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).

Acid Etching

It is a process used for inner layers, where the film’s unprotected copper is stripped.

  • High quality etching using the Lumiplas system.
  • Uniform etching.
  • Dosage controlled by several parameters. (Redox, Conductivity, density, etc.).
