DIN EN 62047-18:2014-04

The main structural materials for MEMS, micromachines, etcetera, have special features, such as a few micron meter size, material fabrication by deposition, photolithography, and/or nonmechanical machining test piece. Thin films are used as main structural materials for MEMS and micromachines. This document specifies the bend testing and test piece shape for micro-sized smooth cantilever type test pieces, which enables a guarantee of accuracy corresponding to the special features. The test method is applicable for bend testing of thin film materials with a length and width under 1 mm and a thickness in the range between 0,1 µm and 10 µm. In addition to provisions for the production of micro test pieces and test performance, the document provides informative notes to the contact surface between the micro sample and substrate, and the relationship between force and displacement.
