Condition︓Ts = 85℃, I F = 140 mA
Estimated Mean Life Time︓30 000h
4-3-2. Estimation method of Mean Life Time
Variation of luminous intensity for 3 000 hours is acquired by acceleration test
under the following conditions;
Ts = 70 to 100 ℃
I F = 120 to 180 mA
Using data of from 1 000 to 3 000 hours, value (τ) , time to be decreased to 50% of
initial luminous intensity is calculated based on the linear regression showing relationship
between maintenance ratio of luminous intensity and square root of the time.
Arrhenius plot of Mean Life Time is obtained by plotting case temperature and value (τ) .
Our estimated life time of this product is “decrease to 50% of initial luminous intensity
at Ts = 85℃” .

① Please be sure to give them the soldering within 3 days under the following conditions.
Temperature: 5 ℃ to 30 ℃ Relative humidity: 60 % or less
② Storage in a dry box is recommended in case that the products not used for
a long time after opened. or repack the reels with a desiccative by the sealer and store
them under the same conditions mentioned in 6. 2. 2
③ Please perform the baking treatment under the recommended conditions in the following
cases;
・The blue indicator of silica gel changes its color or fades.
・3days passed after opened under the specified storage conditions.
・Products were stored out of storage condition.
(Recommended baking conditions):
・Products with taping
Temperature:60℃, Time:12 to 24 hours
・Single piece of the products
Temperature:100℃,Time:45 min to 2 hours.
Avoid piling up the reels or applying stress to them during baking to protect from deformation.
Please be sure to cool then to room temperature after baking.

7．Precautions
7-1.General handling
①This device adopts the silicone reflector designed aiming at the operation lifetime for a long
time. Therefore, it is a weak structure against the external stress.
Please take care that the external stress is not added to the product.
②The voltage must be applied to LED only as a forward direction.Moreover,please design
circuit diagram considering no voltage gap between Anode and Cathode during off state.
If the reverse voltage is applied to LED for a long term, the electro-migration is generated
and there is a possibility of the short-circuit of the circuit.
③This product is sensitive for electrostatic voltage and suge voltage. Static electrocity or surge
voltage can deteriorate product and its reliability. Please make sure that all devices and
equipments must be grounded. We recommend to built in zener diode or TVS(Transient
Voltage Suppression)as protection circuit against static electricity.
④This product is composed of blue LED chip and special phosphor. Color tone is possible to
vary in some degree,depending on the operating conditions such as ambient temperature
or current amount. Also it is So please verify the performance before use.
⑤Do not look directly at LEDs with unshielded eyes, or damage to your eyes may result.
⑥Materials with high thermal conductivity are used in this product in order to allow generated
heat to escape effectively out of the product. Avoid locating other heat sources(ex.resistance,
etc.)near the products on circuit board to protect the devices from the heatedamage.
Please make sure thatcasa temperture is always under 85℃ during operation, include the
self-heat.
⑦Since dust on the surface of the radiation part is hard to remove and may decrease the
luminous intensity, please handle the products in a clean, non-dusty condition.

⑧The luminous area of this product is formed with silicone resin. In the case of handling this
device, please do not push the luminous area by the sharp tools. The crack and peel off of
the emitting area, and the wire deformation are generated and it causes not lighting.
It pressurizes by the head of the width of the point 1mm referring and the load where not
lighting is generated is as follows.
⑨This product is the small size and the luminous area portion is formed by silicone resin,
there is a possibility to have a damage by the external stress.
・ In the case of the handling with the tweezers
In the case of the handling with the tweezers, please pick up the products with the sides
of the case and do not touch the luminous area.
・ In the case of the mount of the product
Please use this product after confirming the mouting condition, because there is a possibility
to have a damage by the external stress when the load is applied by the nozzle of the mouter..
⑩Please make sure not to apply any external stress to resin after mounted as well. When the
substrate bends after mounted, the product might be applied by an external stress, and the
crack will be generated in the soldering part. Please arrange the product in the direction not
stressed for the warp of the substrate after mounted.
⑪Please do not pile the substrate after this product is mounted. This product will be damaged
by the substrate, and it causes the crack of the lens and not lighting by the inner-wire
deformation or wiring disconnection.
⑫The products are not designed for the use under any of the following conditions. Please verify
their performance and reliability well enough if you use under any of the following conditions;
（１）In a place with a lot of moisture, dew condensation, briny air, and corrosive gas
(Cl,H2S,NH3,SO2,NOX,etc)
（２）Under the direct sunlight, outdoor exposure, and in a dusty place
（３）In water, oil, medical fluid, and organic solvents
⑬The silicone resin using for LED device is affected for strong acid, strong alkalinity.
Under influence by heat or the light from LED device, halogen gas is generated from
neighboring materials and may adversely affect LEDs.
Please use that you do not have any problem enough after confirmation.
⑭Guarantee covers the compliance to the quality standards mentioned in the Specifications;
however it does not cover the compatibility with application in the end-use, including
assembly and usage environment. In case any quality problems occurred in the application
of end-use, details will be separately discussed and determined between the parties hereto.

7-2. Soldering
This product is reflow ready model(within 2 itemes), but it not ready for solder dipping.
7-2-1. Reflow
①Package temperature at reflow soldering is defined in the Fig. below. However, even
when it is under the profile condition, external stress can damage the internal packages.
Please test your reflow method and verify the solderability before use.
②Giving the soldering process promptly after opened aluminum package is recommended.
Soldering process must be completed including 2nd reflow as repairing within 3days
(Temperature:5℃ to 30℃ Relative humidity:60% or less) after opend.
(Storage in a dry box after the first reflow is recommended.)

Since the thermal conduction to the products depends on the specification of the reflow
machine, and the size and layout of the PCBs please test your solder conditions carefully.
Moreover, after the reflow process, If the activator remains in the flux between anode
and cathode, the remaining activator might react during high temperature operation,
and the electro-migration is generated and there will be a possibility of a short-circuit.
Please use it after confirming the electro-migration is not generated while mounted actual

④Recommended metal mask design
Solderability depends on the reflow conditions, solder past, and materials of the PCBs etc.
Please test and verify the solderability under the actual solder method.
Moreover, it might have a risk of short-circuit(leakage)with the electro-migration by the
remining activator in the flux. Please make a suitable section and test of the metal mask
in terms of pitch size and thickness before mass production.

⑤Precautions for PCB backside dip process
Please verify your conditions carefully in giving the dip process on the backside of the PCBs,
since the warped boards caused by heat and heat itself affect the inside of the package.
It is recommended to give the reflow process after dip process.
Though it is also available to give the reflow process before the dip process, the interval of
the two processes should be as short as possible.
7-3.Cleaning
・ Avoid cleaning the PCBs, since packages and resin are eroded by cleaning.
Please use the soldering paste without need of cleaning.
・ Avoid ultrasonic cleaning
