Figure 9: Reflow Soldering Thermal Profile 

It  is  suggested  that  the  peak  reflow  temperature  is  from  235  to  245ºC  (for  SnAg3.0Cu0.5  alloy).  The 

absolute  maximum  reflow  temperature  is  260ºC.  To  avoid  damage  to  the  module  caused  by  repeated 

heating,  it  is  suggested  that  the  module  should  be  mounted  after  reflow  soldering  for  the  other  side of 

PCB has been completed. Recommended reflow soldering thermal profile is shown below:
