Therefore if sudden thermal and mechanical shock are given, destruction or inferiority of luminous intensity may occur. Please take care of the handling. ■ FIXATION METHOD 1. ATTENTION POINTS (1) Please do not give excessive heat over storage temperature to resin.In case that the product has to be heated in oven for the glue fixing of surface mount pats, this LED should be mounted after the glue fixing. (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 nonlighting 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 Please using. 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. www.rohm.com © 2015 ROHM Co., Ltd.

(2) Please avoid stress to LED lamp during soldering. (3) In case of double peak flow soldering, the temperature gap during 1st and 2nd soldering to be less than 100 degree C. <Recommendable soldering conditions> SOLDERING OPERATION ARTIICLE TEMP TIME Soldering Dip Pre-heat Max. 100ºC Soldering Bath Max. 265ºC Soldering Iron Max. 400ºC Remarks 60sec Max. In case of double peak flow soldering, the operation 5sec Max. time is counted from the beginning of 1st peak to the end of 2nd peak. 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-lighting 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 Cleaning by solvent Temperature of solvent Immersion time Ultrasonic out Cleaning time : Max. 45ºC : Max. 3min : Ultrasonic out : 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 recommend 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 LED’s body absorb moisture highly, destruction or inferiority of luminous intensity may occur. www.rohm.com © 2015 ROHM Co., Ltd. All rights reserved. 4/5 2015.09 - Rev.C SLI-325(W) Series Data Sheet ■ APPLICATION METHOD 1. Precaution for Drive System and Off Mode ・Design the circuit without the electric load exceeding the ABSOLUTE MAXIMUM RATING that applies on the products. ・If drive by constant voltage, it may cause current deviation of the LED and result in deviation of luminous intensity, so we recommend to drive by constant current. (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, 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 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) materials. 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, 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). www.rohm.com © 2015 ROHM Co., Ltd.
