sml-z1 series l attention points in handling this product was developed as a surface mount led especially suitable for reflow soldering. please take care of following points when using this device. 1.designing of pcb as for a recommendable solder pattern, please refer to fig-1. the size and direction of the pad pattern depends on the condition of the pcb, so, please investigate about the adjustment thoroughly 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 influence 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. cooling process to normal temperature shall be required between first and second soldering process. 3.use of automatic mounting machine as for this product, the silicone resin is used as encapsulate material and the sealing part on top of led is soft. therefore, please make sure not to apply the pressure upon it, as it might influence reliability. moreover, please use the adsorption nozzle when you use the automatic mounting machine so as not to apply the force directly to this top sealing part. 4.handling after mounting as shown right drawing, in case outside force is given to the device, stress is concentrated to the jointed part between mold resin and substrate. therefore there is a possibility to breath the device or pcb. careful handing is needed as rohm cannot guarantee the falling of the device by outside force after mounting. min.1 min max. 40sec max.2 5 0 oc, within 140 to 180 oc 23 0 to (fig - 1) pcb bonding direction 2.6mm 1.5mm 1.5mm 1.5mm (fig - 2 ) soldering pcb emitting direction outside 9/10 2013.08 - rev.c www.rohm.com ? 2013 rohm co., ltd. all rights reserved. data sheet
sml-z1 series 5.washing please note the following points when washing is required after soldering. 5-1) washing solvent isopropyl alcohol or other alcohol solvent is recommendable. 5-2) temperature below 30oc, immersion time ; within 3 minutes. 5-3) ultra sonic washing below 15/1 litter of solvent tub. 54) cooling below 100oc within 3 minutes. 6.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. 7.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 7-1) not to be opened before using. 7-2) 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 changed its color from either blue to clear or green to pink. 7-3) please use within 72 hours after the package was opened. (condition at 30 o c, max.70%rh.) in case it is not used within 72 hours, please put it back into our packaging. 7-4) baking please bake under reel condition at 60 o c, 40 48 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. 10/10 2013.08 - rev.c www.rohm.com ? 2013 rohm co., ltd. all rights reserved. data sheet
