3.3. Y-axis Misalignment of Castellation
In the Y-direction, the unit does not self-align after sol-
der reflow. It is recommended that the unit be placed
in line with the fiducial mark (mid-length of land pad).
This will enable sufficient land length (minimum of 1/2
land length) to form a good joint. See Figure 5.

Solder Joints
This joint is formed when the printed solder paste
volume is adequate, i.e., 0.30 cubic mm and reflowed
properly. It should be reflowed in IR Hot-air convection
reflow oven. Direction of board travel does not matter.
