KA Protection Device 4 SOLDERING • Reflow Soldering Condition(Lead-free Solder) 1 to 5°C per sec Pre-heat 180 to 200°C 60sec Max Above 220°C 120sec Max 260°CMax 10sec Max ● Recommended Soldering Pad Pattern R0.075 4.9 0.68 NICHIA STS-DA1-3118B ● Recommended Metal Solder Stencil Aperture R0.075 4.54 1.04 2.3 1.94 ( 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. * The reflow profile should be determined based on the recommended soldering conditions for the solder paste that is used. * 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. * This product uses glass on the emitting surface; if excessive force is applied, it may cause the glass to be damaged, chipped and/or deformed. If the glass is damaged, chipped and/or deformed, then the internal wires may be damaged and the reliability may decrease. Using a nozzle designed for the LEDs is recommended. (See the nozzle drawing below) Nozzle contact area: The center of the phosphor sheet. (See the second figure from the right) 2.6 1.6 R0.1 2.1 0.3 C0.1 ( Unit: mm) If the nozzle is off-center and makes contact with the edges of the phosphor sheet, it may cause the glass to be chipped and/or damaged. One example of this is shown in the first figure from the right. Ensure that there are no issues with the mounting conditions (e.g. mounting pressure, vacuuming pressure, etc.) prior to use. 5 NICHIA STS-DA1-3118B * 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. * W.
