Re: Create copper layer tracks from an external image?
If you're planning to get the board made by a PCB house, don't forget to add pads so you get the drill holes! By coincidence, Michael Dranfield released this video a few days ago of him doing the same

Re: Create copper layer tracks from an external image?
Hi Chris, sure you can make the original pcb with KiCad. You can scan the original pcb and then process it with a graphics program to obtain a black and white or grayscale image. Then, you can use

Why not just try it? It wouldn't be the end of civilization if it failed. ====================================================================================== Best wishes John Woodgate OOO-Own

Re: Automatic disposition of thermal vias
Good evening John, thank you for sharing your experience with us. Ok, I'll try to make some appropriate screenshots. @Robert: Is there a way to send you private messages? In fairness, I'd prefer not

Re: Automatic disposition of thermal vias
Ciao, Alessandro. Thanks for the kind words. Yes, if you choose your screenshots carefully, so as not to miss any important data, that should enable Robert to help you.

Re: Automatic disposition of thermal vias
Good evening John, first of all thanks for the suggestion. I was thinking that I could make some screenshots of some pcb portions for Robert, in order to make my problem understandable to him. In your

Re: Automatic disposition of thermal vias
A PCB with no component references or other text is not likely to be commercially sensitive. You could ask your manager if you can send it only to Robert in order to get help with your project. If it

Re: Automatic disposition of thermal vias
Hi Robert. Thanks for your answer. The problem is at the very beginning of the procedure. First of all I have to create different sectors of the circumference: some contain only the two halves of two

Re: Automatic disposition of thermal vias
When you tried my suggestion (creating a component), did you create a matching part in the schematic, with all the "vias" (ie pins) connected to the relevant net(s)? That way you don't need to edit

Re: Automatic disposition of thermal vias
Hello everyone and thanks for your contribution. I have tried the proposed solutions but, at the moment, without success. I'm looking for some tricks to fix this kind of problem which, in the future,

Re: Automatic disposition of thermal vias
Hi Robert and Brian, thanks for your answer. I think i will try your solution in the next days. The only doubt concerns the fact that i've already tried to create circual array of thermal vias, and
Re: Automatic disposition of thermal vias
Perhaps the way to do this is to create a footprint with pattern required? With a footprint, you can create a through-hole pad that matches your thermal via requirements, and then right-click on the

Re: Automatic disposition of thermal vias
This is probably not the best approach but you might consider making a PCB footprint containing an arc of, say, 15 degrees with the required number of vias, place that, duplicate, rotate the duplicate

Re: Automatic disposition of thermal vias
Hi Jean Paul and John First of all thanks for your answers. Yes, the vias must be arranged in the shape of a circle, because the pcb has the shape of an annulus. In the printed circuit there are some

Re: Automatic disposition of thermal vias
It might be easier to make the array of vias in the shape of a hexagon or octagon. ====================================================================================== Best wishes John Woodgate

Re: Automatic disposition of thermal vias
Hello and welcome Alexandro, Like you, I use a translator and I'm not sure I understood correctly: do your vias have to be placed obligatorily in the shape of a circle? Otherwise, you can create an

Hello, Alessandro. Google has made your message clear. I do not know the answer to your question, but I am sure that someone else does know it.
