![]() ![]() That would explain why the parts appear to be mirrored, they are supposed to be that way on a two sided board. If you routed based on the other way your routing will be backwards. Fritzing parts library install#Īre you trying to install the parts as if they were on the top of the board (as would be the case with a two sided board?) If you install them as if they were on the bottom of a two sided board are they then correctly aligned? I’m not much of an expert in the pcb area, and I haven’t heard of anyone trying a single sided SMD pcb (although that doesn’t mean much), but that’s all that I see here that might explain this. ![]() However this circuit appears unlikely to work. Q4 for instance has no connection to the base. With nothing to drive it it won’t do anything. Q1 has no connection to the collector, while you may be using the base emitter junction as a diode, that seems unlikely. The 4081 both is not a fritzing part (there is one in current core parts) nor correct, it doesn’t have a ground and thus won’t work. I’d advise routing the schematic view of the board and make sure it is correct. That should put rats nest lines to the appropriate connections in pcb view. You need to delete all the traces in pcb view before doing this in schematic though, as conflicts can corrupt the sketch. ![]()
