Hey everyone, I am completely new to electronics and I am trying to make a circuit board.
1st. I transferred the printed circuit onto photo paper with an iron.
2nd. I immersed the pcb in the ferric chloride that I prepared, I think with a higher concentration than recommended. I left it on for 15 minutes and since I didn't see much happening, I took it out and removed the toner with acetone.
As I saw that it wouldn't come out, I passed it a fine sandpaper, and that's when I realized that the ferrous chloride hadn't had an effect.
Does anyone have any advice or have an idea of what might have happened?
