Developing, Etching and Stripping

There are independent processes and in-line processes, such as DES (Developing, – Etching – Film Stripping) and SES (Film Stripping – Alkaline Etching – Tin Stripping).

Developing

Dry Film Development: it develops the film that is not exposed to the light, keeping the copper safe.

Solder Mask Development: it develops the mask of the zones that have not been exposed to the light, keeping the copper safe.

• Dosage controlled by several parameters. (PH, conductivity, etc.)
