System and method for controlling the application of acid etchers or cleaners by means of color-changing dye |
| abstract |
An acidic etcher solution for etching a substrate's surface. The acidic etcher solution includes an acid and a pH indicator, the pH indicator having at least one color transition at a pH below 7. The acidic etcher solution having an initial color at an initial pH when applied to the surface to allow determination of the evenness of the coating and the etcher having a second color at a second pH higher than the first pH wherein visual inspection allows for a determination that the etcher is substantially finished reacting. |
