Hey DJ, I was just looking at your four layer boards and see that you said you used 13.5 mil vias. Do you mean you did plated thru holes? I just did a two layer board and thought the pins from each component would carry the solder from the trace on one side of the board to the trace on the other side. I was dearly mistaken. I re-layed out the board where I had vias away from any component just to carry the signal from one side of the board to the other. After drilling out the vias we simply put a piece of wire in the hole and soldered it on both sides of the board. How did you do the vias on your homemade board? They look so professional. My compliments! Thanks, Rob

The best material to work on was coated paper, usually the backside of old wall calendars (they were in price that time, but only those printed on one side!). The artwork was then copied to natural size negative by a huge camera. The minimum line width that time was about 0,5-0,6mm (20-24mils).
