SML-31 Series Data Sheet lPrecaution (Surface Mount Device) 1.Storage If the product is heated during the reflow under the condition of hygroscopic state, it may vaporize and expand which will influence the performance of the product. Therefore, the package is waterproof. Please use the product following the conditions: • Using Conditions Classification Temperature Humidity Expiration Date Remark Within 1 year 1 Before using 5 to 30ºC 30 to 70%RH Storage with waterproof package from Receiving 2 After opening Please storing in the airtight container with 5 to 30ºC Below 70%RH Within168h package our desiccant (silica gel) • Baking Bake the product in case of below: 1 The expiration date is passed. 2 The color of indicator (silica gel) turned from blue to colorless or from green to pink. (Even if the product is within the expiration date.) • Baking Conditions Temperature Time Humidity 60±3ºC 12 to 24h Below 20%RH • Bake products in reel. • Reel and embossed tape are easy to be deformed when baking, so please try not to Remark apply stress on it. • Recommend bake once. 2.Application Methods 2-1. 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. 2-2. 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 2-3.Applied Stress on Product The top of the LED is very soft, which the silicon resin is used as sealing resin. Therefore, please pay attention to the overstress on it which may influence its reliability. 2-4.Usage The Product is LED. We are not responsible for the usage as the diode such as Protection Chip, Rectifier, Switching and so on. www.rohm.com © 2014 ROHM Co., Ltd. All rights reserved. 7/9 2014.12 - Rev.D

SML-31 Series Data Sheet 3. Others 3-1. 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). 3-2. 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 of production equipment. The resistance values of electrostatic discharge (actual values) vary with products, therefore, please call our Sales staffs for inquiries. 3-3. Electromagnetic Wave Please concern the influence on LED in case of application with strong electromagnetic wave such as IH (Induction heating). 4.Mounting 4-1. Soldering • No resin hardening agent such as filler is used in the sealing resin of the product. Therefore, resin expansion and moisture absorption at humidity will cause heat stress during soldering process and finally has bad influence on the product’s reliability. • The product is not for flow soldering. • Do not expose the product in the environment of high temperature (over 100ºC) or rapid temperature shift (within 3ºC of temperature gradient) during the flow soldering of surrounding parts. • Please set appropriate reflow temperature based on our product usage conditions and specification. • The max for reflowing is 2 times, please finish the second flow soldering and flow soldering with other parts within the usage limitation after open the moistureproof package. • Compare with N2 reflow, during air reflow, because of the heat and surrounding conditions, it may cause the discoloration of the resin. • For our product that has no solder resist, because of its solder amount and soldering conditions, one of its specific characteristics is that solder will penetrate into LED. Thus, there's high possibility that will influence its reliability. Therefore, please be informed, concerning it before using it. 4-2. Automatic Mounting 4-2-1.Silicon Resin Sealing Product The sealing resin of LED is very soft, so please select adsorption nozzle that would not apply stress directly on the sealing section. 4-2-2.Mini Package (Smaller than 1608 size) Vibration may result in low mounting rate since it will cause the static electricity of product and adhere to top cover tape. We recommend to • set magnet on parts feeder cassette of the mounter to control the product stabilization • set ionizer to prevent electrostatic charge 4-3. Mounting Location The stress like bending stress of circuit board dividing after mounting, may cause LED package crack or damage of LED internal junction, therefore, please concern the mounting direction and position to avoid bending or screwing with great stress of the circuit board. www.rohm.com © 2014 ROHM Co., Ltd.

SML-31 Series Data Sheet 4-4. Mechanical Stress after Mounting The mechanical stress may damage the LED after Circuit Mounting, so please pay attention to the touch on product. Stress strength according to the mounting position: A>B>C>D 4-5. Soldering Pattern for Recommendation We recommend the soldering pattern that shows on the right. It will be 0.8mm different according to mounting situation of circuit board, therefore, please concern before designing. 0.8m *The product has adopted the electrode structure that it should solder with back electrode of the product. 0m.8 5mm 0.8m 4-6. Reflow Profile For reflow profile, please refer to the conditions below:(*) PCB Bonding Direction m (F(iFg-i1g)- 1) • Meaning of marks, Conditions Mark Meanings Conditions Ts Maximum of pre-heating temperature 180ºC max Ts Minimum of pre-heating temperature 140ºC min Ts Time from Ts to Ts Over 60sec. min max T Reference temperature 230 to 260ºC L t Retention time for T Within 40sec.

D *Above conditions are for reference. Therefore, evaluate by customer’s own circuit boards and reflow furnaces before using, because stress from circuit boards and temperature variations of reflow furnaces vary by customer’s own conditions. 4-7. Cleaning after Soldering Please follow the conditions below if the cleaning is necessary after soldering. Solvent We recommend to use alcohols solvent such as, isopropyl alcohols Temperature Under 30ºC within 3 minutes Ultrasonic Cleaning 15W / Below 1 liter (capacity of tank) Drying Under 100ºC within 3 minutes www.rohm.com © 2014 ROHM Co., Ltd.
