You need to use sodium hydroxide (7 g/L) which is a base to dissolve the UV resist. Muriatic acid is, well, an acid, and won't do anything... Check my how-to! Though I need to correct some of the equations for the etching part (back then I missed one reactant, but I need some extra cinetics data)...culturejam wrote:The problem is that muriatic slowly dissolves the UV resist, so it doesn't work out at all.

I did it in my kitchen this winter (reactions are temperature dependant). No problem , no bad smell, no nothing).Chugs wrote:Sounds like something my girlfriend might let me do in the house. She is adverse to the idea of me etching boards with "vats of chemicals", as she so eloquently puts it.
