[Data Sheet]
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
・Baking
Bake the product in case of below:
①The expiration date is passed.
②The color of indicator (silica gel) turned from blue to colorless or from green to pink.
・Baking Conditions
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
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
２－２．Derating
The Derating Characteristics are based on the lifetime of luminous intensity and assumption
of degradation & color change of sealing resin or reflector. About its reliability,
２－３．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
①Longtime intensity of light life
②On mode all the time
２－４．Applied Stress on Product
No resin hardening agent such as filler is used in the sealing resin of the product.
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.

so please try not to apply stress on it.
・Recommend bake once.
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,
in function failure.
please evaluate its using conditions and environment and use it after confirmed there is no problem.

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
Therefore, please pay attention to the storage environment for mounted product (concern the
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
Applications with strong electromagnetic wave such as, IH cooker, will influence the reliability of LED,
please refrain from it. Otherwise, there is no guarantee for product quality.

so please pay attention to the touch on product.
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.
※The product has adopted the electrode structure that it should solder
with back electrode of the product.
Thus, please be informed that the shape of electrode pin of
solder fillet formation is not guaranteed.
The through hole on electrode surface is for conduction of front
and rear electrodes but not for formation of solder fillet.
４―４. Mechanical Stress after Mounting
The mechanical stress may damage the LED after Circuit Mounting,
４－５．Soldering Pattern for Recommendation
The stress like bending stress of circuit board dividing after mounting, may cause LED package crack
・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.
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 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
・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.
expansion and moisture absorption at humidity will cause heat stress during soldering process and
shift (within 3℃/sec. of temperature gradient) during the flow soldering of surrounding parts.
・Please set appropriate reflow temperature based on our product usage conditions and specification.
[SML-012x/013x series]
to avoid bending or screwing with great stress of the circuit board.
・Do not expose the product in the environment of high temperature (over 100℃) or rapid temperature
４．Mounting
４－１. Soldering
・No resin hardening agent such as filler is used in the sealing resin of the product. Therefore, resin
