Re: Circuit board construction for the ATMer...?

Congratulations on learning how to do multilayer boards!
Next you will be expanding out to do boards for others and that's when
you're going to be getting into real trouble.
I've been working in the engineering area of electonics on the bleeding edge
of technology at times and the production of PCBs is always a big problem
for small companies.  I started out when the boards were laid out by hand on
clear acetate and now have several board layout programs for doing that job.
The messing around with the chemicals and boards themselves is something
that I have always left to the board houses (in my area, they are all over -
practically in every shopping center) to do.  I've gotten 2 day turnaround
at the best but for a real price increase.  Doing the manufacture of the
boards inhouse is something that any decent sized company seems to always
end up doing and it seems that your company has decided to go that way.
What you need to do now is to put together a website of your experiences in
making the shop and let everybody else find out how it's done.
I, at the present, consider that a 4 layer board to be the minimum number of
layers on a board in order to control the power source resistance and
inductance.  Then again, I rarely deal with stuff that is less than 1MHz in
speed and/or low level analog signals.
