One minor omission - mil eqiuvalents of the 0.1mm increments of drill sizes - don't know how common it is but PCAD shows drill sizes in mils if in imperial mode.
Yeah, had to leave something out in the end. Only had a mil->mm table.
Drill sizes are mostly done in mm anyway.
..and if you want a real luxury (expensive) version, on the other side have a matrix of all the different resist and silkscreen colours.
That would be nice. These were unfortunately a last minute rush job. Circuit Labs only had time to do a single sided run, and no gold plate, so it's only bare copper. Ideally I wanted metric one side, imperial the other etc.
The bigger wider 30cm rulers fit a lot more info and clearer text, but I liked the idea of compact 6" rule. Wider than a standard 6" rule though, so expanded to 7"
Should be very durable using Circuit Labs photo emulsion component overlay technique.
