(2) please avoid stress to resin at high temperature. 2. termination processing (1) in case of termination processing, please fix the termination (2) processing position, 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 formin to avoid the physical stress on resin. (2) using spacer between leds 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:///

(deviation of vf value will cause deviation of current in led.) ? furthermore, for off mode, please do not apply voltage neither forward nor reverse. especially, fo r the products with the ag-paste used in the die bonding, theres high possibility to cause electro migration and result in function failure. 2. operation life span theres possibility for intensity of light drop according to working conditions and environments (applied current, surrounding temperature 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 (chlorine gas, sulfured gas) or alkali gas (ammonia), it may 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) aterials. all of the above will cause function failure of the products. therefore, please pay attention to the storage environment for mounted 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, theres 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:///
