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.
For this reason, the moisture proof package is used to keep
moisture to a minimum in the package.
• A package of a moisture absorbent material (silica gel) is inserted into the shielding 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℃ 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℃ or less and 70%RH or less. The LEDs should be soldered
within 168 hours (7days) after opening the package. If unused LEDs remain, they should be
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 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℃
• Luxpia LED electrode sections 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
condition 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.

LGH1025Z
(4) Soldering Conditions
• The LEDs can be soldered in place using the reflow soldering method. Luxpia cannot make a
guarantee on the LEDs after they have been assembled using the dip soldering method.

• 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
9/13
LGH1025Z
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. 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.
(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 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 staticdamaged 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=10㎂)
(7) Others
• 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.
