Homebrew PCBs

This group sure looks like a good idea.

I have several interests. One is trying the CuCl etching method. See:

http://www.dnai.com/~rexa/Projects/CuCl_ech.html

for details. It looks cheap, and minimizes environmental impact. I am 
interested in hearing from anyone with related experience.

Another is trying to make prototypes with laser-printed PCB patterns 
more consistent. At present I use Dyna Art paper which I like. 

I haven't tried any other method, though, and am interested in 
inexpensive alternatives which work. For example, I read somewhere on 
the net that clay-coated 80 pound (I think) paper works well. I have 
been unable to find it at Staples here in Canada though apparently it 
is available in the US.

I also have some old silk screens with old PCB patterns. (Many are 
from early Elektor projects, though they are not labelled, so I am not 
sure what each one is. I plan to clean these screens and reclaim them, 
unless someone can help me identify the Elektor projects. In 
exchange I would try printing some of the patterns on PCB's. 

I think Javex does the trick to remove the old silkscreen stencil. I 
am interested in learning about how to apply new photoemulsion to the 
silk screen, and reproduce PCB art on the silk screen.

I use Ivex WinBoard. Does anyone know if there is a way to laser print 
the PCB pattern to mylar or the like (clear plastic), and use this to 
print to the photoemulsion.? Is there a computer method to turn a PCB 
pattern to a negative one, for laser printing? Is there a photemulsion 
which would respond to a laser printed positive on clear plastic, so 
a negative would not be required?

That's it for now. I look forward to seeing the group grow and pool 
knowledge and experience.
