| | a) | b) | c) | | | a) We use ferric chloride as our etchant\\ based on the [[ https://www.polymetaal.nl/beguin/mape/edinburgh_etch.htm|Edinburgh Etch for Copper mix]]\\ 1 liter saturated ferric chloride solution(40%)\\ 200ml tap water, 66.6g citric acid\\ working temperature 50C.\\ work with disposable gloves on etching part! | b) Etching time takes around 7 - 20 min.\\ depends on clad size and copper surface to etch. | c) Once Circuit is fully etched\\ rinse it gently with water.\\ Place Etched Circuit on a kitchen towel\\ and let it dry.| |

| | a) | b) | c) | | | a) Place etched circuit in a plastic container.\\ pour acetone on the circuit and wait few seconds\\ till the photosensitive dry film dissolves. | b) Wipe gently the dissolved photosensitive dry\\ film. use a cotton ball. | c) Once all the photosensitive dry film is removed\\ from copper traces. rinse the circuit with water.\\ Place Etched Circuit on a kitchen towel\\ and let it dry. Done! | |
