* 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 Cathode 2 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.

* When using a pick and place machine, choose an appropriate nozzle for this product. Using a pick-and-place nozzle with a smaller

diameter than the size of the LED's emitting surface will cause damage to the emitting surface and may also cause the LED not

to illuminate.

* 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.
