I have been asked to write a formal technical paper on Photoetching and
Etching techniques. I would very much appreciate any regarding
your sucesses, tips and failures regarding etching. I plan to cover PnP
Blue, Photocopy Transfer etching, direct laser copy process, ferric
chloride, ferric nitrate and nitric acid.
Thanks so much.
