I have downloaded the NFC-antennas.zip from the 5th answer of this topic Where to find NFC Class 6 antenna PCB Schematic for KiCad
The import worked without problems, and I’m very grateful for the footprints. However the DRC throws errors when connecting them and I don’t know how to fix this. (KiCad 6.0.4)
The schematic only consists of the coil and one resistor connected to its terminals.
On the THT pads (“All copper layer” is selected in pad properties) but it does not let me connect two traces on the same layer like on Pad 2 in the picture. Pad 1 is ok since a bottom layer trace connects to a top layer trace. If I try to start routing from the pad it says “cannot start routing from a graphic”.
DRC says clearance error, but the Pad and the trace are the same net.
A workaround I found after some time for Pad 2 is to first connect a bottom layer trace and then manually change the layer of the trace to top.
But the DRC errors are still confusing me.
Some other discussions mention that maybe some graphics are drawn on the copper layer in the footprint and this causes problems. But what are the other options instead of drawing lines in the footprint editor and putting them on the F.Cu layer? Will it work if I send it to the fab with the workaround I used?
