Figure 18. Solder stencil aperture.
1.2 Recommended Metal Solder
Stencil Aperture
It is recommended that only a
0.152 mm (0.006 inch) or a
0.127 mm (0.005 inch) 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 3.05 mm x 1.1 mm as per land
pattern.

1.3 Adjacent Land Keepout and
Solder Mask Areas
Adjacent land keepout is the
maximum space occupied by
the unit relative to the land
pattern. There should be no other
SMD components within this
area.
The minimum solder resist strip
width required to avoid solder
bridging adjacent pads is 0.2
mm.
It is recommended that two
fiducial crosses be placed at mid-
length of the pads for unit
alignment.
Note: Wet/Liquid Photo-
Imageable solder resist/mask is
recommended.
