lAttention Points In Handling
1.1m
This product was developed as a surface mount LED especially suitable for reflow soldering.
Please take care of following points when using this device.
1.25
1.DESIGNING OF PCB
1.1m
1.25
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 adjustmentthoroughly before designing.
PCB Bonding Direction
(Fig-1)
2.SOLDERING (Sn-Cu, Sn-Ag-Cu, Sn-Ag-Bi-Cu)
LED products do not contain reinforcement
materials such as glass fillers.
Max.260ºC, Within 10sec
140 to 180ºC
Therefore, thermal stress by soldering greatly
influences its reliability.
230 to 260ºC
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 the first and the second soldering process.
Min.1 min Max. 40sec

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.
Soldering
part
PCB
Therefore there is a possibility to breat the device or PCB.
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.

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.
