STENCIL DESIGN
* Contact International Rectifier to receive an electronic PCB Library file in your preferred format
Stencils for PQFN can be used with thicknesses
of 0.100‐0.250mm (0.004‐0.010"). Stencils thinner
than 0.100mm are unsuitable because they
deposit insufficient solder paste to make good
solder joints with the ground pad; high reductions
sometimes create similar problems. Stencils in
the range of 0.125mm‐0.200mm (0.005‐0.008"),
with suitable reductions, give the best results.

6A Highly Integrated SupIRBuck
Evaluations have shown that the best overall
performance is achieved using the stencil design
shown in following figure. This design is for
a stencil thickness of 0.127mm (0.005").
The reduction should be adjusted for stencils
of other thicknesses.
