•
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-
imagineable solder resist/mask is
recommended.
