Scratch testing of nanofilms for flexible electronics

Metallic nanofilms on polymer substrates are used for a variety of applications in flexible electronics. To ensure the reliability of such flexible electronic devices, the scratch adhesion property of the nanofilm is evaluated for the critical normal load as a part of R&D and QC activities. This application note explores the capabilities of Bruker’s scratch test system and includes an example of its evaluation of a metallic nanofilm on a polymer substrate.
