I’m routing a board with 2 layers. I placed a through hole 2 x 3 connector and a USON-20 on bottom place. But I failed to connect their pads. I’m using V4.0.7, since this version is default on my OS (Manjaro Linux).
When I use the trace for bottom layer, connection is not made. Surprisingly, the pads are connected when I use front side trace(red one). From footprint info window, I clearly see that the USON component is on bottom layer. But it seems PCBNew assume it’s on front plane.
