Anotace

IEC 62047-52:2026 specifies a testing method for measuring device performance and failure strain under biaxial tensile deformation in stretchable MEMS materials. The typical examples of the stretchable MEMS materials are flexible single crystalline silicon structures, MEMS circuit boards, interconnected MEMS on a stretchable substrate. The test piece has a cruciform geometry and the test piece thickness ranges from 1 µm to 100 µm with the same thickness as the actual devices. Since the failure strain can vary depending on loading conditions like uniaxial tension and equi-biaxial tension, a biaxial load is applied to a cruciform test piece with varying strain ratio between two perpendicular loading directions.
