New simple method for corrosion PCB

New simple method for corrosion PCB
By Ferric chloride hexahydrate can be very simple implementation of the diy pcb corrosion.

Features:
1. change all the shortcomings of ferric chloride, the corrosion rate is very fast.
2. It is blue and clear etching solution, no more dirty phenomenon.
3. etching process is clearly visible.
4. by 1:7 exchange water, can corrode 10 * 15cm single-sided PCB, about 10-15 pcs.

Found exactly this in a local electronics store here in Hong Kong.

It's ammonium persulphate, priced at HK$20 (about 3 usd) per pack.

Slower than ferric chloride, and have quite serious side-etching.
I think it is not so appropriate if you want to have SMD components on your board :)

Hi, I have one question, what is the diference betwen Ferric chloride Hexahydrate and the normal Ferric Chloride (FeCl3) because what I have is a dark brown, almost black liquid and hell it is slow!

can the hexahydrate version be made from this or what is it?

thanks,
emihackr97.

BTW 5 stars!

Give us in full chemical name would be much better to understand.
Also where can we get it, supplier name.

Quite sure this is in fact Ammonium Persulfate. This instructable contains very little information, perhaps a slideshow would be better.

I don't understand this - too little information. What is the blue stuff?

> It is Ferric chloride hexahydrate.
Can't be. No such thing in that color (nearly clear.) Probably sodium or ammonium persuphate.

Thanks, how does it change all the shortcomings of ferric chloride?
Ferrous would be blue, ferric is yellow/brown/orange - yes?
