    Somewhat Complete PCB Fabrication

    To burn out copper fast, reliable and very inexpensive way, I am using a mixture of muriatic acid (20% HCl) and hydrogen peroxide 30% (can be obtained in drug stores), but the 18% that can be found in superstores works as well. I mix it 5:1, acid:hydrogen and heat it up during burning with ordinary bulb. It takes under 5 minutes to get the board done.
