ASMY-CWG0-NX7D2

Data Sheet ASMY-CWG0-Nxxx2 Low Power 2216 DFN2 Surface Mount LED Overview Features The Broadcom® ASMY-CWG0 surface mount LEDs use InGaN chip technology with superior package design to enable them to produce higher light output with better intensity performance. They are able to dissipate the heat more efficiently resulting in better performance with higher reliability.  To facilitate easy pick and place assembly, the LEDs are packed in tape and reel. Every reel is shipped in single intensity and color bin, to provide close uniformity.    High reliability package with enhanced silicone resin encapsulation Available in 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K 6200K, 6500K, and 8000K CCT only Wide viewing angle at 120° Low package profile and large emitting area for better uniformity in linear lighting Applications    Indicators Electronic signs and displays – Channel lettering – Contour lighting – Indoor variable message sign Office automations, home appliances, industrial equipment – Front panel backlighting – Push button backlighting – Display backlighting – Keypad backlighting – Symbol backlighting – Scanner lighting CAUTION! This LED is ESD sensitive. Please observe appropriate precautions during handling and processing. Refer to application note AN-1142 for additional detail.

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 21: Recommended Lead-Free Reflow Soldering Profile 10 to 30 SEC.

Refer to Broadcom Application Note AN5305, Handling of Moisture Sensitive Surface Mount Devices for additional details and a review of proper handling procedures. REFLOW DIRECTION  Handling Precautions 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.      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.
