Hi Tom.



I'm very familiar with the 315. I would think that would be a great etcher
for home brewing pcb's.

Marty,

I built a small spray etcher many years ago using a "Little Giant"
pump and a quartz heater for use with ferric chloride. Now I use this
same unit to develop dry film photoresist. I used some HCL to clean
out the ferric chloride stains and it works great for dry film. This
etcher was modeled after the Kepro units but is just a bit larger so
it can handle a 18" x 24" panel. My main etcher now is an old Chemcut
315 which has oscillating spray bars and uses ferric chloride.

I use Micromat drilling machines, one for drilling and one dedicated
for routing. For prototypes I just use a scope drill. We soldermask
all of our boards mainly to keep the copper from tarnishing. I just
make boards for my own products and don't operate as a merchant shop
any longer.

I'm curious as to whether anyone has built their own home spray
etcher (a
small bench-top machine)? It would be fairly easy (albeit the time and
components required).



Cheers to you too! I'm guessing you're in the U.K. I'll be visiting
the
U.K. in about two months. Although I've made several business trips
over
there, this will be my first vacation (holiday). I'm looking forward
to it!
