2、NS,現(xiàn)狀說(shuō)明：越來(lái)越多的客戶(hù)抱怨LED經(jīng)客戶(hù)使用後有缺亮、色澤不均、亮度不均等不良狀況，經(jīng)對(duì)不良品進(jìn)行分析，有大多數(shù)為客戶(hù)在測(cè)試及應(yīng)用上不當(dāng)而產(chǎn)生之不良，建立此檔案引導(dǎo)客戶(hù)正確使用LED。 present problems: more and more customers complained led have the problems of lack of brightness , inequable colour and lustre ， inequable brightness. We found that the majority customer testing and using

3、 our product in a wrong way after we test the abnormal products , so we establish this profile to lead customer using LED correctly.,4,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,LED加工的注意事項(xiàng)led processing instructions A、LED在剪腳時(shí)建議采用自動(dòng)機(jī)臺(tái)進(jìn)行剪腳，且保持刀片峰利，以防止扭距應(yīng)力拉扯膠體與支架，產(chǎn)生應(yīng)力破壞LED內(nèi)部結(jié)構(gòu)。Using the machine to cut ,and shou

4、ld keep blade sharp to protect epoxy and leadframe from twist pressure, which may make damage to the leds inside structure. B、建議LED成形加工時(shí)在焊錫前，如在焊錫後立即進(jìn)行加工，此時(shí)LED膠體內(nèi)部還存在一定的溫度，若用手碰觸或外力碰觸到膠體,因膠體特性會(huì)產(chǎn)生應(yīng)力拉扯斷第二焊點(diǎn) 。Do the figuration processing before soldering ,if do it before soldering immediately , there wou

5、ld be temperature inside the epoxy, and if touching or outside force on the epoxy, the pressure would pull the second soldering point to crack. C、支架成形形狀需要與PCB上的間距一致，以防止LED在插在PCB上有拉扯的狀況。The leadframe figuration shape should be consistent with the space on the PCB, in case that there is a pull when LE

6、D insert in the PCB.,5,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,LED加工的注意事項(xiàng)led processinginstructions D、LED在折腳加工時(shí)，建議固定LED PIN腳後進(jìn)行加工，以防止應(yīng)力的產(chǎn)生。 When curving , we suggest that processing after fix up PIN, in case of pressure . E、需離膠體2毫米才能折彎支架。 Keep 2mm from epoxy in order to twist lead frame. F、圖示如下：refer to p

7、ictures,6,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,LED加工的注意事項(xiàng) LED processing instructions,7,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,LED焊錫的注意事項(xiàng) LED soldering instructions A、LED無(wú)鉛焊錫波峰焊條件（焊錫位置距膠體距離最小為3mm)，曲線(xiàn)圖如下：the condition of wave soldering (the soldering point should keep 3mm from epoxy at least) , as the pictur

8、e:,8,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,LED焊錫的注意事項(xiàng) LED soldering instructions B、LED手焊條件：hand soldering conditions: 烙鐵溫度300度（MAX），時(shí)間3S（MAX），建議使用恆溫烙鐵。Iron temperature 300(max), time3s(max), constant temperature is better. C、LED不支持REFLLOW焊錫。 LED don not support REFLLOW soldering. D、LED避免在高溫下碰觸其膠體與PIN腳，以

9、防止應(yīng)力拉扯斷第二焊點(diǎn)。Avoid touching epoxy and PIN under high temperature, in case that pressure pull the second soldering point to crack.,9,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,LED焊錫的注意事項(xiàng) LED soldering instructions E、禁止LED在高溫下加工。Reforming under high temperature is forbidden. F、 建議客戶(hù)在經(jīng)波峰焊後加裝風(fēng)扇，以利散熱，需等LED冷卻後（最好為室

10、溫後）,再進(jìn)行下一工序加工。We suggest that installing a fan after wave soldering to dispel heat ,do not do the next process until led cool (room temperature is better),10,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,LED使用電路的注意事項(xiàng)led using circuit instructions A、建議LED使用時(shí)，需串電阻作業(yè)，以防止大電流或大電壓燒損晶片，有部分客戶(hù)投訴亮度不均及色澤不均，均為大電流或大電壓燒損所致。如

11、下電路： In order to protect chip from burning which due to high current or voltage, a resistance is needed when using LED, some customers complained that inequable colour and lustre or inequable brightness, which all because of high current or high voltage. As the picture,11,LED的使用注意事項(xiàng) LED USING INSTRU

12、CTIONS,LED使用電路的注意事項(xiàng)led using circuit instructions B、舉例說(shuō)明：examples G晶片在未串電阻的情況下，給電壓2.2V，其電流為100mA以上，其發(fā)光顏色已趨的於橙色，時(shí)間過(guò)長(zhǎng)會(huì)燒損晶片，如下圖片：the color of chip G is orange when there is no resistance and voltage is 2.2V,current is 100mA, the chip would be burned during a long time.,有加電阻Haveresistance,未加電阻NO resista

13、nce,12,LED的使用注意事項(xiàng) LED USING INSTRUCTIONS,其它 others A、靜電注意事項(xiàng)：instructions on static 針對(duì)要求防靜電之機(jī)種，要確實(shí)做好防靜電措施，以下為藍(lán)光晶片靜電燒損圖片（晶片只部分發(fā)光）： Concerning to the prevent static machines ,make sure the prevent static measures is done , the blue chip burned as the picture. (part of chip give out light ),13,LED的使用注意事
