As a general guideline, Cree recommends that users follow the recommended soldering profile provided by the manufacturer of the solder paste used. Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment. tP TP Critical Zone TL to TP Temperature Ramp-up TL tS Tsmax Tsmin Ramp-down ts Preheat 25 t 25˚C to Peak IPC/JEDEC J-STD-020C Time Profile Feature Average Ramp-Up Rate (Tsmax to Tp) Lead-Free Solder 1.2 °C/second Preheat: Temperature Min (Tsmin) 120 °C Preheat: Temperature Max (Tsmax) 170 °C Preheat: Time (tsmin to tsmax) Time Maintained Above: Temperature (TL) Time Maintained Above: Time (tL) Peak/Classification Temperature (Tp) 65-150 seconds 217 °C 45-90 seconds 235 - 245 °C Time Within 5 °C of Actual Peak Temperature (tp) 20-40 seconds Ramp-Down Rate 1 - 6 °C/second Time 25 °C to Peak Temperature 4 minutes max. Note: All temperatures refer to topside of the package, measured on the package body surface. Note: While the high reflow temperatures (above) have been approved, Cree’s best practice guideline for reflow is to use as low a temperature as possible during the reflow soldering process for these LEDs.

These measurements will change over time based on a number of factors that are not within Cree’s control and are not intended or provided as operational specifications for the products. Calculated values are provided for informational purposes only and are not intended as specifications. Pre‑Release Qualification Testing Please read the LED Reliability Overview for details of the qualification process Cree applies to ensure long-term reliability for XLamp LEDs and details of Cree’s pre-release qualification testing for XLamp LEDs. Lumen Maintenance Cree now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED lumen maintenance. For information on the specific LM-80 data sets available for this LED, refer to the public LM-80 results document. Please read the Long-Term Lumen Maintenance application note for more details on Cree’s lumen maintenance testing and forecasting. Please read the Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect the LED junction temperature. Moisture Sensitivity Cree recommends keeping XLamp ML-B LEDs in the provided, resealable moisture-barrier packaging (MBP) until immediately prior to soldering. Unopened MBPs that contain XLamp LEDs do not need special storage for moisture sensitivity. Once the MBP is opened, XLamp ML-B LEDs should be handled and Maximum Percent Relative Humidity stored as MSL 2a per JEDEC J-STD-033, meaning they have limited Temp. 30% 40% 50% 60% 70% 80% 90% exposure time before damage to the LED may occur during the soldering 35 ºC - - - 17 1 .5 .5 operation. The table on the right specifies the maximum exposure time 30 ºC - - - 28 1 1 1 in days depending on temperature and humidity conditions. LEDs with 25 ºC - - - - 2 1 1 exposure time longer than the specified maximums must be baked 20 ºC - - - - 2 1 1 according to the baking conditions listed below. Baking Conditions It is not necessary to bake all XLamp ML-B LEDs. Only the LEDs that meet all of the following criteria must be baked: 1. LEDs that have been removed from the original MBP. 2. LEDs that have been exposed to a humid environment longer than listed in the Moisture Sensitivity section above. 3. LEDs that have not been soldered. Copyright © 2010-2016 Cree, Inc.

UL® and the UR logo are registered trademarks of UL LLC. 7 XLamp ® ML-B LED Notes - Continued LEDs should be baked at 70 ºC for 24 hours. LEDs may be baked on the original reels. Remove LEDs from the MBP before baking. Do not bake parts at temperatures higher than 70 ºC. This baking operation resets the exposure time as defined in the Moisture Sensitivity section above. Storage Conditions XLamp ML-B LEDs that have been removed from the original MBP but not soldered should be stored in one of the following ways: • Store the parts in a rigid metal container with a tight-fitting lid. Verify that the storage temperature is <30 °C, and place fresh desiccant and an RH indicator in the container to verify that the RH is no greater than 60%. • Store the parts in a dry, nitrogen-purged cabinet or container that actively maintains the temperature at <30° and the RH at no greater than 60%. • For short-term store only: LEDs can be resealed in the original MBP soon after opening. Fresh desiccant may be needed. Use the included humidity indicator card to verify <60% RH. If an environment of <60% RH is not available for storage, XLamp ML-B LEDs should be baked (described above) before reflow soldering. RoHS Compliance The levels of RoHS restricted materials in this product are below the maximum concentration values (also referred to as the threshold limits) permitted for such substances, or are used in an exempted application, in accordance with EU Directive 2011/65/EC (RoHS2), as implemented January 2, 2013. RoHS Declarations for this product can be obtained from your Cree representative or from the Product Documentation sections of of www.cree.com. REACh Compliance REACh substances of very high concern (SVHCs) information is available for this product. Since the European Chemical Agency (ECHA) has published notice of their intent to frequently revise the SVHC listing for the foreseeable future, please contact a Cree representative to insure you get the most up-to-date REACh SVHC Declaration. REACh banned substance information (REACh Article 67) is also available upon request. UL® Recognized Component Level 4 enclosure consideration. The LED package or a portion thereof has been investigated as a fire and electrical enclosure per ANSI/ UL 8750. Vision Advisory WARNING. Do not look at exposed LED lamps in operation. Eye injury can result. For more information about LEDs and eye safety, please refer to the LED Eye Safety application note. Copyright © 2010-2016 Cree, Inc. All rights reserved.
