• 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.
(7) 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. Freon solvents should not be used to clean the LEDs because of worldwide regulations. 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 will occur.
(8) 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 measurements
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=0.5㎃
(9) Others
• This LED complies with RoHS Directive.
• 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 customer not reverse engineer by disassembling or analysis of the LEDs without having prior written
consent from Luxpia. When defective LEDs are found, the User shall inform Luxpia directly before
disassembling or analysis.
• The warranties of quality set forth herein are exclusive. All previous negotiations and agreements not
specifically incorporated herein are superseded and rendered null and void.
• Both parties shall sincerely try to find a solution when any disagreement occurs regarding these
specifications.
• These specifications can be revised upon mutual agreement.
• Luxpia understands that the User accepts the content of these specifications, if the User does not return
these specifications with signatures within 3 weeks after receipt.
• The LEDs described in the specification are intended to be used for ordinary electronic equipment (such as
office equipment, communications equipment, 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)
