THERMAL DESIGN
The maximum forward current is determined by the thermal resistance between the LED junction and ambient. 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.

REFLOW SOLDERING CHARACTERISTICS
In testing, Cree has found XLamp ML-E LEDs to be compatible with JEDEC J-STD-020C, using the parameters listed below. 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 Average Ramp-Up Rate (Tsmax to Tp) Preheat: Temperature Min (Tsmin) Preheat: Temperature Max (Tsmax) 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
Lead-Based Solder 3°C/second max. 100°C 150°C 60-120 seconds 183°C 60-150 seconds 215°C 10-30 seconds 6°C/second max. 6 minutes max.
Lead-Free Solder 3°C/second max. 150°C 200°C 60-180 seconds 217°C 60-150 seconds 260°C 20-40 seconds 6°C/second max 8 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.

NOTES Moisture Sensitivity
In testing, Cree has found XLamp ML-E 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.
