➀ An innovative pilot line for vacuum coating and thermal post-treatment of flexible ultra-thin glass is established at Fraunhofer FEP. The process chain addresses issues from cleaning to in-line sputter coating and thermal post-treatment.➁ The technology aims to enhance the material properties of ultra-thin glass through flash lamp tempering and other methods.➂ Strength testing methods for ultra-thin glass are developed to optimize the material's performance.
