4.PACKAGING
· The LEDs are packed in cardboard boxes after packaging in anti-electrostatic bags.
According to the
total delivery amount, cardboard boxes will be used to protect the LEDs from mechanical shocks during
transportation.
Please refer to figure’s page.
The label on the minimum packing unit bag shows;
Part Number, Lot Number, Ranking, Quantity
· The boxes are not water resistant and therefore must be kept away from water and moisture.

7.CAUTIONS
(1) Lead Forming
· When forming leads, the leads should be bent at a point at least 3mm from the base of the epoxy bulb.
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
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 epoxy resin and this will degrade the LEDs.
(2) 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 leadframes are comprised of a silver plated copper alloy. The silver 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.
(3) 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.
