Introduction: 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.

Step 1:

by 1:7 'Blue etchant' into the water.

Step 2: Process of Corrosion Pcb Board

By the way, the etching agent is not blue: that colour comes from the Copper Sulphate that the reaction with copper produces.


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

L

It is Ferric chloride hexahydrate.


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

L

The chemical name is Sodium Metasilicate, Anhydrous

THIS IS CONFIRMED BY THE COMPANY (KINSTEN) http://kinsten.com.au/chem/

The company is from australia, and the product name is DP-50

And Kinsten have confirmed that this is blue?
There's no species in there that will produce a blue colour.

i´m going to ask them, i´ll reply when I got the answer

Hello,everyone. thanks for your interest.
The correct name is sodium Metasilicate or ammonium persulphate

Above address can confirm.

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

Sorry, I may not know the correct English name of the item.
But in the Chinese market, most technology students use it for class experiments.

I will verify that the correct name. And then released.
