XLamp ML family LeD case temperature (T
s
) should be measured on the PCB surface, as close to the LeD’s thermal pad as possible. This
measurement point is shown in the picture below.
It is not required to use a solder footprint for the thermal pad that is larger than the XLamp ML LeD itself. In testing, Cree has found such
a solder pad to have insignificant impact on the resulting T
s
measurement.

XLamp ML family LEDs are designed to be reflow soldered to a PCB. Reflow soldering may be done by a reflow oven or by placing the
PCB on a hotplate and following the reflow soldering profile listed in the XLamp ML Family LED Reflow Soldering Characteristics section
(page 7).
Do not wave-solder XLamp ML family LeDs. Do not hand-solder XLamp ML family LeDs. N
