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 placement of the unit. The castellations will completely self-align to the pads during
solder reflow as seen in the pictures below.

reflow.
3.2. Tolerance for Rotational (Theta) Misalignment
Units when mounted should not be rotated more than
2 degrees with reference to center X-Y as specified
in Figure 2. Pictures 3 and 4 show units before and after reflow. Units with a Theta misalignment of more
than 2 degrees do not completely self-align after reflow. Units with
2 degree rotational or Theta
misalignment self-aligned completely after solder reflow.
Picture 3. Unit is rotated before reflow.
Picture 4. Unit self-aligns after reflow.
