So after having numerous alignment issue trying double sided DIY PCB, I decided to try single sided (bottom layer). Autorouter completes to 93%, I'm left with a few traces to connect manually so, I added pads close to the ratlines then tried to route them manually but this doesn't seem to work. Can this be done by adding pads or vias to complete the ratlines then using jumpers on top layer? or is there some other way to go about this? thanks
