Anyone designed a transformer( planar before? not sure how to start

So i need to design a planar transformer i did more or less the math but i am not sure how to define the PCB. make it a footprint? make it a trace and be careful not to let cad optimise trace length ?

Make it a footprint.https://resources.altium.com/p/how-create-planar-transformer-pcb-layout

i want to do it in kicad but ill see if i can aply it there

I cannot help you with KiCad, nor with other elements of transformers, but still I would make a footprint. It allows easier re-use.

i was considering makeing the magnetic core a footprint

in kicad i cant have specific internal layers for my footprint

IF i use a footprint design type then it need to make it 2L and stak tons on each other and have it really thin

What? Doesn't KiCad allow you to draw on internal layers in a footprint?Or is it comparable to Altium in that a footprint library also has a stack-up and that you need to define a 4 or higher layer count first?

it is like altium simple stack up , the one where all internal layers are replesented as 1

What a crap tool. It is not as if you are the first to ask.https://forum.kicad.info/t/footprint-in-inner-layers/1542/7https://forum.kicad.info/t/footprints-pads-on-internal-layers/11214/14

i think ill try with traces for now or lines +arcs so that i am optimisation free

still doing winding + core saturation math
