7. Cautions
7.1 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).
7.2 Storage
This product is qualified as Moisture sensitive Level 2a per JEDEC J-STD-020 Precaution when handing this
moisture sensitive product is important to ensure the reliability of the product.
The package is sealed:
The LEDs should be stored at 30°C or less and 90%RH or less. And the LEDs are limited to use within one year,
while the LEDs is packed in moisture-proof package with the desiccants inside.
The package is opened:
The storage ambient for the LEDs should not exceed 30°C temperature or 60% relative humidity. It is
recommended that LEDs out of their original packaging are IR-reflowed within 672hrs
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 a desiccators with nitrogen ambient.
LEDs stored out of their original packaging for more than 672hrs should be baked at about 60 deg C for at least 20
hours before solder assembly.
7.3 Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary.

Notes:
Because different board designs use different number and types of devices, solder pastes, reflow ovens, and circuit
boards, no single temperature profile works for all possible combinations.
However, you can successfully mount your packages to the PCB by following the proper guidelines and
PCB-specific characterization.
LITE-ON Runs both component-level verification using in-house KYRAMX98 reflow chambers and board-level
assembly.The results of this testing are verified through post-reflow reliability testing. Profiles used at LITE-ON are
based on JEDEC standards to ensure that all packages can be successfully and reliably surface mounted.
Figure on page3 shows a sample temperature profile compliant to JEDEC standards. You can use this example as
a generic target to set up your reflow process. You should adhere to the JEDEC profile limits as well as
specifications and recommendations from the solder paste manufacturer to avoid damaging the device and create
a reliable solder joint.
