  Stencil 

The layout of the stencil apertures can be the same as the recommended footprint (1:1), 
we suggest a thickness of stencil foil 

≥

 120 µm. 

 

  Solder paste 

Item 

Lead Free 

Solder Paste 

Sn/Ag/Cu 

Table 23

: Solder paste 

We recommend using only “no clean” solder paste to avoid the cleaning of the modules 
after assembly. 

 

     Solder Reflow 

Recommended solder reflow profile: 

 

 

 

 

 

 

 

 

 

 

 

Figure 11: Recommended Solder reflow profile 
 

 

Warning: The  aforementioned  solder  reflow  profile  represents  the 
typical  SAC  reflow  limits  and  does  not  guarantee  the  adequate 
adherence of the module to the customer application throughout the 
temperature range. The customer must optimize the reflow profile 
based  on  the  overall  system  taking  into  account  factors  such  as 
thermal mass and warpage.
