Fellow TechNetters:

   Is there any possible way to make the above stated etchant STRONGER/AGGRESSIVE:   Here are the chemicals:   Perhaps by varying the volume of one of the three constituents.

1   -      Ammonium Hydroxide, 28.0 - 30.0%
1   -      Hydrogen Peroxide, 3%
1  -       Deionized water

Victor,
