Hello, am trying to make pcb at my home, but am not sure about the sequence of fabrication steps.
i put the board in UV light for several minutes, then i put it in a basic solution and finally in ana acidic one, but nothing happened to my board...
What are the names of bases and acids used for this purpose?
