(2) please avoid stress to resin at high temperature. 2. termination processing (1) in case of termination processing, please fix the termination(2) processing p osition, and process the reverse side of led body.if stress is given during processing, it may cause non-lighting failure. (3) please process before soldering. 3. assembly on pc board (1) in case of soldering on pcb, if the operation is done with stress, it may cause non-lighting failure during soldering or using. please design the through-holes of pcb suitable for lead pins space or lead pins space after forming to avoid the physical stress on resin. (2) using spacer between led s body and pcb is recommended.in case of direct mount on pcb(slr/sli-343 series), please take care about clinch of led pins to avoid the remained stress and solder heat stress. enough evaluation is requested before deciding assembly and soldering conditions. please consult with us if any problems in the evaluation stage. downloaded from: http:///

(3) in case of double peak flow soldering, the temperature gap during 1st and 2nd soldering to be less than 100 degree c. artiicle soldering temp operation time remarks soldering dip pre-heat max. 100oc 60sec max. - soldering bath max. 265oc 5sec max. in case of double peak flow soldering, the operationtime is counted from the beginning of 1 st peak to the end of 2 nd peak. soldering iron max. 400oc 3sec max. the iron should not touch the led s body. 5. cleaning in case of cleaning, some solvents may cause damage of resin or cause non-li ghting failure, so please check the solvent before actual use. the recommendable cleaning solvent is alcoholic one such as isopropyl alcohol. recommendable cleaning conditions method conditions cleaning by solvent temperature of solvent : max. 45oc immersion time : max. 3min cleaning by solvent ultrasonic out : ultrasonic out cleaning time : max. 3min 6. recommendable round pattern round pattern depends on the material pcb, density and circuit arrangement.our recommendation is as follow : attention on storaging storage in dry box is most desirable, but if it is not possible, we r ecommend following conditions. recommendable storage conditions article temperature humidity expiration date conditions 5 to 30oc max.60%rh within 1 year poor storage conditions may cause some failure as bellow. (1) lead pins may corrode if it is stored in the environment of high temperature and humidity and lead to defective soldering. (2) in case of soldering after leds body absorb moisture highly, destruction or inferiority of luminous intensity may occur. downloaded from: http:///

(deviation of vf value will cause deviation of current in l ed.) ? furthermore, for off mode, please do not apply voltage neither forward nor reverse. especially, for the products with the ag-paste used in the die bonding, there s high possibility to cause electro migration and result in function failure. 2. operation life span there s possibility for intensity of light drop according to working conditions and environments (applied current, surrounding tempera ture and humidity, corrosive gases ), please call our sales staffs for inquiries about the concerned application below. (1) longtime intensity of light life(2) on mode all the time 3. usage the product is led. we are not responsible for the usage as the diode such as protection chip, rectifier, switching and so on. others 1. surrounding gas notice that if it is stored under the condition of acid gas (ch lorine gas, sulfured gas) or alkali gas (ammonia), it m ay result in low soldering ability (caused by the change in quality of the plating surface ) or optical characteristics changes (light intensity, chrominance) and change in quality of die bonding (ag-paste) materials. all of the above will cause function failure of the products. therefore, please pay attention to the storage environment for mo unted product (concern the generated gas of the surrounding parts of the products and the atmospheric environment). 2. electrostatic damage the product is part of semiconductor and electrostatic sensitive, there s high possibility to be damaged by the electrostatic discharge. please take appropriate measures to avoid the static electricity from human body and earthing setting of production equipment. the resistance values of electrostatic discharge (actual values) are different varies with products, therefore, please call our sales staffs for inquiries. 3. electromagnetic wave please concern the influence on led in case of application with strong electromagnetic wave such as ih(induction heating). downloaded from: http:///
