Figure 10 - FT232R Solder Reflow Profile
The recommended values for the solder reflow profile are detailed in Table 4. Values are shown for both a completely
Pb free solder process (i.e. the FT232R is used with Pb free solder), and for a non-Pb free solder process (i.e. the
FT232R is used with non-Pb free solder).

The FT232R is supplied in Pb free 28 LD SSOP and QFN-32 packages. The recommended solder reflow profile for
both package options is shown in Figure 10.
