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.
Note:
Wet/Liquid Photo-Imaginable solder resist/mask is recommended.

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 0.30 cubic
mm
(based on either no-clean or
aqueous solder cream types with
typically 60 to 65% solid content
by volume).
