Description
NFSW172AT is WHITE LED. A white LED chip is a semiconductor device that emits white light when an electric current passes through it. Unlike traditional light sources such as incandescent bulbs or fluorescent lamps, which emit white light by generating heat or through gas excitation, white LEDs generate light through a process called electroluminescence.
1. This LED is designed to be reflow soldered on to a PCB. If dip soldered, Nichia cannot guarantee its reliability.
2. Reflow soldering must not be performed more than twice. Hand soldering must not be performed more than once.
3. Avoid rapid cooling. Ramp down the temperature gradually from the peak temperature.
4. Nitrogen reflow soldering is recommended. Air flow soldering conditions can cause optical degradation, caused by heat and/or atmosphere.
5. 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.
6. Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable,
