Are 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. If you routed based on the other way your routing will be backwards. That would explain why the parts appear to be mirrored, they are supposed to be that way on a two sided board. A check of Q4 (comparing it to one installed on a two sided board in another window) indicates that is what the alignment here is. On a two sided board that means the smd part is flipped so it would be correctly aligned if installed on the bottom of the board (rather than the top of a two sided board as is standard). What I think may be your problem is the parts are showing as bottom layer. You have a top layer silkscreen (which likely isn’t what you want on a single sided board), although that isn’t likely your problem. The gerbers look fine, but I see a few things. ![]()
