I bought the items to try this quite some time ago and I needed a small relay board today and figure I would try it. Normally I use Ferric Chloride.
I was thinking I need to get rid of the acid since it had been sitting for some time in the garage.
It was a little bit faster (about 1/2 the time), I think less water would have worked much faster (did 1 acid x 1 h202 x 4 water; then added more acid and peroxide when I saw this was going too slow.) . So I estimate 1x1x1 in the end. Added the water, then H202 then HCL. Nothing blew up. Used rubber gloves as well not knowing what I might be getting into.
The price of the items were a lot less money though you delude and throw them out when done. Some of the acid dripped on the concrete floor and I received a good nose full and ran for the hose. The fan did not move it fast enough so I did get a good sniff. So it's the messy FC or breath something that burns if you make a mistake?
All in all, I will try it again and think I might like it better after I perfect the mix. It is great in a pinch anyway. The blue water was nice to look at.
The board looked pretty clean as well. Other than a trace I hit with a sharpie. Also, I would not leave it and forget it like FC, otherwise you might have no copper in the end.
