9/14 10. cautions white leds are devices which are materialized by combining blue leds and special phosphors. consequently, the color of white leds is subject to chan ge 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 products during soldering. there is a possibility that this may cause exfoliation of the contacts and damage to the optical characteristics of the leds. for this reason, the moisture-proof pack age 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 - after opening the package : the leds should be kept at 5 ? ~30 or less and ? 60%rh or less. the leds should be used within a year. when storing the leds, moisture-proof packaging with moisture-absorbent material (silicagel) is recommended. 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 recommended storage time, baking treatment should be performed using the following conditions. - baking treatment : more than 24 hours at 1255 ? (this condition is led standards which are not in the reel) ? luxpia's led electrode sections are comprised of a s ilver-plated copper alloy. the silver surface may be affected by environments which contain corrosive gases and so on. please avoid condition which may cause difficulty during soldering operations. it is recommend ed that the user use the le ds as soon as possible. ? please avoid rapid transitions in ambient temperat ure, 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 the system is designed. 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 the specification. ? the operating current should be decided after considering the ambient maximum temperature of leds.

10/14 (4) soldering conditions ? the leds can be soldered in place using the re flow soldering method. luxpia does not make any 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 pre-heat pre-heat time peak temperature soldering time condition 120~150 ? 120sec max 240 ? max 10sec max refer to profile y 200~220 ? 120sec max 260 ? max 5sec max refer to profile t temperature soldering time 350 ? max 3sec max (one time only) * after reflow soldering, rapid cooling should be avoided.

11/14 ? 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 b een 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 le ds because of worldwide re gulations. do not clean the leds by the ultrasonic. when it is absolutely necess ary, the influence of ultrasonic cleaning on the leds depends on factors such as ultrasonic power and the asse mbled 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 proper ly 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 we re 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 v f 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 : v f > 2.0v at i f =0.5 v (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 us ing equipment that has had leds incorporated into it. 11. warranty (1) luxpia warrants that its leds conform to the foregoin g specifications and that luxpia will convey good title to all leds sold. (2) luxpia disclaims all other warranties including the implied warranties of merchantability and fitness for a particular purpose. (3) in the event any led supplied by luxpia is found no t to conform to the foregoing specifications within ninety days of receipt, luxpia will repair or replace the led, at luxpia?s discretion, provided that the user (a) promptly notifies luxpia in writing of the details of th e defect (b) ships the leds at the user?s expense to luxpia for examination, and (c) the defect is due to th e negligence of luxpia and not mishandling or misuse by the user. (4) luxpia will not take responsibility for any trouble that is caused by using the le ds at conditions exceeding our specifications. (5) these specifications are applied only when a led st ands alone and it is strongly recommended that the user of the leds confirms the properties upon assembly . luxpia is not responsible for failures caused during and after assembling. it will be excepted from the rule if the failure would caused undoubtedly by luxpia.
