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.
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.
