I dont think anybody here recently said you need to add copper sulfate, as
we all now know, as soon as you put the first board in, you have some.
Unless the board was micro sized, I personally cannot believe you had a 1
min etch with no gassing, but that's just from my experience. I'm thinking
your h202 was a bit stronger than maybe you anticipated.
Anyway very glad it's working for you. ~But I think it better to donate the
FeCl to your local haz mat disposer than to pass the curse on. : )
