what is photo etching?
"Chemical etching (photo etching) is a photo-lithographic process whereby a phototool is used to block UV light from exposing the area of a sheet of metal which has first been cleaned and laminated with photoresist. The sheet is developed which washes away the unexposed photoresist leaving a very precise mask of hardened photoresist behind. This patterned sheet is then exposed to concentrated etchants which very precisely dissolve any exposed material."
