Solder Pad dimensions for component with castellated mounting holes

[sdim]

Hi!

I want to use a component that has castellated mounting holes.

The component has 1.27mm pitch (0.01 inch) and each pad is 0.84 x 1.22 (including the semi-circle cut).

The design should be good for both hand soldering and for reflow soldering.

Are there any design guidelines for the solder pads dimensions (widgh, height,padding, etc)?
