8. Packing Specifications
(1) Moisture proof packing
-To prevent moisture absorption during transportation and storage, reels are packed in
aluminum envelopes which contain a desiccant with a humidity indicator.
Aluminum envelop
Reel
Desiccant
Polyester Zip fastener
Label
(2) Storage
-To prevent moisture absorption, it is strongly recommended that reels (in bulk or taped
should be stored in the dry box (or the desiccator) with a desiccant as the appropriate
storage place. If not, the following is recommended.
Temperature :
Humidity :
5-30 C
60%RH max
The devices should be mounted within 168H (7days) after unpacking.
If you store the unpacked reels, please store them in the dry box or seal them into
the envelop again.
(3) Environmental conditions
-This device contain silver plated electrode. So, when being exposed to enviroment which
contains corrosive gases, the silver plating becomes tarnished.
Tarnished plating may lead to poor solderbility and degradation of optical characteristics.
-Please DO NOT expose this device to corrosive atomosphere anytime (during storage,
after mounting). Please take care the above when designing your product.
-For outdoor use, necessary measures should be taken to prevent water, moisture
and salt air damage.
-This product is NOT designed with following conditions in mind.
In water, oil, medicament, organic solvent and dust-laden environment.

9. Precautions
(1) Handling with care for this product
-The light emitting area is encapsulated with soft resin materials.
Please avoid the resin area from being pressed, stressed, rubbed,
come into contact with sharp metal nail because the function,
performance and reliability of this product are negatively impacted.
(resin area)
-Please be aware that this product should not come into contact with any other parts while
incorporating in your lighting apparatus or your other products.
-When pick and place this product, it is recommended that
using the pick up nozzle with inner radius more than 4.4mm.
-Please avoid using narrow pick up nozzle, and pushing
the resin area directly.
-Bending the circuit board with soldered LEDs may cause breakage
of package. Please take care to bow, twist and warpage the PCB.

(2) Countermeasure against static electricity
-Handling of this product needs countermeasures against static electricity because this is
a semiconductor product.
-Please take adequate measures to prevent any static electricity being produced such as
the wearing of a wristband or anti-satatic gloves when handling this product.
-Every manufacturing facility in regard to the product (plant, equipment, machine, career
machine and conveyane unit) should be connected to ground and please avoid the product
to be electric-charged.
-ESD sensitivity of this product is over 1000V (HBM, based on JEITA ED-4701/304).
-After assembling the LEDs into your final products, it is recommended to check AB34
whether the assembled LEDs are damaged by static electricity (electirical leak phenomenon)
or not.
-It is easy to find static damaged LED dies by a light-on test with the minimum current value.

9. Precautions (Continued)
(3) Thermal design
-The thermal design to draw heat away from the LED junction is most critical parameter
for an LED illumination system. High operating temperatures at the LED junction adversely
affect the performance of LED’s light output and lifetime.
Therefore the LED junction temperature should not exceed the absolute maximum rating
in LED illumination system.
-The LED junction temperature while operation of LED illumination system depends upon
thermal resistance of internal LED package (Rj-s), outer thermal resistances of LED package,
power loss and ambient temperature. Please take both of the thermal design specifications
and ambient temperature conditions into consideration for the setting of driving conditions.
-For more information, please refer to application note "Thermal Management".
(4) Driving current
-A constant current is recommended as an applying driving current to this product.
In the case of constant voltage driving, please connect current-limiting resistor to each products
in series and control the driving current to keep under the absolute maximum rating forward
current value.
-Electrical transient might apply excess voltage, excess current and reverse voltage
to the product(s).
They also affect negative impact on the product(s) therefore please make sure that
no excess voltage, excess current and reverse voltage is applied to the product(s)
when the LED driver is turn-on and/or turn-off.
-For more information, please refer to application note "Driving".
(5) Lighting at a minimum current value
-In a case where the minimum current (IF min) is applied to the product, some of LED dice
in the product might look different in their brightness due to the individual difference of
the LED dice, and they are not failed.

(6) Soldering
-This product is adaptable to reflow process, and please use lead-free soldering.
Following soldering paste is recommended.
Melting temperature : 216 - 220 C.
Composition : Sn-3.5Ag-0.75Cu
T e m p e r a tu re
-The temperature profile at the top surface of the parts is recommended as shown below.

Time
-Next process of soldering should be carried out after the product has return to ambient
temperature.
-Recommemded soldering pattern is shown to the right,
but mountability and solderability need to be optimized
with actual conditions such as amount of solder,
reflow temperature the process.
9) Eye Safety
-The International Electrical Commission (IEC) published in 2006 IEC 62471
”2006 Photobiological safety of lamps and lamp systems ” which includes LEDs within its scope.
-When sorting single LEDs according to IEC 62471, almost all white LEDs can be classified
as belonging to either Exempt Group (no hazard) or Risk Group 1 (low risk).
-However, Optical characteristics of LEDs such as radiant flux,
spectrum and light distribution are factors that affect the risk group determination of the LED,
and especially a high-power LED, that emits light containing blue wavelengths,
might have properties equivalent to those of Risk Group 2 (moderate risk).
-Great care should be taken when directly viewing an LED that is driven at high current,
has multiple uses as a module or when focusing the light with optical instruments,
as these actions might greatly increase the hazard to your eyes.
-It is recommended to regard the evaluation of stand-alone LED packages as a reference
and to evaluate your final product.
