In testing, Cree has found XLamp MK-R2 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 the solder paste used.
Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment.

Cree recommends keeping XLamp LEDs in the provided, resealable moisture-barrier packaging (MBP) until immediately prior to soldering.
Unopꢀnꢀd MBPs that contain XLamp LeDs do not nꢀꢀd spꢀcial storagꢀ for moisturꢀ sꢀnsitiꢁity.
Once the MBP is opened, XLamp MK-R2 LEDs may be stored as MSL 1 per JEDEC J-STD-033, meaning they have unlimited floor life in
conditions of ≤ 30 ºC/85% relative humidity (RH). Regardless of storage condition, Cree recommends sealing any unsoldered LEDs in the
original MBP.
