All rights reserved. 6/8 2013.08 - Rev.C Data Sheet SML-21 series lAttention Points In Handling This product was developed as a surface mount LED especially suitable for reflow soldering. 1.1m Please take care of following points when using this device. 1.25 1.DESIGNING OF PCB 1.1m As for a recommendable solder pattern, Please refer to Fig-1. 1.25 The size and direction of the pad pattern depends on the condition of the PCB, So, please investigate about the adjustmentthoroughly before designing. 2.SOLDERING (Sn-Cu, Sn-Ag-Cu, Sn-Ag-Bi-Cu) LED products do not contain reinforcement materials such as glass fillers. Therefore, thermal stress by soldering greatly influences its reliability. The temperature conditions for reflow soldering should therefore be set up according to the characteristic of this product. (See Fig-2) Number of reflow process shall be max 2 times and these processes shall be performed in a row. PCB Bonding Direction (Fig-1) Max.260ºC, Within 10sec 140 to 180ºC 230 to 260ºC Min.1 min Max. 40sec (Fig-2) Emitting Cooling process to normal temperature shall be required Mold Outside between the first and the second soldering process. 3.HANDLING AFTER MOUNTING Substrat As shown right drawing, in case outside force of around1kg is given to the device, stress is concentrated to the jointed part between mold resin and substrate. Therefore there is a possibility to breat the device or PCB. PCB Soldering part Careful handing is needed as ROHM cannot guarantee the falling of the device by outside force after mounting. 4.WASHING Please note the following points when washing is required after soldering. 4-1) WASHING SOLVENT Isopropyl alcohol or other alcohol solvent is recommendable. 4-2) TEMPERATURE Below 30ºC, immersion time ; within 3 minutes. 4-3) ULTRA SONIC WASHING Below 15/1 litter of solvent tub. 4-4) COOLING Below 100ºC within 3 minutes. 5.EROSION GAS Utilization in erosion gas atmosphere may degenerate the plating surface which might cause deterioration of solder strength, optical characteristics, or functions. Please take precautions against occurrence of gas from the surrounding parts on the occasion of custody, and also after mounted on circuit board. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved. 7/8 2013.08 - Rev.C Data Sheet SML-21 series 6.STORAGE At reflow soldering, the reliability of this product is often influenced by moisture absorption so we apply the packaging with moisture proof for better condition is use, please also note that 6-1) Not to be opened before using. 6-2) To be kept in our moisture proof packaging with some desiccant (SILICA GEL) after opening it. To be baked in case the SILICA GEL indicator its color from either blue to clear or green to pink. 6-3) Please use within 168 hours after the package was opened. (Condition at 30ºC, max.70%Rh.) In case it is not used within 168 hours, please put it back into our packaging. 6-4) BAKING Please bake under reel condition at 60ºC, 12 to 24 hours (max.20%Rh) after un-sealing. While baking is done, the reel and emboss tape may be easily deformed. Please be careful not to give any stress. 7.LIFE TIME This product will cause reduction of luminous intensity depending on the using conditions and environmental. Please inquire our sales contact if long life time is required on your application. www.rohm.com © 2013 ROHM Co., Ltd.
