Subject: Re: Small Quntities of Dry Film Resist

Sorry, I forgot to mention that. It is 12 inches wide. I bought it
from think tink, so you can go to their site for information on how to
apply it. There are plenty of other sites as well. I am just getting
started with this as well.

For initial tests I will just use a flourescent light as my UV source.
I will also need to get some washing soda(sodium carbonate) to develop
the resist and sodium hydroxide to strip off the exposed resist.

If you go to a pool supply, do not get sodium hydrogen carbonate,
which is sodium bicarbonate. I did that on Friday, only to discover it
is not what I want. I will still keep it because it is good to have to
clean up acid spills or if I want to bake a cake. :)

After the initial tests I will probably build a UV LED exposure box
like Markus Zingg for my real board work. You can read his posts for
more information.
