In V5 to have arcs at copper layer I was making arcs at graphic layer and then changed their layer.
Is it possible in V7 to route arc track? If yes - how to get such track?
I have round ferryte and want to design laying at it round RFID antenna. I think of doing it as PCB design and not footprint design.
I remember that trying to do such things as footprint there were problems with vias and tracks at other then top layer.
I plan to have 3 coils each on separate layer of 4 layer PCB and EMI shield at bottom.
Hi, I donât know the answer to your question.
But as far as I know, when doing a footprint, you cannot add copper to the inner layers. The inner layers are disabled in the footprint editor.
I could be possible to do it by editing the layer of specific part inside the footprint file (manually with a text editor), But I donât think that it can be done via the footprint editor.
Is it possible in V7 to route arc track? If yes - how to get such track?
In principle yes.
- routing with corner-mode set to: â90 degree roundedâ. This places an 90°-arc at every track-bending. To change the corner-mode:
- hotkey âtrack corner modeâ
- or during routing: RMB-clickâ>context-menuâ>cycle corner mode
- all copper graphics can be converted to tracks and than subsequently can be assigned a netname:
- draw a arc/circle on the wanted layer
- this graphic element has the old problem of creating a DRC-error with all other standard tracks
- select the graphicâ>RMBâ>context menuâ>Create from selectionâ>Create Tracks from selection
- the original graphics remain selected, delete them
- select the new created tracksâ>doubleclickâ>assign a netname in the track properties dialog
regarding footprint and copper on inner layers: still not possible
What I remember there were some problems even with track at bottom (part of coil) connected by vias. Because of this I decided to not try to do that antenna as a footprint. I supposed (but not checked it) that using inner layers in footprint is also problematic.
Thanks.
This is probably the right way for me (I need something about 340 ⌠350 degree arcs).
Filleted Lines or Circle works similarly but, not identically the same.
I use the Circle approach to get cleaner Arc segment from Circleâs.
Creating a Track from a Circle or Arc creates a âHiddenâ Duplicated item.
The example below shows that I set the Line-width (to be able to visually differentiate the two lines) then, I delete the Graphic and Double-Click the âCreated Trackâ and set itâs width and NET (and delete the graphic).
I think it is about this:
I have changed plans and I am doing something else so didnât checked myself how it works. I have only written in my KiCad cheat sheet the information I got to have it at hand.
