[SML-A1x series] 　　　　 [Data Sheet] ■Precaution (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 ①Before using 5〜30℃ 30〜70%RH Storage with waterproof package from Receiving ②After opening Please storing in the airtight container 5〜30℃ Below 70%RH Within 168h package with our desiccant (silica gel) ・Baking Bake the product in case of below: ①The expiration date is passed. ②The 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±3℃ 12〜24h Below 20%RH ・Bake products in reel. ・Reel and embossed tape are easy to be deformed when baking, Remark so please try not to 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, thereʼs high possibility to cause electro migration and result in function failure. ２－２．About Derating 　It is considered that derating characteristics will not result in LED chip's electrical destruction. Even within the derating, the reliability and luminous life can be affected depending on operating conditions and ambient environment. So we would be appreciate it if you can confirm with your application again. ２－３．About product life Depending on operating conditions and environment(applied current, ambient temperature and humidity, corrosive gas), decreasing of luminosity and change of chromaticity may occur even within the specification conditions. Please contact our sales office if you use it for the following applications. ①It requires long luminosity life ②It is always lit ２－４．Applied Stress on Product No resin hardening agent such as filler is used in the sealing resin of the product. Therefore, please pay attention to the overstress on it which may influence its reliability. ２－５．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 ©2018 ROHM Co., Ltd.

[SML-A1x 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 cause die bonding (Ag-paste) materials. All of the above will 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, thereʼs 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. Especially, InGaN type LEDs have lower resistance value of electrostatic discharge and it is recommended to introduce the ESD protection circuit. The resistance values of electrostatic discharge (actual values) vary with products, therefore, please call our Sales staffs for inquiries. ３－３． Electromagnetic Wave Applications with strong electromagnetic wave such as, IH cooker, will influence the reliability of LED, therefore please evaluate before using it. ＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿ www.rohm.com ©2018 ROHM Co., Ltd.

[SML-A1x series] 　　　　 [Data Sheet] 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 productʼs reliability. ・The product is not guaranteed for flow soldering. ・Do not expose the product in the environment of high temperature (over 100℃) or rapid temperature shift (within 3℃/sec. of temperature gradient) during the flow soldering of surrounding parts. In case of carrying out flow soldering of surrounding parts without recommended conditions, please contact us for inquiries. ・Please set appropriate reflow temperature based on our product usage conditions and specification. ・The max for reflowing is 2 times, please finish the second reflow 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. Therefore, the magnet should be set on parts feeder cassette of the mounter to control the product stabilization. In addition, it is recommended to 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. Stress strength according to he mounting position: A＞B＞C＞D 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. ４－５．Soldering Pattern for Recommendation 1.2mm We recommend the soldering pattern that 0.8mm shows on the right. It will be different according to mounting situation of circuit board, therefore, 0.9mm 2.1mm 0.9mm 3.3mm please concern before designing.
