4.PACKAGING
· The LEDs are packed in cardboard boxes after packaging in anti-electrostatic bags.
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) Cautions
· The devices are UV light LEDs.
The LED during operation radiates intense UV light,
which precautions must be taken to prevent looking directly at the UV light with unaided eyes.
Do not look directly into the UV light or look through the optical system.
When there is a possibility
to receive the reflection of light, protect by using the UV light protective glasses so that light should not
catch one’s eye directly.
· Put the caution label on the cardboard box.

DO NOT VIEW DIRECTLY WITH

CLASS 1M LED PRODUCT
(2) Lead Forming
· When forming leads, the leads should be bent at a point at least 3mm from the base of the lead.
Do not use the base of the leadframe as a fulcrum during lead forming.
· Lead forming should be done before soldering.
· Do not apply any bending stress to the base of the lead. The stress to the base may damage the LED’s
characteristics or it may break the LEDs.
· When mounting the LEDs onto a printed circuit board, the holes on the circuit board should be exactly
aligned with the leads of the LEDs. If the LEDs are mounted with stress at the leads, it causes
deterioration of the lead and this will degrade the LEDs.
(3) Storage
· The LEDs should be stored at 30°C or less and 70%RH or less after being shipped from Nichia and
the storage life limits are 3 months.
If the LEDs are stored for 3 months or more, they can be stored
for a year in a sealed container with a nitrogen atmosphere and moisture absorbent material.
· Nichia LED leads are comprised of a gold plated Iron alloy. 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 LEDs be used as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where
condensation can occur.
(4) 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 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).
The LEDs
should be used the light detector etc. when testing the light-on. Do not stare into the LEDs when testing.
· Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower,
or the LEDs do not light at the low current.
