Packing Structure • The LEDs are packed in cardboard boxes after taping Please refer to figure : page 8 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 Luxpia. • If a box shows noticeable damage upon arrival at the User’s warehouse. It is recommended that the User submit a claim to Luxpia within one weeks after arrival of the products. If the submitted notice regarding the damage exceeds the aforementioned two weeks, it will be treated in the manner shown in term 13. Different and Better 9/17 LWH1035 9.

Cautions White LEDs are devices which are materialized by combining Blue LEDs and special phosphors. Consequently, the color of White LEDs is changed a little by an operating current. Care should be taken after due consideration when using LEDs. (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. Different and Better 13/17 LWH1035 (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. • Recommended soldering conditions Reflow Soldering Hand Soldering Lead Solder Lead-free Solder Temperature 350℃ Max Pre-heat 180~200℃ 120~150℃ Soldering time 3sec Max Pre-heat time 120sec Max 120sec Max (one time only) Peak temperature 240℃ Max 260℃ Max Soldering time 10sec Max 10sec Max refer to refer to Temperature Temperature 1 2 - profile ○ - profile ○ * After reflow soldering rapid cooling should be avoided. Temperature-profile (Surface of circuit board) Use the conditions shown to the under figure. 1 : Lead Solder] 2 : Lead-free Solder] [○ [○ [Recommended soldering pad design] Use the following conditions shown in the figure. Different and Better 14/17 LWH1035 • 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. (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=0.5mA) (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. Different and Better 15/17 LWH1035 12.
