SOLDERING
• Recommended Hand Soldering Condition
Temperature
380°C Max
Soldering Time
5sec Max
* Hand soldering must not be performed more than once.
* This LED uses a silicone resin for the encapsulating resin frame or resin area; the silicone resin is soft. If excess pressure is applied
to the silicone resin, it may cause the resin to be damaged, chipped, cracked and/or deformed. If the encapsulating resin frame
and/or resin area are damaged, chipped, cracked and/or deformed, it may cause the wire to break causing a catastrophic failure
(i.e. the LED not to illuminate) and/or reliability issues (e.g. the LED to corrode and/or to become dimmer, the color directivity to
change, etc.).
* Repairing should not be done after the LEDs have been soldered. It should be confirmed beforehand whether the characteristics
of the LEDs will or will not be damaged by repairing.
* When soldering, do not apply stress to the LED while the LED is hot.
* When using an automatic pick-and-place machine, choose an appropriate nozzle for this LED. Using a pick-and-place nozzle with
a smaller diameter than the size of the LED's emitting surface will cause damage to the emitting surface causing a catastrophic
failure (i.e. the LED not to illuminate).
* When flux is used, it should be a halogen free flux. Ensure that the manufacturing process is not designed in a manner where the
flux will come in contact with the LEDs.
* During and/or after soldering an electric wire to the electrode, ensure that tension is not applied to the electric wire. This may
cause the electrode to be damaged and/or reduce the adhesive strength of the electrode to the package.
* If soldering is used to join electric wires to the electrodes, the adhesive strength of the electrode to the package may be reduced
depending on the substances that are found in the solder paste and/or the type of the wire cover that is used. Ensure that there
are no issues with the materials that will be used in the chosen application prior to use.

To store any remaining unused LEDs, use a hermetically sealed container with silica gel desiccants. Nichia recommends placing
them back to the original moisture-proof bag and reseal it.
● This LED has gold-plated electrodes. If the LEDs are exposed to a corrosive environment, it may cause the plated surface to
tarnish causing issues. Ensure that when storing LEDs, a hermetically sealed container is used. Nichia recommends placing them
back to the original moisture-proof bag and reseal it.
● To prevent substances/gases from affecting the plated surface, ensure that the parts/materials used with the LEDs in the same
assembly/system do not contain sulfur (e.g. gasket/seal, adhesive, etc.). If the plating is contaminated, it may cause issues (e.g.
electric connection failures). If a gasket/seal is used, silicone rubber gaskets/seals are recommended; ensure that this use of
silicone does not result in issues (e.g. electrical connection failures) caused by low molecular weight volatile siloxane.
● To avoid condensation, the LEDs must not be stored in areas where temperature and humidity fluctuate greatly.
● Do not store the LEDs in a dusty environment.
● Do not expose the LEDs to direct sunlight and/or an environment over a long period of time where the temperature is higher than
normal room temperature.
(2) Directions for Use
● The circuit must be designed to ensure that the Absolute Maximum Ratings are not exceeded for each LED. The LEDs should be
operated at a constant current per LED. In the case of operating at a constant voltage, Circuit B is recommended. If Circuit A is
used, it may cause the currents flowing through the LEDs to vary due to the variation in the forward voltage characteristics of the
LEDs on the circuit.

● This LED is designed to be operated at a forward current. Ensure that no voltage is applied to the LED in the forward/reverse
direction while the LED is off. If the LEDs are used in an environment where reverse voltages are applied to the LED continuously,
it may cause electrochemical migration to occur causing the LED to be damaged. When not in use for a long period of time, the
system’s power should be turned off to ensure that there are no issues/damage.
● When using the LEDs with a dimmer, the color may vary depending on the current through the LED; it is recommended to operate
the LED with pulse width modulation (PWM) to minimize this issue.
● To stabilize the LED characteristics while in use, Nichia recommends that the LEDs are operated at currents ≥ 10% of the sorting
current.
● Ensure that transient excessive voltages (e.g. lighting surge) are not applied to the LEDs.
● If the LEDs are used for outdoor applications, ensure that necessary measures are taken (e.g. protecting the LEDs from water/salt
damage and high humidity).
(3) Handling Precautions
● Do not handle the LEDs with bare hands:
- this may contaminate the LED surface and have an effect on the optical characteristics,
- this may cause the LED to deform and/or the wire to break causing a catastrophic failure (i.e. the LED not to illuminate).
● Ensure that when handling the LEDs with tweezers, excessive force is not applied to the LED. Otherwise, it may cause damage to
the resin (e.g. cut, scratch, chip, crack, delamination and deformation) and the wire to break causing a catastrophic failure (i.e.
the LED not to illuminate).
● Dropping may cause damage to the LED (e.g. deformation).
● Do not stack the LEDs. Otherwise, it may cause damage to the resin (e.g. cut, scratch, chip, crack, delamination and deformation)
and the wire to break causing a catastrophic failure (i.e. the LED not to illuminate).

(4) Design Consideration
● Volatile organic compounds that have been released from materials present around the LEDs (e.g. housing, gasket/seal, adhesive,
secondary lens, lens cover, etc.) may penetrate the LED lens and/or encapsulating resin. If the LEDs are being used in a
hermetically sealed environment, these volatile compounds can discolor after being exposed to heat and/or photon energy and
it may greatly reduce the LED light output and/or color shift. In this case, ventilating the environment may improve the reduction
in light output and/or color shift. Perform a light-up test of the chosen application for optical evaluation to ensure that there are
no issues, especially if the LEDs are planned to be used in a hermetically sealed environment.
● This LED uses a ceramic material for the substrate; if the LED is attached to a housing in an inappropriate manner (e.g. uneven
application of force to the ceramic substrate, unstable holding, etc.), it may cause the substrate to crack. Nichia recommends
using a specially designed holder to attach the LEDs to a housing.
● If the LEDs are attached to a housing without a thermal interface material (e.g. thermal film, thermal grease, etc.), it may cause
the heat dissipation to decrease. Nichia recommends using a thermal interface material between the LED and housing.
(5) Electrostatic Discharge (ESD)
● This LED is sensitive to transient excessive voltages (e.g. ESD, lightning surge). If this excessive voltage occurs in the circuit, it
may cause the LED to be damaged causing issues (e.g. the LED to become dimmer or not to illuminate [i.e. catastrophic failure]).
Ensure that when handling the LEDs, necessary measures are taken to protect them from an ESD discharge. The following
examples are recommended measures to eliminate the charge:
- Grounded wrist strap, ESD footwear, clothes, and floors
- Grounded workstation equipment and tools
- ESD table/shelf mat made of conductive materials
● Ensure that all necessary measures are taken to prevent the LEDs from being exposed to transient excessive voltages (e.g. ESD,
lightning surge):
- tools (e.g. soldering irons), jigs, and machines that are used are properly grounded
- appropriate ESD materials/equipment are used in the work area
- the system/assembly is designed to provide ESD protection for the LEDs.
● If the tool/equipment used is an insulator (e.g. glass cover, plastic, etc.), ensure that necessary measures have been taken to
protect the LED from transient excessive voltages (e.g. ESD). The following examples are recommended measures to eliminate
the charge:
- Dissipating static charge with conductive materials
- Preventing charge generation with moisture
- Neutralizing the charge with ionizers

(6) Thermal Management
● When using this product, ensure that proper thermal management is provided and the die temperature does not exceed the
maximum Junction Temperature (TJ). The temperature at the LED junction, once the saturation temperature has been reached,
can be calculated using the following equation:
TJ=TC+RθJC・W
*TJ=LED Junction Temperature: °C
TC=Case Temperature: °C
RθJC=Thermal Resistance from Junction to TC Measurement Point: °C/W
W=Input Power(IF×VF): W
TC Measurement Point
● RθJC may change depending on the properties for both the thermal interface material used (e.g. film, gel sheet, paste, or glue) and
the heat sink/housing and the surface state of those materials. Ensure that when mounting the LEDs on to the heat sink/housing,
the following points are considered:
- A thermal interface material with a low thermal resistance should be used for the interface between the LED and heat
sink/housing.
- The surface of the heat sink used with the LEDs must not have any small recesses, cavities, or holes; if necessary, the surface
must be leveled before mounting the LEDs.
- If a holder and/or thermal interface material are used, ensure that these materials are properly used and the heat is
effectively dissipated.
During use if the thermal interface material deteriorates due to heat and the dimensions change and/or the properties degrade,
it may cause these materials not to dissipate the heat properly; this may cause the LED to be damaged. Ensure that reliability
verification is performed for the chosen application.
● When measuring the temperatures of LEDs for the thermal management design, a non-contact temperature measuring
instrument (e.g. thermal imaging camera) should be used.
● Refer to the relevant application notes for detailed information (e.g. how to handle the COB LEDs, the effect of
adhesion strength between the COB and the housing, thermal design considerations, etc.). To access the
application notes, go to the Technical Suggestions And Recommendations section of Nichia’s website.
(7) Cleaning
● Do not clean the LEDs with water, benzine and/or thinner.
● To clean the LEDs, use isopropyl alcohol (IPA). If another solvent is used, it may cause the LED package/resin to be damaged
causing issues; ensure that sufficient verification is performed prior to use. Additionally, ensure that the solvent being used does
not cause any other issues (e.g. CFC-based solvents are heavily regulated).
● If an LED is contaminated (e.g. dust/dirt), use a cloth soaked with isopropyl alcohol (IPA). Ensure that the cloth is firmly squeezed
before wiping the LED.
● Do not clean the LEDs with an ultrasonic cleaner. If cleaning must be done, ensure that sufficient verification is performed by using
a finished assembly with LEDs to determine cleaning conditions (e.g. ultrasonic power, LED position on the PCB assembly) that do
not cause an issue.

(8) Eye Safety
● There may be two important international specifications that should be noted for safe use of the LEDs: IEC 62471:2006
Photobiological safety of lamps and lamp systems and IEC 60825-1:2001 (i.e. Edition 1.2) Safety of Laser Products - Part 1:
Equipment Classification and Requirements. Ensure that when using the LEDs, there are no issues with the following points:
- LEDs have been removed from the scope of IEC 60825-1 since IEC 60825-1:2007 (i.e. Edition 2.0) was published. However,
depending on the country/region, there are cases where the requirements of the IEC 60825-1:2001 specifications or
equivalent must be adhered to.
- LEDs have been included in the scope of IEC 62471:2006 since the release of the specification in 2006.
- Most Nichia LEDs will be classified as the Exempt Group or Risk Group 1 according to IEC 62471:2006. However, in the case
of high-power LEDs containing blue wavelengths in the emission spectrum, there are LEDs that will be classified as Risk
Group 2 depending on the characteristics (e.g. radiation flux, emission spectrum, directivity, etc.)
- If the LED is used in a manner that produces an increased output or with an optic to collimate the light from the LED, it may
cause damage to the human eye.
● If an LED is operated in a manner that emits a flashing light, it may cause health issues (e.g. visual stimuli causing eye discomfort).
The system should be designed to ensure that there are no harmful effects on the human body.
