The first part is a UV light, which is used to develop a photo-sensitive PCB. Once this has been done. The PCB has to be treated with sodium hydroxide (NaOH) dissolved in water. This removes the UV-sensitive plastic, where it has been tackeled by the light. +The etching machine consists basically out of two parts.
