Top SMD LED Using Instructions
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: LEVEL 6.
