lAttention Points In Handling

Visual light emitting diode does not contain reinforcement materials such as glass fillers.

Therefore if sudden thermal and mechanical shock are given, destruction or inferiority of luminous intensity

may occur. Please take care of the handling.

■FIXATION METHOD

1. ATTENTION POINTS

(1) Please do not give excessive heat over storage temperature to resin.

In case that the product has to be heated in oven for the glue fixing of surface mount pats, this LED should

be mounted after the glue fixing.

(2) Please avoid stress to resin at high temperature.

2. TERMINATION PROCESSING

(1) In case of termination processing, please fix the

termination

(2) Processing position, and process the reverse side of

LED body.

If stress is given during processing, It may cause

non-lighting failure.

(3) Please process before soldering.

3. ASSEMBLY ON PC BOARD

(1) In case of soldering on PCB, If the operation is done with stress, it may cause non-lighting failure during

soldering or using.

Please design the through-holes of PCB suitable for lead pins space or lead pins space after formin to avoid

the physical stress on resin.

(2) Using spacer between LED’s body and PCB is recommended.

In case of direct mount on PCB(SLR/SLI-343 series), please take care about clinch of led pins

to avoid the remained stress and solder heat stress.

Enough evaluation is requested before deciding assembly and soldering conditions.

Please consult with us if any problems in the evaluation stage.

4. SOLDERING (Sn-3Ag-0.5Cu)

(1) Please make soldering rapidly under the following temperature and time conditions.

(2) Please avoid stress to LED lamp during soldering.

(3) In case of double peak flow soldering, the temperature gap during 1st and 2nd soldering to be less than 100

degree C.

5. CLEANING

In case of cleaning, some solvents may cause damage of resin or cause non-lighting failure, so please check

the solvent before actual use.

The recommendable cleaning solvent is alcoholic one such as isopropyl alcohol.

METHOD CONDITIONS

Cleaning by solvent

Temperature of

solvent : Max. 45ºC

Immersion time : Max. 3min

Cleaning by solvent Ultrasonic out : Ultrasonic out

Cleaning time : Max. 3min

6. RECOMMENDABLE ROUND PATTERN

Round pattern depends on the material PCB, density and circuit arrangement.

Our recommendation is as follow :

■ATTENTION ON STORAGING

Storage in dry box is most desirable, but if it is not possible, we recommend following conditions.

ARTICLE Temperature Humidity Expiration Date

CONDITIONS 5 to 30ºC Max.60%RH Within 1 year

Poor storage conditions may cause some failure as bellow.

(1) Lead pins may corrode if it is stored in the environment of high temperature and humidity and lead to defective

soldering.

(2) In case of soldering after LED’s body absorb moisture highly, destruction or inferiority of luminous intensity

may occur.

■APPLICATION METHOD

1. Precaution for Drive System and Off Mode

• Design the circuit without the electric load exceeding the ABSOLUTE MAXIMUM RATING that applies on the

products.

• If drive by constant voltage, it may cause current deviation of the LED and result in deviation of luminous

intensity, so we recommend to drive by constant current. (Deviation of VF Value will cause deviation of current

in LED.)

• Furthermore, for off mode, please do not apply voltage neither forward nor reverse. Especially, for the products

with the Ag-paste used in the die bonding, there’s high possibility to cause electro migration and result in

function failure.

2. Operation Life Span

There’s possibility for intensity of light drop according to working conditions and environments (applied current,

surrounding temperature and humidity, corrosive gases ), please call our Sales staffs for inquiries about the

concerned application below.

(1) Longtime intensity of light life

(2) On mode all the time

3. Usage

The Product is LED. We are not responsible for the usage as the diode such as Protection Chip, Rectifier,

Switching and so on.

■OTHERS

1. Surrounding Gas

Notice that if it is stored under the condition of acid gas (chlorine gas, sulfured gas) or alkali gas (ammonia),

it may result in low soldering ability (caused by the change in quality of the plating surface ) or optical 　

characteristics changes (light intensity, chrominance) and change in quality of die bonding (Ag-paste) 　

aterials.

All of the above will cause function failure of the products.

Therefore, please pay attention to the storage environment for mounted product (concern the generated gas of

the surrounding parts of the products and the atmospheric environment).

2. Electrostatic Damage

The product is part of semiconductor and electrostatic sensitive, there’s high possibility to be damaged by the

electrostatic discharge.

Please take appropriate measures to avoid the static electricity from human body and earthing setting of

production equipment. The resistance values of electrostatic discharge (actual values) are different varies with

products, therefore, please call our Sales staffs for inquiries.

3. Electromagnetic Wave

Please concern the influence on LED in case of application with strong electromagnetic wave such as IH

(Induction heating).
