STENCIL DESIGN



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 best results.



Evaluations have shown that the best overall

performance is achieved using the stencil

design shown in following figure. This design

for a stencil thickness of 0.127mm (0.005”).

The reduction should be adjusted for stencils

of other thicknesses.
