KEEP LESS THAN 30s WITHIN 5°C OF PEAK TEMP.
Due to the low mount height of the QFN, "No Clean" Type 3 solder
paste, per ANSI/J-STD-005, is recommended. Nitrogen purge is
also recommended during reflow. A system board reflow profile
depends on the thermal mass of the entire populated board, so it
is not practical to define a specific soldering profile just for the
QFN. The profile given in Figure 41 is provided as a guideline to
customize for varying manufacturing practices and applications.
