'Anyone with a Home PCB Shop? [OT]'

Unusual one here;  I need some tiny PCB's, sizes like 10mm x 12mm or so,
for little adapters.  The first two aren't PIC-related, so I marked this
OT, the third one will be though, if I can get there from here.

I need about 1mm trace widths, double-sided boards, only 10 traces per
board or so, minimal VIAs & holes.  I could do it by hand, but would
rather NOT.  Really simple boards, just using PCB's for speed & accuracy
& to avoid having to crimp thousands of connector pins <G>  Don't need 4
mil traces on this one, & want it to be fairly cheap.

Is anyone on the list able to just plain make these for me, for a
reasonable number?  I need some soon, more later, and don't really want
to do all these via hand drawing, if I can avoid that;  I can do
drilling & cutting etc., if someone wants to take on this via a couple
sheets of those laser toner resist kits, and etch the board & tin it
(preferably.)  I figure one 6"x6" panel or so will last me for a while.

I have had to do this before and I think it cost around $50 at the time
to create a one off from a PCB manufacturer. (about 6 inch square which
gave me 36 small PCBs) Pick a small company and offer them cash in hand.
As a bonus they usually make more than one to be on the safe side and
you could end up with these for free.

You will be hard pressed to make PCB's with 1 mil traces in a home PCB shop.
Usually 8 mil is about all you can reliably do with a direct etch process in
a "home pcb shop"

True, but the original poster said 1mm, not 1mil. That's about 39mil. That
should be doable at home.

Have you tried expresspcb.com ?

They give you software, an upload process, and 2 or 3 day turnaround.

Great for small jobs, and when you get it right, you can get the gerber
files from expresspcb.

Also, if you are going to need a fairly large number of these boards, you
might consider purchasing the equipment necessary to make small quantities at
a time.  I have the Datak system which consists of the two sided copper clad
boards, photo resist board sensitizer, developing trays, transparent film for
my laser printer, 2 etching tanks which include heater and board holder with
air agitation, their Neg-fast film for making negatives from positives,
exposure frames (2  5"x6", 8"x10" are available) and instructions.  You can
also get software for your computer from Datak and it is very in-expensive or
you can download Eagle lite for free.  I use CircuitMaker/TraxMaker Pro suite
myself.

Everything for a large number of boards (less the software of course) is less
than $400.00 and the tanks can do boards up to 9"x9" two at a time.  If you
only purchase the number or items you need for one run the price would be
about half of what I just mentioned.  I purchased enough supplies for 50 or
so boards 3"x6" so for yours you would come out much cheaper.

All of the Datak line can be purchased from Jayco Electronics.  http://www.Jayco.com

I would offer to do these for you but alas I am covered up with my own
circuit board production.

Good Luck

Replying to several posts at once;

Jeff; I wrote "Don't need 4mil traces on this one" <G>  Professional PC
board shops, or home ones with **GOOD** gear and proper equipment, can
do 4mil or finer (Not direct toner transfer, I agree <G> but using film
you can get finer, with care);  For these projects, a trace width of
0.5millimeter or 1mm, which is 39 to 78 mils, is great - i.e., I could
draw these freehand, I just don't *want* to draw 100+ of these!

John; Money's tight (Taking on a bunch of big projects at once), I
e-mailed Tim and he's going to help, which should be great!

William; Thanks, he's already e-mailed me, this should be a good
workaround for this time!  He'll make me a panel, I'll be in good
shape.  I'll pass the favor on, of course <G>

Randy; I already have it all, except for the Direct Toner goodies, it's
all lost in the move (of course!), but at least the EMP-20, Picstart
Plus, Parallax programmer, EPRom erasers, gang EPRom programmer, and so
forth didn't disappear - THIS move.  I'll be getting a package of the
Direct Toner goodies, if Tim can take a week off my time needed here,
I'll have some money to work with sooner, which is good.  No bucks right
now for all of that;  My dad's off on vacation, so I can fix MY
problems, maybe I can find that box & have those nice Carbide drill bits
& so forth again.  Things are getting better now I'm single, so far,
mostly <G>

Been having a computer problem here, D: has been giving me "General
Failure writing to Drive D:", I finally figured THAT out today, bad
power cable pins, managed to fix them for now;  I need to replace them
later, but it can wait for now.  Added another drive to this machine,
and now IT's acting up, ARRGH, I'll figure it out.  May swap this 4Gb
drive out & put in a different drive, the machine's POST report says
it's a 107Mb drive, but FDisk, Format, PQMagicT, etc. do handle it
properly;  Except now I'm getting "General Failure writing to Drive E:",
the first partition on that drive.  I may have to replace this
motherboard, maybe that on-board HDC is sick?  Maybe it's just a loose
cable, I'm pretty disgusted with problems (& being out of HDD space)
here!  Mumble <G>

Related question for the group;  I will have the capability to plate
gold onto copper (or nickel or most anything else) pretty soon here;  Is
there an etchant that could be used, that would let me use gold as an
etch resist?  Ferric Chloride will (if hot at least) eat gold, IIRC,
just curious if this is possible;  it's definitely unusual, I know <G>

There was an ammonium persulfate (???) based etchant that was available in
the hobby market for a while.
Might try that.  Nitric and sulfuric acids might work too--bit of a
handling problem though.

I know a number of board houses that do work for HP use gold as a
resist--and Tin/lead is commonly used as a resist.
Would like to hear what you learn.

<G>  Nitric or sulphuric, a problem?  The mining folks I talk to always
have those on hand, and my dad's a research chemist, WHAT handling
problem?  (A fume hood can be a good idea...)  I could just hand the
boards off to him to etch at work <G>

HF, now, HCN, or SO2, THOSE can be dangerous...

I'll share info, no problem <G>  I've wondered about using EDM machining
for making PCB's, also, but I have more curiousity than time to do
research...  It's so slow, I've passed on it.
