That board will take less than 2 minutes in 40% to 50% Nitric acid solution with ordinary tap water. You will need only half a cup of solution! No aeration or agitation needed, just keep your eye on it and work in a well ventilated area. When done dilute the solution well and discard. I have done it 1000's of times. Ferric Chloride be dammed!!!!!
When done dilute the solution well and discard. exactly why would you dilute a toxic substance that contains copper which is harmful to the environment, animals and people, you just end up with more volume of toxin. Exactly where are you discarding this toxin? I bet the New Zealand EPA would like to hear about it! A regenerative Solution like Acid Copper II is not about instant Self Gratification. Is about using a etching solution the is environmentally responsible!
Copper(II) aka (Cu2) is a oxide and is not a acid. Copper(II) Chloride / Cupric Chloride(CuCl2) however is. Stuff is easily made with a solution HCI(hydrochloric acid) and H202(hydrogen peroxide). The H202 will oxidize Cu to Cu2 and will desolve into the HCI to form CuCI2. And its no diffrent then FeCl3 in "regeneration", as there is only so meny Chloride ions to go around in the solution excess will just revert to Cu1 and 2
Peroxy-sulfuric Sound like a mix of Hydrogen Peroxide and Sulfuric Acid? What are the byproducts are any of them extremely dangerous and is it self sustaining after you mix the solution or do you discard the mix and start with a new batch of Peroxy-sulfuric each time?
I have used ferric chloride to produce many, many boards for hobby purposes back in the old ham radio days, but have not made boards lately.
Now that I am breadboarding some circuits for solar heating control and picaxe controlled devices, I had made a note to pick up some ferric chloride from Radio Shack.
After reading the above post, I guess RS doesn't carry it anymore?
I was not aware of an alternative etching solution until now. Thanks very much!
You are so right, it is 8 to 10 times faster, But look at it this way, Whats a quart of Ferric Chloride cost, Oh Mouser has it for 11$ 33oz bottle. Plus shipping. And a minimum of 6 bottles, thats 66$ order and shipping on top and ferric chloride cant be lite. I cant get it localy it has been banned from my local stores here in the USA.
How many square inches can you etch with a cup full of ferric chloride? I have used 1 cups of Muriatic Acid(Hydrochloric Acid)when I filmed this video and added 1 more to increase the volume. Total cost 5$ for a Quart, I am still using the same solution; I dont have any waist to dispose of. It a crime to knowingly pour hazardous waist down the drain. Big fines! My total surface area is around 92 Square inches. A win win solution. I watch TV while it etches.
You know if you used hydroflouric acid you'd clear that board and your cold in no time!

You must be doing something wrong. I etched a board 160x200mm (remove all copper - double sided) in less than 5 minutes with peroxy-sulfuric.

I believe hes refuring to Peroxymonosulfuric acid (H2SO5) aka peroxysulfuric acid.

Okay, now I've etched a board with it and it worked very well!
Thanks again!

well it's better to use ferric chloride. It took about 5 mins. to etch my printed circuit board and its done.

oh ok. well I don't know that it was banned there. anyway since ferric chloride was really bad. I may try your solution.
I just bought my ferric chloride for about 12$ but about 1L more.

Nice job ,hope that's a cold and not the acid...

This is a fascinating series. I had no idea that you could do this kind of work in a home shop.
