Assalamualaikum..
We already in week 6 and its good for us that everything
smoothly on the right track. In this week we continue our project progress with
etching process. Etching is a process where the copper is removed from the
board by using an acid. The board is immersed on the acidic solution and let
the solution to run through. The acidic solution is formed by mixing some
needed amount of acid powder and water. The amount of powder used is determined
by the size of board to be etched.
Here, I have provided
some picture regarding the etching process.
