Figure 7-9 FT51A Solder Reflow Profile  
The recommended values for the solder reflow profile are detailed in Error! Reference source not  
found.. Values are shown for both a completely Pb free solder process (i.e. the FT51A is used with Pb  
free solder), and for a non-Pb free solder process (i.e. the FT51A is used with non-Pb free solder).
