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.
<RECOMMENDABLE CLEANING CONDITIONS>
METHOD CONDITIONS
Cleaning by solvent
Temperature of

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.
<RECOMMENDABLE STORAGE 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).
