NS9W383 Datasheet, PDF (8/24 Pages) NICHIA CORPORATION – SPECIFICATIONS FOR WHITE LED

NICHIA STS-DA1-2717B <Cat.No.130726>
* Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable,
a hot plate should be used.
It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
* The Die Heat Sink should be soldered to customer PCB.
If it is difficult or impossible, use high heat-dissipating adhesive.
* When soldering, do not apply stress to the LED while the LED is hot.
* This LED can be soldered to a PCB designed for the recommended soldering pad pattern of Nichia’s 183series.
* The recommended soldering pad pattern is designed for attachment of the LED without problems.
When precise mounting accuracy is required, such as high-density mounting, ensure that the size and shape of the pad
are suitable for the circuit design.
* When flux is used, it should be a halogen free flux. Ensure that the manufacturing process is not designed in a manner
where the flux will come in contact with the LEDs.
* Make sure that there are no issues with the type and amount of solder that is being used.
