CAUTIONS

1. Application

The LEDs described here are intended to be used for ordinary electronic equipment (such as office

equipment,

communication equipment and household applications).Consult Liteon’s Sales in advance

for information on applications in which exceptional reliability is required, particularly when the failure or

malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation, traffic

control equipment, medical and life support systems and safety devices).

2. Storage

The storage ambient for the LEDs should not exceed 30°C temperature or 70% relative humidity.

It is recommended that LEDs out of their original packaging are used within three months.

For extended storage out of their original packaging, it is recommended that the LEDs be stored

in a sealed container with appropriate desiccant or in desiccators with nitrogen ambient.

3. Cleaning

Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LEDs if necessary.

4. Lead Forming & Assembly

During lead forming, the leads should be bent at a point at least 3mm from the base of LED lens.

Do not use the base of the leadframe as a fulcrum during forming.

Lead forming must be done before soldering, at normal temperature.

During assembly on PCB, use minimum clinch force possible to avoid excessive mechanical stress.

5. Soldering

When soldering , For Lamp without stopper type and must be leave a minimum of 3mm clearance

from the base of the lens to the soldering point. To avoided the Epoxy climb up on lead frame and

was impact to non-soldering problem , Dipping the lens into the solder must be avoided.

Do not apply any external stress to the lead frame during soldering while the LED is at high temperature.

Recommended soldering conditions :

Note: Excessive soldering temperature and/or time might result in deformation of the LED lens or

catastrophic failure of the LED. IR reflow is not suitable process for through hole type LED lamp

product.
