Trev,
The disposal of the chemistry for a setup the way I use it is much less
of a problem than it may seems. This is because
a) Most of the chemistry is the SAME I originally sat up 5 years ago.
It's still ok and as such there was nothing to dispose. I.e. the copper
bath for the electrolytics is one you probably can't kill ever :-)
b) Other baths just have to be replished with either distilated water or
some more chemistry.
The palladium bath is definately the most delicate one. I had to replace
it already about five times (if you want once every year). At the size
of my containers (2.2 liters for all baths except the copper one which
is 4.4liters) this does not really give a lot to dispose and the costs
for getting the expensive chemistry for this bath is also very
reasonable (~$20).
I just bring the used chemistry to the same place I also bring the used
etchant. Where I live, such small quantities can be given to any
drugstore. Here they are obliged to take such chemistry back and then
it's then collected at the drugstores once every month by a public
service and brought to a professional place that deals with it
acordingly. I'm aware that this is something which is probably different
in every country. The all important thing is that everywhere there is
chemistry which must be disposed propperly (i.e. painture etc. etc.) and
if you ask your local gouverment I'm sure you get the right guidance.
I for myself of course use my through plating and well, the complete PCB
manufacturing I do exclusively for prototypes. I never ever would want
to make a "series" production this way no matter how small it would be.
In other words, I use a professional PCB service for everything that
goes into production. I consider boards I make for personal use of
course to be prototypes.
As for the web page, I know I'm "behind". I will set up such a page. I
alredy registered a domain for it and belive it or not, I'm truly
working on it right now :-). That of course should not hinder you to set
up whatever page/information you like. I just want to state that I will
put up the pages as promissed. Workload job wise just slowed things
down, and since I have quite something in mind about it it will also
take some more time until it's ready.
