보다 안전한 (?) 에칭용액

좀 약한 그래도 위험한 에칭용액

물 100 + 염산(10%) + 과산화수소 2%

You will make a 10% hydrochloric acid (HCl), 2% hydrogen peroxide (H2O2) solution. I used 40% HCL, and 30% H2O2 stock solutions, so I needed to dilute them more than most people would. I simply added enough water at the bottom of a plastic container to cover the circuit board. Next I added about 1/4 of the volume of HCl, and another 1/15th fo H2O2. Note that I didn't even measure. This is just a solution for eating the copper off the board, it doesn't need to be a detailed and precise solution. Wearing a lab-coat and rubber gloves (think dishwashing gloves) is probably a good idea.
