3.3. Y-axis Misalignment of Castellation
In the Y-direction, the unit does not self-align after solder 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

3.4. Example of Good HSDL-3602-007/
-037 Castellation 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.
