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
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. 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.

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.
to avoid bending or screwing with great stress of the circuit board.
4.Mounting
finally has bad influence on the product’s reliability.
・The product is not guaranteed for flow soldering.
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.
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
・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.
[MSL0402RGB series]
・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,
the mounter to control the product stabilization. In addition, it is recommended to set ionizer
 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. 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
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
4―4. Mechanical Stress after Mounting
The mechanical stress may damage the LED after Circuit Mounting,
