characteristics
In testing, Cree has found XLamp mL-B 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 profle provided by the
manufacturer of solder paste used.
Note that this general guideline may not apply to all PCB designs and confgurations of refow soldering equipment.

Note: All temperatures refer to topside of the package, measured on the package body surface.
Note: While the high refow temperatures (above) have been approved, Cree’s best practice guideline for refow is to use
as low a temperature as possible during the refow soldering process for these LEDs.
