PRECAUTIONARY NOTES

1. Handling precautions

For automated pick and place, Avago has tested nozzle

size below made with urethane material to be working

fine with this LED. However, due to the possibility of

variations in other parameters such as pick and place

machine maker/model and other settings of the ma-

chine, customer is recommended to verify the nozzle

selected.

d. Control of assembled boards

- If the PCB soldered with the LEDs is to be

subjected to other high temperature processes,

the PCB need to be stored in sealed MBB with

desiccant or desiccator at <5%RH to ensure that

all LEDs have not exceeded their floor life of 672

hours.

e. Baking is required if:

- The HIC indicator is not BROWN at 10% and is

AZURE at 5%.

- The LEDs are exposed to condition of >30°C /

60% RH at any time.

- The LED floor life exceeded 672hrs.

The recommended baking condition is: 60±5ºC

for 20hrs. Baking should only be done once.

f. Storage

- The soldering terminals of these Avago LEDs

are silver plated. If the LEDs are being exposed

in ambient environment for too long, the silver

plating might be oxidized and thus affecting its

solderability performance. As such, unused LEDs

must be kept in sealed MBB with desiccant or in

desiccator at <5%RH.

3. Application precautions

a. Drive current of the LED must not exceed the

maximum allowable limit across temperature as

stated in the datasheet. Constant current driving is

recommended to ensure consistent performance.

b. LED is not intended for reverse bias. Do use other

appropriate components for such purpose. When

driving the LED in matrix form, it is crucial to ensure

that the reverse bias voltage is not exceeding the

allowable limit of the LED.

c. Avoid rapid change in ambient temperature

especially in high humidity environment as this will

cause condensation on the LED.

d. If the LED is intended to be used in outdoor or harsh

environment, the LED leads must be protected

with suitable potting material against damages

caused by rain water, oil, corrosive gases etc. It is

recommended to have louver or shade to reduce

direct sunlight on the LEDs.

4. Eye safety precautions

LEDs may pose optical hazards when in operation. It is

not advisable to view directly at operating LEDs as it

may be harmful to the eyes. For safety reasons, use ap-

propriate shielding or personal protective equipments.

Note:

1. Nozzle tip should touch the LED flange during pick and place.

2. Outer dimensions of the nozzle should be able to fit into the

carrier tape pocket.

2. Handling of moisture-sensitive device

This product has a Moisture Sensitive Level 2a rating

per JEDEC J-STD-020. Refer to Avago Application Note

AN5305, Handling of Moisture Sensitive Surface Mount

Devices, for additional details and a review of proper

handling procedures.

a. Before use

- An unopened moisture barrier bag (MBB) can

be stored at <40°C/90%RH for 12 months. If the

actual shelf life has exceeded 12 months and

the humidity Indicator Card (HIC) indicates that

baking is not required, then it is safe to reflow the

LEDs per the original MSL rating.

- It is recommended that the MBB not be opened

prior to assembly (e.g. for IQC).

b. Control after opening the MBB

- The humidity indicator card (HIC) shall be read

immediately upon opening of MBB.

- The LEDs must be kept at <30°C / 60%RH at all

times and all high temperature related processes

including soldering, curing or rework need to be

completed within 672 hours.

c. Control for unfinished reel

- Unused LEDs must be stored in a sealed MBB

with desiccant or desiccator at <5%RH.
