2.4 Solder Reflow Profiles
The device is manufactured with Matte-Sn terminations and is compatible with both
standard eutectic and Pb-free solder reflow profiles. The recommended standard
eutectic reflow profile is shown in Figure 2-1. MSL qualification was performed
using the maximum Pb-free reflow profile shown in Figure 2-2.
