・Bake products in reel.
・Reel and embossed tape are easy to be deformed when baking,
Remark
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．About Derating
It is considered that derating characteristics will not result in LED chip's electrical destruction.
Even within the derating, the reliability and luminous life can be affected depending on operating
conditions and ambient environment. So we would be appreciate it if you can confirm with your
application again.
２－３．About product life
Depending on operating conditions and environment(applied current, ambient temperature and
humidity, corrosive gas), decreasing of luminosity and change of chromaticity may occur even
within the specification conditions.
Please contact our sales office if you use it for the following applications.
①It requires long luminosity life
②It is always lit
２－４．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.
２－５．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 cause die bonding (Ag-paste) materials. All of the above will 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. Especially, InGaN type LEDs have lower resistance
value of electrostatic discharge and it is recommended to introduce the ESD protection circuit.
The resistance values of electrostatic discharge (actual values) vary with products, therefore,
please call our Sales staffs for inquiries.
３－３． Electromagnetic Wave
Applications with strong electromagnetic wave such as, IH cooker, will influence the reliability of LED,
therefore please evaluate before using it.

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 guaranteed for flow soldering.
・Do not expose the product in the environment of high temperature (over 100℃) or rapid temperature
shift (within 3℃/sec. of temperature gradient) during the flow soldering of surrounding parts.
In case of carrying out flow soldering of surrounding parts without recommended conditions, please
contact us for inquiries.
・Please set appropriate reflow temperature based on our product usage conditions and specification.
・The max for reflowing is 2 times, please finish the second reflow 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.
・For our product that has no solder resist, because of its solder amount and soldering conditions,
one of its specific characteristics is that solder will penetrate into LED. Thus, there's high possibility
that will influence its reliability.Therefore, please be informed, concerning it before using it.
４－２. Automatic Mounting
４-２-１. Suction nozzle
Excessive load may cause damage inside the LED product, so select an optimal suction nozzle
according to the material and shape of the LED product.
４-２-２. Mini Package (Smaller than 1608 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.
Stress strength according to
he mounting position:
A＞B＞C＞D
４―４. Mechanical Stress after Mounting
The mechanical stress may damage the LED after Circuit Mounting,
so please pay attention to the touch on product.
４－５．Soldering Pattern for Recommendation
We recommend the soldering pattern that shows on the right.
It will be different according to mounting situation of circuit board,
therefore, please concern before designing.
