I wasn’t sure where to tag this - maybe it should be in manufacturing?
Anyway, I’ve been reading some threads about making strange-shaped plated holes and am none-the-wiser, other than understanding that this isn’t a standard thing and is going to need input from the fab-house, which is fine. In advance of that, so I have something sensible to go to them with, can anyone help me make a start on a plated routed hole that’s this shape?:
So far I’ve create the shape in the silk-screen layer, and then edited the KiCAD file in a text editor to change the layer of that shape to the edge-cuts layer, and then placed a circular pad over the top of the routed area to provide the exposed copper pad around the edges, but I now realise that this won’t give me the plating on the hole that I need.
