Hello everyone! We made a video how to make a printed circuit boards using diode laser installed on a 3D printer (or you can put on any CNC mill). The idea is that you cover copper board with a vinyl film and then remove it with a diode laser. The simply put into Ferrum chloride. If anyone has an idea how to make edges more accurate, please let us know. Skype:george.fomitchev E-mail:[email protected]
