Hi!
I've started to learn home pcb manufacturing methods. And I need an opinion about the etching powder. There are two options available for me:
1. sodium persulfate
2. ferrichloride
(sorry, if names are bad, just trying to translate it from finnish to english. Please correct me if translation is wrong. Would be good to know right names.)
So, I would like to know, which one is better (if any difference), which one is less dangerous for human beings, etc ...
PS!
I'm speaking about famous "toner transfer" method, if that makes any difference.
