the smd you mention would work if you reduce the padsize in the software.
Right now 10mil is the closest reliable spacing i can make before it
bridges from toner spreading (however this will get better if i used less
than darkest toner, must experiment more).
6.66mil is the smallest track i can etch without underetching causing
trouble. So i would set the pad to 6.66mil, which widens slightly from
spreading anyway, and have more than 10mil spacing left. I would expect it
to work.
Toner transfer was the really exciting thing, this merely makes the
process much easier. However i'm glad i had the stupid idea to smear some
silicone on a sheet of paper with a floppy disc...
