Observe necessary precautions of handling moisture-sensitive devices as stated in the following section. Do not apply any pressure or force on the LED during reflow and after reflow while 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 maximum – Soldering duration = 3 seconds maximum – Number of cycles = 1 only – Power of soldering iron = 50W maximum 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 before hand whether the functionality and performance of the LED is affected by soldering with hand soldering. Figure 15: Recommended Lead-Free Reflow Soldering Profile The encapsulation material of the LED is made of silicone for better product reliability. 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.     TEMPERATURE 10 to 30 SEC. 245 – 250°C 217°C 200°C 3°C/SEC. MAX.  6°C/SEC. MAX. 150°C 3°C/SEC. MAX. 100 SEC. MAX. 60 – 120 SEC. 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. For automated pick and place, Broadcom has tested a nozzle size with OD 1.5mm 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.

Refer to Broadcom Application Note AN5305, Handling of Moisture Sensitive Surface Mount Devices for additional details and a review of proper handling procedures. The soldering terminals of these Broadcom LEDs are silver plated. If the LEDs are exposed in an ambient environment for too long, the silver plating might be oxidized, thus affecting its solderability performance. As such, keep unused LEDs in a sealed MBB with desiccant or in a desiccator at
