* 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.

* 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.

* All of the electrode pads are on the backside of this product; solder connections will not be able to be seen nor confirmed

by a normal visual inspection. When using the product, ensure that there are no issues with the soldering conditions.
