The last board I did, I only gave the copper a good scratch with some
old sandpaper. Seemed to work quite well: I'm a long way from being
certain, but I am working up to the belief that the toner needs a
rough surface to get a grip on more than it needs a whole lot of
solvents thrown at the copper. If I ever get certain, I'll sing out
but I thought I'd share.
