lAttention 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.

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 30ºC, 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 60ºC, 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.
