lPrecaution (Surface Mount Device)
1.Storage
If the product is heated during the reflow under the condition of hygroscopic state, it may vaporize and expand
which will influence the performance of the product. Therefore, the package is waterproof. Please use the
product following the conditions:
• Using Conditions

Remark
Within 1 year
Storage with waterproof package
from Receiving
Within 168h
Please storing in the airtight container with
our desiccant (silica gel)
• Baking
Bake the product in case of below:
1 The expiration date is passed.
2 The color of indicator (silica gel) turned from blue to colorless or from green to pink.
(Even if the product is within the expiration date.)
• Baking Conditions
Temperature
60±3ºC
Remark
Time
12 to 24h
Humidity
Below 20%RH
• Bake products in reel.
• Reel and embossed tape are easy to be deformed when baking, so please try not to
apply stress on it.
• Recommend bake once.
2.Application Methods
2-1. 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.
2-2. 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
2-3.Applied Stress on Product
The top of the LED is very soft, which the silicon resin is used as sealing resin. Therefore, please pay attention
to the overstress on it which may influence its reliability.
2-4.Usage
The Product is LED. We are not responsible for the usage as the diode such as Protection Chip, Rectifier,
Switching and so on.

3. Others
3-1. 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) materials.
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).
3-2. 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 of production equipment. The resistance values of electrostatic discharge (actual values) vary with
products, therefore, please call our Sales staffs for inquiries.
3-3. Electromagnetic Wave
Please concern the influence on LED in case of application with strong electromagnetic wave such as IH
(Induction heating).
4.Mounting
4-1. Soldering
• No resin hardening agent such as filler is used in the sealing resin of the product. Therefore, resin expansion
and moisture absorption at humidity will cause heat stress during soldering process and finally has bad
influence on the product’s reliability.
• The product is not for flow soldering.
• Do not expose the product in the environment of high temperature (over 100ºC) or rapid temperature shift
(within 3ºC of temperature gradient) during the flow soldering of surrounding parts.
• Please set appropriate reflow temperature based on our product usage conditions and specification.
• The max for reflowing is 2 times, please finish the second flow soldering and flow soldering with other parts
within the usage limitation after open the moistureproof package.
• Compare with N2 reflow, during air reflow, because of the heat and surrounding conditions, it may cause the
discoloration of the resin.
4-2. Automatic Mounting
4-2-1.Silicon Resin Sealing Product
The sealing resin of LED is very soft, so please select adsorption nozzle that would not apply stress directly
on the sealing section.
4-2-2.Mini Package (Smaller than 1006 size)
Vibration may result in low mounting rate since it will cause the static electricity of product and adhere to top
cover tape. Therefore, the magnet should be set on parts feeder cassette of the mounter to control the product
stabilization. In addition, it is recommended to set ionizer to prevent electrostatic charge.
4-3. Mounting Location
The stress like bending stress of circuit board dividing after mounting, may cause LED package crack or
damage of LED internal junction, therefore, please concern the mounting direction and position to avoid bending
or screwing with great stress of the circuit board.
