Yes, it is. How did you drill the holes? The issue that always stops me from taking up toner transfer PCB fabrication is drilling the vias. I calculate that my typical 8" X 10" panel of boards is going to have about 1000 vias on it more or less. Even if I stack several boards, peg them together and drill them all at once, that's an awful lot of fine pitch holes to drill by hand. By the time I contemplate, design, and build some kind of automated hole drilling machine, I'm back to thinking that paying for fabrication is cheaper. Getting mil resolution on a mobile drill head is not a simple task, or so it appears to me. Then if I solved the drilling issue, or just buckled down and did it by hand, plating the through-holes either involves an intricate and slightly dangerous (and more importantly, takes up lots of space) copper electroplating capability or soldering a wire in every via, which is back to vast tedium. Grommets are too large for the vias I usually want and also are so expensive it's generally cheaper just to pay for fabrication. Anyway, solving the drilling and plating issue is what stops me from home PCB fabrication. Jeff Walther
