SMT Assembly Application Note
Solder Pad, Mask, and Metal Stencil
Recommended Metal Solder
Stencil Aperture
It is recommended that only a 0.127
mm (0.005 inches) or a 0.11 mm (0.004
inches) thick stencil be used for solder
paste printing. This is to ensure
adequate printed solder paste volume
and no shorting. See the table below
the drawing for combinations of metal
stencil aperture and metal stencil
thickness that should be used.
Aperture opening for shield pad is 2.7
mm x 1.25 mm as per land pattern.
