CAUTIONS- Super Bri ght LED
(1) Lead Forming
1. At least 5mm from the base of the epoxy bulb should be keep when forming leads.
1. Do not use the base of the leadframe as a fulcrum during lead forming.
Lead forming should be done before soldering.
1. Because the stress to the base may damage the characteristics or it may break the LEDs, do not apply any
bending stress to the base of the lead
1. When mounting the LEDs onto a PCB, the holes on the circuit board should be exactly aligned with the leads of
the LEDs. Stress at the leads should be avoid when the LEDs are mounted on the PCB, because it causes damage to the
epoxy resin and this will degrade the LEDs.
(2) Storage
a. The LEDs should be stored at stored at 30 ℃ or less and 70%RH or less after being shipped and the storage life limits
are 3 months.
b. If the LEDs are stored more then 3 months, they can be stored for a year in a sealed container with a nitrogen
atmosphere and moisture absorbent material.
c. Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where condensation
can occur.
(3) Static Electricity
a. Static electricity or surge voltage damages the LEDs.
b. It is recommended that a wristband or an anti-electrostatic glove be used when handling the LEDs.
c. All devices, equipment and machinery must be properly grounded.
d. It is recommended that measures be taken against surge voltage to the equipment that mounts the LEDs.
e. 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)
(4) Heat Generation
a. Thermal design of the end product was most importance. Please consider the heat generation of the LED when making the
system design.
b. The thermal resistance of the circuit board and density of LED placement on the board, as well as other components was
the important factor affecting the coefficient of temperature increase per input electric power. It must be avoid
intense heat generation and operate within the maximum ratings given in the specification.
c. The operating current should be decided after considering the ambient maximum temperature of LEDs.
(5) Cleaning
1. 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 resin or not. Freon solvents should not be used
to clean the LEDs because of worldwide regulations.
1. Do not clean the LEDs by the ultrasonic. 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 would occur.
• A minimal cathode area of 0.18 × 0.18 inch2 × 2 is recommended for P4 LEDs.
• Soldering LEDs at not less than 3 mm from the base of the package and below the tie-bar is recommended.
• The LED soldering specification is shown as below (suitable for both leaded solder and lead-free solder).

Manual soldering onto a PCB is not recommended.
Recommended soldering profile:

* Various lead-free solder types are required for different solder conditions. Please contact your Cree sales
representa tive for details.
• Do not apply any stress to the LED package, particularly when heated.
• LEDs must not be re-used once extracted from a PCB.
• After soldering the LEDs, the package should be protected against mechanical shock or vibration until the LEDs have
reached 40ºC or below.
• Mechanical stress on the LEDs may cause PCB warpage, clinching or cutting of the LED leads.
• When clamping LEDs during soldering is required, be sure that no mechanical stress is exerted on the LEDs.
• Lead cutting must be performed at normal room temperature (25°C). Lead cutting at an elevated temperature can cause LED
(7) Others
l Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum rating when using the LEDs
with matrix drive. Keeping the Normal Forward to 20 mA.
l 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 Hoprled 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).

c.User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written consent from Hopr
led. When defective LEDs are found, the User shall inform Hoprled directly before disassembling or analysis.
d. The LEDS regular service condition: at 30 ℃ or less and 50%RH or less and 20Ma or less.
e.The appearance and specifications of the product may be modified for improvement without notice.
f. The formal specifications must be exchanged and signed by both parties before large volume purchase begins.
