4.PACKAGING
· The LEDs are packed in cardboard boxes after taping.
Please refer to figure’s page.
The label on the minimum packing unit shows ; Part Number, Lot Number, Ranking, Quantity
· In order to protect the LEDs from mechanical shock, we pack them in cardboard boxes for transportation.
· The LEDs may be damaged if the boxes are dropped or receive a strong impact against them,
so precautions must be taken to prevent any damage.
· The boxes are not water resistant and therefore must be kept away from water and moisture.
· When the LEDs are transported, we recommend that you use the same packing method as Nichia.

7.CAUTIONS
(1) Moisture Proof Package
· To prevent moisture absorption during transportation and storage, reels are packed in aluminum
envelopes that contain a desiccant with a humidity indicator.
(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 : 5 ~ 30 °C
Humidity : 60%RH Max.
The devices should be mounted as soon as possible after unpacking. If you store the unpacked reels,
please store them in the dry box or seal them into the envelope again.
· If the devices have been stored over 6 months or unpacked over 15 days, it should be baked
under the following conditions.
Baking conditions : 60°C × 12 hours or more (reeled one)
100°C × 45 minutes or more (loose one)
150°C × 15 minutes or more (loose one)
· Nichia LED electrode sections are comprised of a gold plated. The gold surface may be
affected by environments which contain corrosive gases and so on. Please avoid conditions which
may cause the LED to corrode, tarnish or discolor. This corrosion or discoloration may cause difficulty
during soldering operations. It is recommended that the User use the LEDs as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially in high humidity environments where
condensation can occur.
(3) Heat Generation
· Thermal design of the end product is of paramount importance.
Please consider the heat generation
of the LED when making the system design. The coefficient of temperature increase per input
electric power is affected by the thermal resistance of the circuit board and density of LED placement
on the board, as well as other components. It is necessary to avoid intense heat generation and operate
within the maximum ratings given in this specification.
· The operating current should be decided after considering the ambient maximum temperature of LEDs.

(4) Soldering Conditions
· The LEDs can be soldered in place using the reflow soldering method.
Nichia cannot make a
guarantee on the LEDs after they have been assembled using the dip soldering method.

· Repairing should not be done after the LEDs have been soldered.
When repairing is unavoidable,
a double-head soldering iron should be used.
It should be confirmed beforehand whether the
characteristics of the LEDs will or will not be damaged by repairing.
· Reflow soldering should not be done more than two times.
· Before soldering every time, make baking to units. By manual soldering, there is possibility of crack
due to the moisture absorption in the resin portion.
· When soldering, do not put stress on the LEDs during heating.
· After soldering, do not warp the circuit board.
· Handle the devices only after temperature is cooled down.
(5) Washing
· When washing after soldering is needed, following conditions are requested.
a) Washing solvent: Ak – 225 Alcohol
b) Temperature and time: 50°C or less × 30 seconds Max, or 30°C or less × 3 minutes Max.
c) Ultrasonic washing: Basically Not accepted.

(6) Static Electricity
· Static electricity or surge voltage damages the LEDs.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.
· All devices, equipment and machinery must be properly grounded.
It is recommended that measures be taken against surge voltage to the equipment that mounts the LEDs.
· When inspecting the final products in which LEDs were assembled, it is recommended to check
whether the assembled LEDs are damaged by static electricity or not.
It is easy to find
static-damaged LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended).
· Damaged LEDs will show some unusual characteristics such as the leak current remarkably
increases, the forward voltage becomes lower, or the LEDs do not light at the low current.
(7) Others
· It is requested to avoid any stress added to the resin portion while it is heated.
· It is requested to avoid any friction by sharp metal nail etc, to the resin portion.
· The current limiting resistor should be placed in the circuit in order for LED to work within its rating.
Also avoid reverse voltage (overcurrent) applied instantaneously when ON or OFF.
· When assembling the circuit board into the finished products, care must be taken to avoid the component
parts from touching other parts.
· The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent
looking directly at the LEDs with unaided eyes for more than a few seconds.
· Flashing lights have been known to cause discomfort in people; you can prevent this by taking
precautions during use. Also, people should be cautious when using equipment that has had LEDs
incorporated into it.
· The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such
as office equipment, communications equipment, measurement instruments and household appliances).
Consult Nichia’s sales staff in advance for information on the applications in which exceptional quality
and reliability are required, particularly when the failure or malfunction of the LEDs may directly
jeopardize life or health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor
control systems, automobiles, traffic control equipment, life support systems and safety devices).
· User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written
consent from Nichia.
When defective LEDs are found, the User shall inform Nichia directly before
disassembling or analysis.
· The formal specifications must be exchanged and signed by both parties before large volume purchase begins.
· The appearance and specifications of the product may be modified for improvement without notice.
