1.2 Adjacent Land Keep-out
and Solder Mask Areas
2.0 Recommended Solder
Paste/cream Volume for
Castellation Joints
Based on calculation and
experiment, the printed solder
paste volume required per
castellation pad is 0.28 cubic
mm (based on either no-clean or
aqueous solder cream types with
typically 60 to 65% solid content
by volume).
Dim.
Adjacent land keep-out is the
maximum space occupied by
the unit relative to the land
pattern. There should be no
other SMD components within
this area.
“h” is the minimum solder
resist strip width required to
avoid solder bridging adjacent
pads.
It is recommended that 2
fiducial cross be placed at mid-
length of the pads for unit
alignment.
