I just want to say no need for any dangerous chemicals if a simple
acrylic paint will do after soldering or a paint with colophony if you need
to protect
it before soldering.
If i can avoid a class 3 carcinogen i will do it, no matter how much
other dangerous substances there are commonly used.
And if one has to use it, because there is no substitute, i would
stress following the suggested safety precautions rather than saying
"other stuff nasty too".
I agree it is maybe the best electroless tinning, but still nothing
to handle without care.
no point in discussing this further (in my opinion).
st
and thanks to all for the many acid/water, water/acid descriptions.
i think i got the picture now ;-)
