1. Summary

To make the best use of WORLDSEMI’s LED, please refer to the below precautions, they are of same usage

method as other electronic components.

2. Cautions

2.1. Dust & Cleaning

The surface of the LED is encapsulated with modified epoxy resin because it plays a very good role in protecting

the optical performance and aging resistance. The modified epoxy resin is easy to stick with dust and must be kept

clean. When there’s a certain amount of dust on the surface of the LED, it won’t affect brightness, but dust proof

should be taken care of. Promoting the use of unsealed package in preference to others and the assembled LEDs

should be placed in a clean container.

Avoid using the organic solvents to clean the dust on the LED surface and it’s necessary to confirm whether the

cleaning fluid will dissolve the LED.

Do not clean the LEDs by the ultrasonic. Some parameters affecting the LED performance must be evaluated if

have no alternative but to the ultrasonic cleaning method, such as ultrasonic power, baking time and assembly

conditions, etc.

2.2. Moisture-proof packaging

TOP SMD LEDs are moisture sensitive components. LEDs are packaged in aluminum foil bag to prevent the

from absorbing moisture during transport and storage. A desiccant is placed in the bags to absorb moisture. If the

LED absorbs moisture, then it evaporates and expands when in reflow process, which may break the colloid from

the bracket and damage the optical performance of LED. For this reason, moisture-proof packaging is to prevent the

from absorbing moisture during transport and storage. The moisture resistance rating of WORLDSEMI’s LED is:
