Anyone here have experience etching PC boards with ammonium persulfate? I
received some from a friend but have not tried it out. According to the old
ARRL handbooks one needs an activator (mercuric chloride) but I noticed in
the local electronics store that it is sold without activator.

What's up?

Brad;
Ammonium persulfate is a potential explosive as I recall.
Mercuric chloride is a poison and carcinogen.
Take care and employ all precautions.
