Recently I found in the Internet at a very cheap solution for etching PCB. To make it you need components which total cost not more than $0.5.
Previously, I etched with ferric chloride, and then used sodium persulfate, which does not stain. However, the solution I found is better and faster that both of them!


    For 40 ml PCB etching fluid
  • Hydrogen peroxide
  • Lemon acid
  • Salt

  • Pickling tank
