

remarkably increases, the forward voltage becomes lower, or the LEDs do not light at the

low current. (Criteria : V_F>2.0V at I_F=0.5mA.)

(3)Heat Generation

‧Please consider the heat generation of the LED when making the system design that it’s

very importance. The coefficient of temperature increase per input electric power is

effected by the thermal resistance of the circuit board and density of LED placement on

the board, and other components. It is necessary to avoid intense heat generation and

operate within the maximum ratings given in this specification.

‧The operating current should be decided after considering the ambient maximum

temperature of LEDs.

(4)Others

‧Care must be taken to ensure that the reverse voltage will not exceed the absolute

maximum rating when using the LEDs with matrix drive.

‧The LED light output is strong enough to injure human eyes. Precautions must be taken to

prevent looking directly for more than a few seconds. Flashing lights have been known to

cause discomfort in people; you can prevent this by taking precautions during use. Also,

people should be cautious when using equipment that has had LEDs incorporated into it.
