I am facing an issue in the routing of a footprint that I created in KiCAD. The design is for a pad; like, if it is pressed, then there is 1 at the output, just like the Push Button.
Now I have designed the footprint as spirals of two different nets, i.e., 1 and 2. I placed one pad for connection 1 and a second pad for connection 2.
The issue I have encountered is this:
A) I am unable to take any route from the pad of this custom footprint that I have created. If I try to take one, the pad becomes green and says âDRC Violation.â
B) When I take route from another component, i.e., a resistor in the picture it also fails to connect with the custom footprint.
What changes do I make in my footprint so that I am able to route this footprint in my main design. Images are attached for reference.
Do you have a Symbol that links to this footprint ? You connect to the symbol and that is how the footprint âknowsâ what nets it needs to connect to . . .
Yes, I have symbol associated with the footprint. The footprint also have pads labelled as 1 and 2. But the issue is that I am unable to take any route out of these both pads and also unable to connect any route taken from other component to this footprintâs pad.
The issue as far as i have noticed must be with the lines as the lines that I have drawn on top of them the pad is placed but these lines have no such characteristics i.e the pad number as the pad is just placed on top of the line. Here, I want to know that as I am unable to assign the net or number to the lines etc and arcs that I have drawn to make a circle like shape then how can i overcome this issue. Should i try making the shape of pad a straight line or circular or what should i do. I need suggestions on it.
Indeed.
Use the Pad Edit Mode as Piotr has already mentioned. The goal is to make these diagonal graphic lines a part of the pad themselves.
I also want to suggest that you start with something simpler. Maybe with just 4 or so diagonal lines. First make that work. Once you understand the principles, you can extend it to your more elaborate design.
In my experience, itâs always better to first learn the principles with simple dummy projects. In a more elaborate project, you spend a long time on the actual drawing, and youâre likely to make mistakes, and as a result you may have to do all that drawing again, or make heavy modifications. That a lot of duplicate work and boring.
This looks like a footprint for some rubberized button. If so, you probably also want to look into aperture pads, but that is a separate item.
I donât understand what BlackCoffe is attempting to show here with the âwoofâ tracks. Sure, you can assign net names to graphics in the PCB editor. But I think that designing a proper footprint in the Footprint Editor is a better approach here.
