Etching a pcb with bleach?? Answered


Yes i know there has been a question about this already... but im asking it again. Can you etch a pcb with bleach? I dont really want to go out and find ferric chloride or hydrochloric (muratic) acid :) I just wanted to know if this would work.  Also pros and cons would be good too, if not possible i can find a place with the right chemicals.. :)
Thanks!

You need the right counter-ions so that the copper dissolves rather then surface-corroding.
Bleach ain't best.

Get what works. Ammonia stinks and it's basic rather than acidic.

HCL you can get at a car battery place if you ask nicely, H2O2 you can get from a hair stylist's suppliers. Steve

HCL is pretty easy to get, even from a Janitorial suppliers, or as "brick cleaner" The Cupric chloride method is REALLY effective.
