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
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. Photos 3.0

placement of the unit. The
castellations will completely self-
align to the pads during solder
reflow as seen in the pictures
below.
and 4.0 show that unit cannot
be self-aligned back due to the
small wetting force. Units with a
Theta misalignment of more than
1 degree do not completely self
align after reflow.
