■ Precautions for use:
1. Storage
To prevent moisture absorption into SMD LEDs during the transportation and storage , the LEDs are packed
in a moisture-barrier bag. Desiccants and a humidity indicator are packed together with the LEDs as
secondary protection
The shelf life of LEDs stored in the original sealed bag at <40℃ and < 90% RH is 12 months. Baking is
required if the shelf life has expired
Before opening the packaging , check for air leaks in the bag.
After the bag is opened, the SMD LEDs must be stored at <30℃ and < 60% RH. Under these conditions,
SMD LEDs must be used within 24 hours. If the LEDs are not within 24 hours after removal from the bag ,
baking is required Take the material out of the packaging bag before baking. Do not open the oven door
frequently during the baking process.
2. Soldering
(1) Manual soldering with a soldering Iron
Use a soldering iron of less than 25 watts is recommended . The iron temperature must be kept below 315℃
And soldering time no more than 2 seconds.
The epoxy resin of an SMD LED should not contact the tip of the soldering iron.
No mechanical stress should be exerted on the resin portion of an SMD LED during soldering.
Handling of an SMD LED should be done only when the package has been cooled down to below 40℃
(2)Reflow soldering
