It is crucial for the end product to be designed in a manner that minimizes the thermal resistance from the solder point to ambient in order to optimize lamp life and optical characteristics. 200 180 Maximum Current (mA) 160 140 120 100 80 Rj-a = 30°C/W 60 Rj-a = 40°C/W 40 Rj-a = 50°C/W 20 Rj-a = 60°C/W 0 0 25 50 75 100 125 150 Ambient Temperature (ºC) TYPICAL SPATIAL DISTRIBUTION 120 Relative Luminous Intensity (%) 100 80 60 40 20 0 -90 -70 -50 -30 -10 10 30 50 70 90 Angle (º) Copyright © 2010 Cree, Inc.

As a general guideline, Cree recommends that users follow the recommended soldering profile provided by the manufacturer of solder paste used. Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment. Profile Feature Lead-Based Solder Lead-Free Solder 3°C/second max. 3°C/second max. Preheat: Temperature Min (Tsmin) 100°C 150°C Preheat: Temperature Max (Tsmax) 150°C 200°C 60-120 seconds 60-180 seconds 183°C 217°C 60-150 seconds 60-150 seconds 215°C 260°C 10-30 seconds 20-40 seconds 6°C/second max. 6°C/second max 6 minutes max. 8 minutes max. Average Ramp-Up Rate (Tsmax to Tp) Preheat: Time (tsmin to tsmax) Time Maintained Above: Temperature (TL) Time Maintained Above: Time (tL) Peak/Classification Temperature (Tp) Time Within 5°C of Actual Peak Temperature (tp) Ramp-Down Rate Time 25°C to Peak Temperature 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.

Please read the XLamp Long-Term Lumen Maintenance application note for more details on Cree’s lumen maintenance testing and forecasting. Please read the XLamp Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect the LED junction temperature. * These lifetime ratings are based on the current ENERGY STAR Solid State Lighting Luminaires V1.1 (December 12, 2008) and ENERGY STAR Integral LED Lamps V1.0 (December 3, 2009) lumen maintenance criteria. Moisture Sensitivity In testing, Cree has found XLamp ML-B LEDs to have unlimited floor life in conditions ≤30ºC / 85% relative humidity (RH). Moisture testing included a 168 hour soak at 85ºC / 85% RH followed by 3 reflow cycles, with visual and electrical inspections at each stage. RoHS Compliance The levels of environmentally sensitive, persistent biologically toxic (PBT), persistent organic pollutants (POP), or otherwise 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 2002/95/ EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS), as amended through April 21, 2006. Vision Advisory Claim Users should be cautioned not to stare at the light of this LED product. The bright light can damage the eye. Copyright © 2010 Cree, Inc. All rights reserved.
