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
land length.) to form a good joint. See Fig 5.0.
3.4 Example of Good HSDL-3612-007/-037 Castella-
tion 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.
