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
· When moisture is absorbed into the SMT package it may vaporize and expand during soldering.
There is a possibility that this can cause exfoliation of the contacts and damage to the optical
characteristics of the LEDs.
to a minimum in the package.
For this reason, the moisture proof package is used to keep moisture
· The moisture proof package is made of an aluminum moisture proof bag.
A package of
a moisture absorbent material (silica gel) is inserted into the aluminum moisture proof bag.
The silica gel changes its color from blue to pink as it absorbs moisture.
(2) Storage
· Storage Conditions
Before opening the package :
The LEDs should be kept at 30°C or less and 90%RH or less. The LEDs should be used within a
year.
When storing the LEDs, moisture proof packaging with absorbent material (silica gel)
is recommended.
After opening the package :
The LEDs should be kept at 30°C or less and 70%RH or less.
The LEDs should be soldered
within 168 hours (7days) after opening the package.
stored in moisture proof packages, such as sealed containers with packages of moisture absorbent
material (silica gel). It is also recommended to return the LEDs to the original moisture proof
If unused LEDs remain, they should be
bag and to reseal the moisture proof bag again.
· If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage
time, baking treatment should be performed using the following conditions.
Baking treatment : more than 24 hours at 65 ± 5°C
· Nichia LED electrodes are silver plated copper alloy. The silver surface may be affected by
environments which contain corrosive substances. 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.

(N2 reflow is recommended.)
ꢀ Although the recommended soldering conditions are specified in the above table, reflow or hand
soldering at the lowest possible temperature is desirable for the LEDs.
ꢀ A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.

(Unit : mm)
· Occasionally there is a brightness decrease caused by the influence of heat or ambient atmosphere
during air reflow. It is recommended that the User use the nitrogen reflow 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.
· When soldering, do not put stress on the LEDs during heating.
· After soldering, do not warp the circuit board.
(5) Cleaning
· It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs.
When using
other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the
resin or not.
· Do not clean the LEDs by the ultrasonic.
Freon solvents should not be used to clean the LEDs because of worldwide regulations.
When it is absolutely necessary, the influence of ultrasonic
cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition.
Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur.

<Cat.No.060915>
(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 precautions
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.
Criteria : (VF > 2.0V at IF=0.5mA)
(7) Others
· NSSB426C complies with RoHS Directive.
· Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum rating
when using the LEDs with matrix drive.
· 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.
