It is also possible to display various maps of each phase! Analysis is based on the information of the crystal structure possessed by the sample.

We will introduce an example of the analysis of compounds formed at the interface between Sn-Ag-Cu solder and NiP pads. At the interface between NiP pads and Sn-Ag-Cu solder, compounds such as (Ni,Cu)3Sn4 and (Cu,Ni)6Sn5 grow, and surface analysis using EDX shows the distribution of Ni, Cu, and Sn within these compounds. The EBSD method is an analytical technique based on the crystallographic information of the sample. By combining it with elemental analysis using EDX, it is possible to estimate the composition, and in some cases, analysis can be performed using the crystallographic data of Ni3Sn4 and Cu6Sn5 as substitutes. 【Overview】 <Elemental Analysis by EDX> ■ Surface analysis shows the distribution of Ni, Cu, and Sn within the compounds. <Crystallographic Orientation Analysis by EBSD> ■ By combining it with elemental analysis using EDX, it is possible to estimate the composition. ■ In some cases, analysis can be performed using the crystallographic data of Ni3Sn4 and Cu6Sn5 as substitutes. *For more details, please download the PDF or feel free to contact us.

Changes in crystal orientation and crystal grain size can be analyzed! We introduce the EBSD (Electron Backscatter Diffraction) method.

The EBSD method is a technique for analyzing the distribution of crystal grains, microstructure, and crystal phase distribution by calculating the crystal orientation of patterns continuously captured based on the information of the crystal structure of the sample. Materials such as metals and ceramics, which are crystalline, are thought to be composed of numerous crystal lattices like cubes, and this analysis method examines the orientation of these lattices (crystal orientation). Various maps are used, including the IQ map (Image Quality Map), IPF map, GROD map, and pole figures. 【Features】 ■ The EBSD method is a technique for analyzing the distribution of crystal grains, microstructure, and crystal phase distribution. ■ Uses the TSL Solutions OIM7.0 crystal orientation analysis device. ■ Analyzes the orientation of the crystal lattice (crystal orientation). ■ Changes in crystal orientation and grain size due to different processing conditions (such as rolling and extrusion) can be analyzed. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce an example of analyzing EBSD patterns (Kikuchi patterns) at gold wire bond joints.

The EBSD (Electron Backscatter Diffraction) method obtains orientation information of individual crystals from the backscattered electron diffraction patterns generated by electron beam irradiation and maps it. Furthermore, it is a technique for investigating 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 an SEM and the electron beam is irradiated, if the sample is crystalline, electron beam diffraction occurs within the sample. By indexing that 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.*
