( Unit: mm). * This LED is designed to be reflow soldered on to a PCB. If dip soldered or hand soldered, Nichia cannot guarantee its reliability. * Reflow soldering must not be performed more than twice. * Avoid rapid cooling. Ramp down the temperature gradually from the peak temperature. * Nitrogen reflow soldering is recommended. Air flow soldering conditions can cause optical degradation, caused by heat and/or atmosphere. * Repairing should not be done after the LEDs have been soldered. 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.

4 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. * 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. 4.
