Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

While I was out yesterday, I saw that there were basically 3 kinds of
spray starch available... regular, heavy, and a non-stiffening
sizing. I'm not yet set up to etch, or I'd try all 3 myself and
report back. Is there any kind of "test etch" pattern set up for
testing these things? Different trace widths or whatever?

Also, I've heard at least some transfer paper is covered
with "dextrin", a sugar. Just thought I'd pass that on...
