Homebrew PCBs

yes, thanks, i read the page several times.

my problem isn't understanding the particular process, i have a severe lack of common chemistry 
knoweledge. i do understand the particular formulars but i don't know which factors have to apply to get 
such a reaction actually going on. (e.g. i dont understand what happens within my HCl H2O2 bath where 
initially there is zero CuCl2 but it too works immediately). I simply don't know why this happens....


sorry that i didn't figure that out more clearly..


regards

stefan
