Homebrew PCBs

That site put me on the trail of sodium perborate. It is unclear how he is using it. If you want hydrogen peroxide then you need to dissolve it in water. The crystals are a source of active oxygen so maybe this is all you need with the acid. I never really followed up on this. I am using the Edinburgh etch version of ferric chloride for my boards.
