For The Etching Method :-

1. Boil Approx. 500 ml Of Water In A Utensil For 15-20 Minutes. The Hotter The Water is, The Less Time The Etching Method Will Take.

2. Pour Ferric Chloride In The Small Container.

3. Now, Pour The Boiling Water In Ferric Chloride. (The Hotter The Water is, The Less Time The Etching Method Will Take) (Do Not Completely Fill the Container)

4. Also Pour the Boiling Water In The Big Container (Again, Do Not Completely Fill It)

5. Now Put The Small Container In The Big Container, After Doing That Put The Board In The Small Container

6. Keep Checking That The Copper Is Removed Or Not.
Hold The Board With Tweezers(Not With Hands Like I Am Doing, As It Is A Chemical).

7. If The Copper Is Completely Removed(Like This) Then, The Etching Is Done.
