3.1 Tolerance for X-axis
Alignment of Castellation
Misalignment of castellation to
the land pad should not exceed
0.2 mm or approximately half the
width of the castellation during
Photo 1.0. Castellation misaligned to land pads in x-axis
before reflow.
3.2 Tolerance for Rotational
(Theta) Misalignment
Units when mounted should not
be rotated more than
with reference to center X-Y as
specified in Fig 2.0. Pictures 3.0
and 4.0 show units before and

placement of the unit. The
castellations will completely self-
align to the pads during solder
reflow as seen in the pictures
below.
after reflow. Units with a Theta
misalignment of more than 2
degrees do not completely self
align after reflow. Units with
degree rotational or Theta
misalignment self-aligned
completely after solder reflow.
Photo 4.0. Unit self-aligns after reflow.
Photo 2.0. Castellation self-align to land pads after
reflow.
