I thought so to, but never had a problem with this -- I did start off by putting small "targets" (crosshairs) on the pattern, drilling small holes before etching and lining up the targets with these holes on both sides. However, I found that folding and actually making an envelope (credit to someone else on this list whose name escapes me, sorry) with 3 sides stapled together, works well. It helps to leave a lot of extra transparency overhanging off the PCB.

Hi 2 All It seems hopeless for me to do one side pcb, eagle didn't have success in one side auto route. so I have to move to two sided pcb. I've seen some discussions about double side methods but I am looking for the best way, folding transparency sheet look to me not to accurate, can anyone suggest other better ways? I am desperate!
