I used a Graphtec vinyl cutter and about the best I could do was
standard 0.1" spacing DIP ICs in a psuedo-SMT way. No holes, leads
trimmed flush and soldered onto the copper side.
I also made some boards that I did drill, but without a guide hole
etched it was difficult to drill accurately.
No way could I have had a lead pass between pins or done narrow traces
with standard solder pads.
But very possibly accurate enough to make a solder paste stencil.
