  * This LED is designed to be reflow soldered on to a PCB. If dip soldered, Nichia cannot guarantee its reliability. 
  * Reflow soldering must not be performed more than twice. Hand soldering must not be performed more than once. 
  * 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. 
  * Since the silicone used in the encapsulating resin is soft, do not press on the encapsulant resin. 
      Pressure can cause nicks, chip-outs, encapsulant delamination and deformation, and wire breaks, decreasing reliability. 
  * Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable, 
      a double-head soldering iron should be used.   
      It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing. 
  * When soldering, do not apply stress to the LED while the LED is hot.
