Etching Principle
Etching, also known as photochemical etching, means that through the plate exposure, after the development, the protective film of the area to be etched removed, the etching of the metal in contact with the chemical solution, the use of two positive graphics through the chemical flooding from both sides of the grinding to achieve the effect of dissolution corrosion, the formation of concave and convex or hollow molding effect. Chemical etching is very specific and refers exclusively to controlled corrosion, a controlled processing method of metal by chemical methods.
