I need to make a footprint for a “swich” like these …
mine should have space for a LED, in the middle, too… on the silicon-button-mat that comes on top of the switch, is a velostat, so I can measure, the pressure on the pads.
my problem is, that I don’t get it, how I would build this golden, conductive rings … I tried with SMD-Pads
but this somehow seems not correct.
does someone have a idea how I could build this?
Your footprint would work from its layout but is not as pretty as the one in your picture. The one in the picture will either need a lot of work in the footprint editor, a bit of scripting or you could even use freecad and kicad stepup to create them.
However your footprint has a major flaws. The pad numbers of overlapping pads (the ones that need to be connected) must be equal. The reason for this is: How does KiCad know which symbol pin represents which pad of the footprint?
THANKS BRO !!! this might solve my problem… i alredy am making a new one right now
Also look at the pad with number 1. I assume it should not be connected to both the lower and upper half of the button.
yes, you are right… pad-1 is wrong, thank
one more question… can I place the drill-pads over the smd-pads?
yes. but they also need the same pin number as the smd pad they are on top of.
cool, thank you … you might have solved all my problems
I have made a new footprint now, but there are some more questions:
#1 … i have placed the smd-lanes overlapping, so they connect… but when I am using autorouter on the pcb-design, it connects the smd-lanes ( with the same pin-number) to each other…
also when i press “violations”, the points where the smd-lanes overlap are marked
do I have to place them not overlapping? …
#2 … I have 16 of them on my pcb and 16x rgb-LEDs and some pin connectors, nothing else…
the autoroute took 24 hours now, and has made 10 Passes… I canceled autoroute at this point?
how many passes are normal? … can I only make, lets say one pass? where do I configure this?
