Very fast etching 10 seconds!

2011-07-22 by leeleduc

I've been experimenting with etchants and have come up with a simple and fast one.

1 ounce Muriatic acid from the hardware store
1 ounce BAQUACIL Oxidizer from pool supply store (27% H2O2)

2 inch by 4 inch, 1 ounce solid copper. no traces. Etchant was at room temperature and I agitated the board with a foam paint brush.

Etch time 10 seconds!!!!!!!!!!!!!

give it a try.

BAQUACIL Oxidizer
A chlorine-free liquid oxidizer of 27% specially-stabilized hydrogen peroxide used to clarify pool water by oxidizing organic compounds (swimmer waste).

PS Do this outside wearing safety goggles! Lots of fumes.
