I'm not happy with my etching. I'm using FR4, 1oz. copper boards. My copper cleaning is very thorough and my toner transfer is very dark and even. My etchant solution is two shot glasses of muratic acid and four shot glasses of hydrogen peroxide, ( I just use a shot glass glass to get even increments ). I put the board in the etchant and agitate for four to five minutes, or until all the copper is gone. It works pretty good but my copper is coming out dull an a little pitted, not nice and shiny and pretty like some of the the toner-transfer boards I've seen here. Not sure what I'm doing wrong. Should I use less hydrogen peroxide? I've etched a lot of boards and some of them turn out good but I think they can be better. Thanks.
