Hi: Surfing the web I found your site. I also read the PCB Acid method. But I´m having several questions about the PCB connection. Must be the enameled wire soldered to it? I cannot figure out from pictures. Is there another way to fix the PCB (special non-corrode crocodile clips)? Thanks in advance Martin PD: I'm an electronics High School teacher so this method will help us (not using ferric chloride )

Hi Martin, I Found that Soldering an Enameled wire to it works best for me. The enamel coaing and the solder, both work fairly well in Avoiding being etched away. But you need to make sure tha no bare copper is left uncoated.
An Alligator or Crocodile Clip can be used but they will not last very long.
A High Quality Stainless Seel Clip would probably be good, If you could Find one? or Make One?
And you still need a "tiny bit" of Ferric Chloride to Finish off the Last little bit of Copper that the Electro-etch Process can't remove.
