without resist. The quality was excellent (I have no connections with the
firm) and the price was about $25 per board. I could not have purchased the
equipment, spent the time nor come anywhere close to the quality of these
boards. I can't see how you can beat the quality and ease of use with any
homebrew method unless you plan to make bunches and bunches of boards

I don't create or build PCBs..I do design of boards and their artwork and
create the files (gerbers) needed to have the board made.

Thanks for info...not all boards come that cheap..I've done some 6-8 layers
and quite large and dense.
For the one time build, its the way to go. For those needing multi-layer and
quantity, thats a different story
Take care

My article will show you how to do single sided boards for less than $4 a
piece. You can shoot double sided with a little practice (I don't do this
yet). My method is great if your design crash and burns (you make a circuit
error). You can make a correction and reshoot in less than a day without
losing your shirt.
The quality of the etching and traces is every part as good as professional
boards. However, I have not tried making really fine traces. One thing I
strive for is to leave as much copper on the board as possible. This
creates large ground planes and requires less etching.

Hi Paul,
You keep mentioning about your article in quite a few conversation threads here in this forum. Is there a place to get it and read it online somehow ? Or can you send us a link to get to it ?
Looks like your article will help me a great deal with my miniature robot ?
thanks
nagi

I've seen a lot of folks reply this way, however, as a hobbyist (ie: one who
does not necessarily count the value of their time in the cost of a
product), who can build a quality single sided board for $4.00USD (that's
board, chemicals, etc), even $25 each is way more than I'm willing to spend.

it, He is making 4 boards I want 1, the cost of my one will be about
the same as his 4 if you are going to make multiple boards its best to
let some one else do it.

The article is set to be published in the December issue of Circuit Cellar
Inc. It should be available on the news stands next month. The magazine
has scanned the images and it looks like I have a contract in my email.
Apparently, its ready to go to the printer.

a leg to do this.

I have a plastic card a dermatologist gave me to test
for solar ultraviolet - it turns various shades and then
slowly resets - could this be useful for determining correct
PCB resist exposure? [noparse][[/noparse]presumably exposing it to the
UV source for x seconds where the circuit board will
be and reading the level from the card's color change...].
I have used sun lamps in the past [noparse][[/noparse]combination of mercury
arc capsule and tunsten] and exposure was always a bit hit or
miss. Perhaps the newer resist is more tolerant - haven't
used it - yet...
Thanks, premena

I picked up some UV beads at a science teachers conference last October that
do the same. It didn't occur to me to try them out on the UV table. I
guess the only problem is determing when the beads or card are at the right
level of color, or darkness. Does your card have a scale printed on it to
determine which level of darkness represents how much exposure?

I know the sun's level of intensity changes. That's why I prefer to use a
UV table with a constant light source.
