Total support service for cross-section grinding, processing, observation, and analysis.

At Aites Co., Ltd., we conduct "optical film analysis." Optical films used in smartphones and other devices have various functions depending on their structure and materials. We measured the light transmittance of privacy protection films at different angles and combined cross-sectional observation with Raman analysis to investigate the mechanism of function manifestation. By investigating the transmittance characteristics of privacy protection films using angle-variable spectrophotometry, we were able to analyze the mechanism of function manifestation through cross-sectional observation and Raman analysis. At Aites, we provide consistent evaluation and analysis from material properties to the mechanisms of function manifestation.

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 the NiP pad and Sn-Ag-Cu solder, compounds such as (Ni,Cu)3Sn4 and (Cu,Ni)6Sn5 grow, and surface analysis using EDX reveals 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, it may be feasible to analyze using the crystallographic data of Ni3Sn4 and Cu6Sn5 as substitutes.

We offer the "CP Processing Device Arblade5000_Wide Area Cross-Section Milling." The "Arblade5000" enables extensive processing by combining a high milling rate with wide area cross-section milling capabilities. With the wide area cross-section milling holder, the milling width can be expanded up to a maximum of 10mm, making it effective for electronic components that require wide area milling. 【Features】 ■ Approximately double the wide processing capability ■ Significantly expands the previously localized observation range ■ Equipped with a cooling temperature adjustment function to control temperature rise due to ion beam irradiation ■ The observable range is approximately 8mm

We will introduce the observation of metal structures through chemical treatment. By performing chemical treatment on metal samples, it is possible to clearly observe the metal structure. Observing the structure can reveal the condition of the sample and the history of applied heat and stress, providing clues about the quality of the product and any defects based on the structure's shape. In our catalog, you can find details on the observation of metal structures, such as the macrostructure of aluminum plates and the soldered parts of copper terminals. Additionally, we offer cross-sectional observation and various analysis services. Please feel free to contact us if you have any requests.
