Full Paste Mask on Pad

Hi folks! I've made a footprint for header castellations and I'd like to make sure there's no solder paste put on the top pad: ![Screen Shot 2022-04-02 at 3.25.19 PM.png](//image.easyeda.com/pullimage/2WmAADG0LbzZk9RHhKHKaI08DsRym4e8LuLfJOX1.png) How do I do that in the EasyEda footprint editor?

For each single layer pad in the structure, if you set a **negative** Paste Mask Expansion of more than half the smallest pad dimension then the aperture will close. Multi-layer (through-hole) pads do not have paste mask apertures anyway for obvious reasons. [https://docs.easyeda.com/en/PCB/PCB-Tools/index.html#Pad](https://docs.easyeda.com/en/PCB/PCB-Tools/index.html#Pad)<br> <br> Export the Gerbers and the Stencil file to check the results.

Oh, you only need to do that for the top layer pad... :)
