Etch a single sided PCB

Etching is a printmaking process and where the excess copper is removed to leave the individual tracks on the circuit board. A muriatic or hydrochloric acid is important because it is used to remove the cooper layout on the circuit board.

The copper board can be cut into a necessary size needed and then clean it using a paper towel from any dust. Make sure our hands clean from any oil before touching the circuit board. Then place the pcb layout on a copper board and stick it using a masking tape.

Thus, get ready with a clothes iron and set the iron on the hottest setting to allow the iron get hot. Before start ironing the circuit board, use a thick clothes such as kain pelekat to sandwiching the copper board.

Firmly press the iron onto the back of the PCB layout for about 20 seconds and repeat the same method for more than 5 minutes. Without moving the iron, press board very hard for 1 minute to provide perfect heat to the circuit board. Then slowly move the iron around the copper board with a lot of pressure. After done with these methods, make sure the circuit board fully cool before removing the PCB layout from the copper board. 

Pour some hydrochloric acid on a plastic container and soak in the copper board into the acid. Wait for 4 minutes and shake the container slowly to remove the copper layout from the board.  The copper layout can be easily separate from the board by this method. Repeat the same method for 3 or 4 times to get a fully circuit board.

Separates the circuit board from the acid and leave it for 2 minutes. Wash the circuit board using clean water and brush the copper layout side using a sand paper. Repeat the same method until the copper layout completely removed.
