lPacking Specification

ROHM LED products are being shipped with desiccant (silica gel) concluded in moisture-proof bags.

Pasting the moisture sensitive label on the outer surface of the moisture-proof bags or enclosing the humidity indication card

inside the bag is available upon request.

Please contact the nearest sales office or distributer if necessary.

lAttention Points In Handling

0.8mm

(Fig-1)

0.8mm

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

0.85mm

0.8mm

As for a recommendable solder pattern, Please refer to Fig-1.

The size and direction of the pad pattern depend on the condition of the PCB.

Thorough design review is recommended before the final designing

PCB Bonding Direction

This product of structured with rear/bottom electrode to be soldered.

The formation of solder fillet is not guaranteed due to its electrode shape.

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

influence 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 first and second soldering process.

Min.1 min Max. 40sec

(Fig-2)

Emitting Direction

Mold

3.HANDLING AFTER MOUNTING (Fig-3)

Outside Force

As shown in the drawing on the right, in case outside force of

about 700g is given to the device, stress is concentrated to the

Substrate

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.

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 or less.

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 moisturet

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 changed 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, 12～24 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.
