Hello, I am new to kicad and I can’t find how to do this:
Imagine I have a board with 2 resistors, they need to be connected in series, in the footprint I want to allow 2 valid places the resistor can be soldered (for example to make the board reversible, but for this example, I will show a single side)
so, here is the schematic:
I made it very simple, 2 resistors in series, but I created a custom footprint for the resistor:
notice that this is the footprint for a single resistor, but it can be soldered in one of 2 places: place A and place B, I don’t care.
then, is time to create the PCB, so here is what I have:
I connect the 2 resistors with a track…
but, I still have some ratsnest wires not connected, of course, since each resistor can be soldered in different places, I need to make sure those places are also connected, here I do it for the left one:
now, Imagine I need to replicate the same footprint hundreds of times, I quickly notice that I do not want to make the tracks inside the footprints, because is time consuming and error prone (maybe I forgot to do it in one of the footprints)
I need to find a way to add tracks to the footprint so when placed on a PCB those connections are done.
Since is not possible add tracks on a footprint, my solution is to draw them in the copper layer using lines in the footprint, like this:
then, I update my footprint in the PCB and this is what I get:
Notice how on the resistor footprint on the right kicad still shows ratsnests wires for unconnected pads even when there is a clear track of copper between them.
I understand the software limitation since those “tracks” are actually just a graphic line and not part of a pad, but how can I solve this?
How can I add tracks inside a footprint in order to connect repeated pads?, thank you very much
