Example of analysis using the EBSD method
We will introduce an example of the analysis of EBSD patterns (Kikuchi patterns) at gold wire bond joints.
The EBSD (Electron Backscatter Diffraction) method obtains orientation information of individual crystals from the electron diffraction patterns generated by electron beam irradiation and maps this information. It is a technique used to investigate not only crystal orientation (texture) but also material microstructural states such as grain distribution and stress-strain as quantitative and statistical data. For example, when the sample is tilted significantly in a SEM and the electron beam is irradiated, if the sample is crystalline, electron diffraction occurs within the sample. By indexing the resulting pattern, it becomes possible to determine the crystal orientation at that point. By observing the differences in crystal orientation, it is possible to infer the residual stress within the crystal grains. 【Features】 ■ Obtains and maps orientation information of individual crystals ■ Investigates material microstructural states such as crystal orientation, grain distribution, and stress-strain ■ Allows inference of residual stress within crystal grains by observing differences in crystal orientation *For more details, please refer to the PDF document or feel free to contact us.
