Electro-optical conductor plate manufacturing method for e.g. mirror module, involves applying and structuring mantle layer such that mantle layer does not cover non-transparent surface, and removing material from surface to form mark

摘要

The method involves forming a non-transparent surface on a substrate (1) e.g. polyimide. An underlayer (2) is applied on the substrate, and the underlayer is structured such that the underlayer does not cover the non-transparent surface. A core layer (4) is applied, where the core layer and the underlayer cover the non-transparent surface. A mantle layer (5) is applied and structured such that the mantle layer does not cover the non-transparent surface. Material is removed from the non-transparent surface within a structured area to form a reference mark (30).
