>Derek - what are you using as a phototool >to get good 6/6 ? Epson R320 and Epson transparencies. I have two HP lasers here and used them until the dimensional inaccuracies started to get in the way of CNC drilling. Actually used laser transparencies instead of vellum so was up to my neck with pinhole correction and solvent fumigation tricks. My exposure box consists of normal daylight fluorescent instead of UV tubes since it had to double as a standard light box for pinhole correction. --- In Homebrew_PCBs@yahoogroups.com, "Andrew" <andrewm1973@...> wrote: >
