This video is a part of KiCad 7 tutorial series, Which will take you through the journey of learning KiCad 7 from scratch to making your first Printed Circuit Board.
In this particular video, We'll discuss how to use route track tool of KiCad and try to route all the footprints. Also, try to understand basics design principle of routing using some example. Then will discuss how to switch layer using top and bottom copper layer along with via and pads. Finally the video ends with copper filling and verifying the PCB in the 3d viewer.

After creating the "COPPER FILL ZONE" with the polygon tool, he left out the fact in the video that you have to either right click, then select "Fill zone" or use the short cut "B" to initiate the copper fill. Its mention a few time below, figured better to have it up top. Otherwise, nice tutorial!!!
Thank you!
I spent 2 days trying to figure out why I was getting a fill until I stumbled onto the B fill command. He forgot that detail. Works fine now.
Hello sir, I'm a high school teacher from the Czech Republic and I teach KiCad, I know the basics but this series is a great extension for me, thanks a lot!
Glad you like the series! Thanks for the kind words.
My name is elson and I am a brasilian. Also am studying Kicad.
Very useful series of videos. I've designed at lot of PCBs, but not with KiCad, so I found this description of the features helpful.
The commercial package I am most familiar with had two very useful features that KiCad does not seem to.
The first was that when routing a track, one keystroke would place a via at the current point and flip to the 'other' layer and then continue routing on that other layer (with multilayer boards you could define a pair of layers to do this with). Very useful to be able to flip from side to side quickly when going across a board. With KiCad, as far as I can see you need to stop routing, place a via, select another layer, then start routing again from that point. Same effect, but the other package managed it with one keystroke. Maybe some sort of macro or python script could be created to do that, don't know.
The second was related, in that one might have a track, and realise later that a segment of it needed to be flipped to the other side - layout tends to be an iterative process. Again all one had to do was select the segment, and one keystroke would again flip the side, and place vias at each end. Or, if the result of the flip was that a via wasn't needed, remove it if there was one (such as if you flipped the track back to the first side again). Again, no doubt KiCad can do it with more actions (add/remove vias, delete segment, select other layer, route segment again etc), but the single keystroke was quick and easy. Again, maybe some script could do it, don't know.
Learned more about how to use vias and give a radius to traces. Neat.
Glad it was helpful!
Nice video, well done,thanks for sharing it with us :)
Your welcome!🙌
I was curious about the 90° vs 45° vs Arc section and it seems that these days it's not a problem for the vast majority of PCBs. It seemed to be a bigger problem in the past and these days only for some high frequencies (I've heard MHz and GHz range). So I think 90° angles should be ok and 45° should work for pretty much everything just as well as arcs. I just thought I would share that here for anyone who's interested in this.
PS: Thanks for your tutorial, man. Been binch-watching your whole series. Good stuff!
Thanks for sharing the information! You are totally correct, 90 degrees should be okay when designing low speed PCBs. Glad you enjoy these videos!
Great, pls continue the series with many high speed routing
Once our beginners series is complete. we'll be moving on to more advanced topics.
Great videos!! Can you add the link to where is explained about the angles and reflections? The link that exists in the description of the video doesn't cover that, thanks!!!
This should help you! : www.raypcb.com/signal-reflection-in-pcbs/
I'm starting with this, but I was wondering...
Once you have the copper planes grounded, aren't those ground routings redundant?
Yes! They both merge together, just for the purpose of explaining the 'via' I have drawn the track for the ground.
Sir may I know why the track from R4 to MK1 and SW1 to U1 is not visible in pcb and remain isolated from copper fillings in footprint?
Track R4 to MK1 (Ground) and SW1 to U1 (Ground) are merged with copper fillings (Ground). You can see the final layout at 9:09
Great video as always! Im facing an issue with the copper fills setting as im unable to obtain a filled zone. Can anyone tell me why is that?
Solved it! I forgot to add the paste layer in the pcb lol!
Glad you could fix it.
Hello while I route the trace the trace is routing just in outline and not filled
Turn off the "show track in outline mode." You can toggle this with shortcut 'k'
is there a way to automatically set the minimum distance between placed components be 1.016 mm or should we do it manually by using ruler
The component size and shape can vary a lot, so there might be no automatic way to set the minimum distance.
But you can use "Positioning tools" to place them accurately apart from each other.
Select the footprint -> Right click -> Position Relative to (And on the pop up select the reference and the distance between them)
Alternatively you can also create custom Grid size under Grid settings with 1.016mm on both X and Y axis. This will not give a accurate minimum distance between the components, but this process will be much faster.
@@pcbcupid Thank you
Hello Sir, Very nice series !! I enjoy it ver much, and i am making a lot of progress now withe the good ecplanation. But now in this one I am stuck ! ! with the copper fill. How do I deselect the polygone after the filling... "enter" ? " Double click" ? or somthing else ? each time the copper fill disappears also ?? Help ! ! ! For the rest so far thank you very much
Glad it's helpful!
Just double click when you finish drawing the polygon.
Press "B" after you're finished outlinig and it will fill
Wasn't able to make copper layer to fill. I could build polygon around PCB -- but when I connect final end -- just had outline of polygon
Use the shortcut 'B' to build the copper pour layer.
@@pcbcupid Yeah you kinda missed mentioning that step in the video.
where did all you components on the PCB disappear to in your last 3D view?
can you please mention the timestamp?
I followed your steps to apply the copper field, but at the end when I go to 3D view, I can see that the copper field was not applied. Do you know why this is happening?
I found the solution. After making the polygon, I had to right click and then select "Fill All Zones" option.
Yes, sorry for not mentioning it. I have pinned it in the comment section.
after adding my field zone layer my PCB remained the same in the 3D viewer. No change
Did you try toggling on / off the visibility of different layers on 3d viewer?
the routing start point violates drc means??
There are multiple reason why this could happen
Trackwidth might be thicker than the pad (so it might affect the near by pads as well)
copper mininum clearance (Under design rules) too large for the pad-to-pad clearance.
If you like to share the issue with an image. Please post the image here : pcbcupid.com/add-question/
🎉
🙌🙌
Could you explain the copper fill a bit more?
Sorry for rushing on that topic.
There are many reasons why we should use copper fill
1. Easier to etch copper during manufacturing
2. Copper fill helps in heat dissipation
3. Copper Balance - By balancing the amount of copper on both sides of the board will reduce warping, which might occur during reflow
4. Connecting the copper fills to ground can help with noise reduction by adding shielding
5. High current paths - Provide a short return path for high current devices
@@pcbcupid Make a detail video about it.
I didn't catch what does copper fill do
Copper filling is a process where copper is used to fill in the gaps and spaces on a circuit board, improving its conductivity and etching process during production. Usually this excess copper is connected to ground for better electrical performance as well.
@@pcbcupid is the copper fill it's own layer of the PCB stack? I didn't see it as part of the layers. Also, which gaps are you referring to?
@@joshuamerullo3593 it's not a different layer, it's on the copper layer (both front & back). Once you route your PCB, there would be excess gap between the traces and between the components. This gap is filled with ground/copper fill.
