Planar inductor in PCB
« on: September 24, 2018, 06:17:46 am »
Hi,
I want to keep the inductor Trace width and spacing to a fixed value, I do not know how to do it in altium, since all the tracks have the same net, do you have any Idea how to implement it?

Build it as a component, then bring it in as a part.  Albeit a part that is ony made up of copper on the board.

Set up a grid where the spacing is equal to your terrace width + space to make drawing the coil easier.  Use a net tie to prevent shorts between the ends of the coil.

Yes, make a footprint and assign it the Net Tie property.

The problem still remains, how to make a footprint! precisely :( making sure the trace and spacing remains the same.

For a square coil as you've shown, just set up the grid so that snapping to it will give you the correct center-center spacing of your turns.  Setting the trace width should be obvious.

For more challenging shapes you can use a more sophisticated drawing program to create the shape and then import this as a DWG.  You will probably still need to do some massaging.

Thanks for the tip ;)

I remember in the Old Altium someone make a plugin for that but it was spiral

Thanks, do you have the name of that plugin, or can you share it? :)
