Hi All,

Tony Nixon recently posted a URL to his own page on making PCBs

http://www.picnpoke.com/projects/pcb.html

I have always had mixed luck with etching my own PCBs but I tried Tony's
method and I want to say that it worked VERY well.

At first, I didn't think his method would work because I had tried ALMOST
exactly what he proposed in various forms before with only limited success
(the etching would take FOREVER, or some parts would etch completely and
begin to eat into the traces before the other part got started at all,
etc). I even tried bubble agtitation with uneven results. The KEY point
from Tony's method is to KEEP THE BOARD off the bottom of the container and
keep the face to be etched horizontal so that gravity can help keep fresh
etchant near the surface. No heating or bubbles necessary. I even etched a
double sided board by just flipping it over several times to give each side
time facing down. Each side etched very quickly (abt. 10 mins versus easily
40 mins before).

Thanks Tony!

Sean
