Precautionary Notes      Do not perform reflow soldering more than twice. Observe necessary precautions of handling moisturesensitive device as stated in the following section. Do not apply any pressure or force on the LED during reflow and after reflow when the LED is still hot. Use reflow soldering to solder the LED. Use hand soldering only for rework if unavoidable, but it must be strictly controlled to following conditions: ─ Soldering iron tip temperature = 315°C max. ─ Soldering duration = 3sec max. ─ Number of cycles = 1 only ─ Power of soldering iron = 50W max. Do not touch the LED package body with the soldering iron except for the soldering terminals, as it may cause damage to the LED. Confirm beforehand whether the functionality and performance of the LED is affected by soldering with hand soldering. Broadcom Figure 13: Recommended Lead-Free Reflow Soldering Profile 10 to 30 SEC.

Compared to epoxy encapsulant, which is hard and brittle, silicone is softer and flexible. Observe special handling precautions during assembly of silicone encapsulated LED products. Failure to comply might lead to damage and premature failure of the LED. Refer to Broadcom Application Note AN5288, Silicone Encapsulation for LED: Advantages and Handling Precautions, for additional information.    Do not poke sharp objects into the silicone encapsulant. Sharp objects, such as tweezers or syringes, might apply excessive force or even pierce through the silicone and induce failures to the LED die or wire bond. Do not touch the silicone encapsulant. Uncontrolled force acting on the silicone encapsulant might result in excessive stress on the wire bond. Hold the LED only by the body. Do not stack assembled PCBs together. Use an appropriate rack to hold the PCBs.  Surface of silicone material attracts dust and dirt easier than epoxy due to its surface tackiness. To remove foreign particles on the surface of silicone, use a cotton bud with isopropyl alcohol (IPA). During cleaning, rub the surface gently without putting too much pressure on the silicone. Ultrasonic cleaning is not recommended.    Handling of Moisture-Sensitive Devices This product has a Moisture Sensitive Level 3 rating per JEDEC J-STD-020. Refer to Broadcom Application Note AN5305, Handling of Moisture Sensitive Surface Mount Devices for additional details and a review of proper handling procedures.   For automated pick and place, Broadcom has tested a nozzle size with OD 3.5mm to work with this LED. However, due to the possibility of variations in other parameters such as pick and place machine maker/model, and other settings of the machine, verify that the selected nozzle will not cause damage to the LED.  Broadcom The drive current of the LED must not exceed the maximum allowable limit across temperature as stated in the data sheet. Constant current driving is recommended to ensure consistent performance. Circuit design must cater to the whole range of forward voltage (VF) of the LEDs to ensure the intended drive current can always be achieved. The LED exhibits slightly different characteristics at different drive currents, which may result in a larger variation of performance (meaning: intensity, wavelength, and forward voltage). Set the application current as close as possible to the test current to minimize these variations. Do not use the LED in the vicinity of material with sulfur content or in environments of high gaseous sulfur compounds and corrosive elements. Examples of material that might contain sulfur are rubber gaskets, room- temperature vulcanizing (RTV) silicone rubber, rubber gloves, and so on. Prolonged exposure to such environments may affect the optical characteristics and product life. Avoid rapid change in ambient temperature, especially in high-humidity environments, because they cause condensation on the LED. If the LED is intended to be used in harsh or outdoor environment, protect the LED against damages caused by rain, water, dust, oil, corrosive gases, external mechanical stresses, and so on. Before use: ─ An unopened moisture barrier bag (MBB) can be stored at
