This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2018-12-14 to 2019-01-25. By purchasing this FDIS now, you will automatically receive, in addition, the final publication.

IEC 62951-4:2019 specifies an evaluation method of fatigue properties of flexible films and flexible substrates for flexible semiconductor devices. The object of this document is to establish the preferred test methods for evaluation of the bending fatigue properties of conductive thin film on substrate for the application at flexible semiconductor devices. The films include any films deposited or bonded onto a non-conductive flexible substrate such as thin metal film, transparent conducting electrode, and thin silicon film used for flexible semiconductor devices. The electrical and mechanical behaviours of films on the substrate are evaluated. The fatigue test methods include dynamic bending fatigue test and static bending fatigue test.
