The main advantages of flexible electronics in comparison to conventional rigid technologies are light-weight design, mechanical and topological flexibility as well as large area and cost-effective production. For realization of these advantages in a device not only development of novel appropriate materials and fabrication methods but also understanding of reliability issues and failure mechanisms are required. In this contribution the basic failure mechanisms observed in silver metallizations on flexible substrates are overviewed for monotonic tensile, cyclic tensile, and bending tensile and compressive loading conditions. A clear size effect in the fracture of thin films is demonstrated by comparing mechanical reliability of evaporated lines of different thicknesses and grain sizes with printed nanocrystalline silver. It is also shown that the correlation between electrical degradation and mechanical damage induced by cyclic mechanical loading is non-trivial and requires detailed information about the cracking morphology.
