We will introduce the observation of the shape of conductive particles in COG implementation. ICs and liquid crystal panels are implemented using the COG method with ACF (anisotropic conductive film). A resin ball is used as the core, and a metal layer (such as nickel or gold) is deposited on its surface for conductivity.

To confirm the degree of particle deformation and the connection state, cross-sectional observations were conducted, revealing that the amount of particle deformation was "medium," indicating an appropriate level of deformation. By examining the deformation of conductive particles from both the planar and cross-sectional perspectives, we can explore the correlation with display defects.

We present a case study of a series of analyses conducted to identify failure points and perform cross-sectional observations on an oxide-based all-solid-state battery that was destroyed during reliability testing. Thermal analysis revealed a tendency for strong heat generation on the side, and X-ray transmission observations showed white linear contrast anomalies near the boundary where heat generation was observed in the X-ray transmission image.

From X-ray radiographic observations, voids were confirmed within the weld area. Cross-sectional observations revealed that the void in the center was a blowhole. Additionally, the hardness measurement results indicated that the area near the blowhole was hard but had low stiffness, making it prone to deformation, while areas slightly away from the blowhole exhibited higher stiffness and were somewhat brittle. [Summary] ■ Observation case of aluminum spot welds: optical microscope images, X-ray images - Voids confirmed within the weld area from X-ray radiographic observations ■ Hardness measurement of cross-section of aluminum spot welds - Measurements conducted focusing on the blowhole - Investigation of trends based on Vickers hardness, Young's modulus, and elasticity ratio *For more details, please refer to the PDF document or feel free to contact us.

Are you having trouble evaluating whether the axes and shaped holes are according to the design specifications? At our company, we attach samples to the KEYENCE "VR-6200" electric rotary unit, rotate them 360 degrees to obtain 3D data, and measure roundness from the profile. Additionally, we measure circularity using the image processing software "WinROOF2021." Please feel free to contact us when you need our services. 【Features】 <Roundness Measurement Using VR-6200> ■ Attach samples to the electric rotary unit and rotate them 360 degrees ■ Obtain 3D data and measure from the profile <Circularity Measurement Using Image Processing Software> ■ When measuring the circularity of commercially available probe pins using WinROOF2021, it was observed in the SEM image that they are not perfectly circular. *For more details, please refer to the PDF document or feel free to contact us.

Our company can perform ultra-microhardness measurements on various materials such as metals, polymers, plastics, and ceramics. Additionally, since hardness can be quantified, the characteristics of the materials become clearer. The ultra-microhardness tester "Fischer scope H100" measures by gradually increasing the load up to the set load, allowing for the continuous profiling of hardness, indentation depth, and information on the effects on the material from the surface layer. By determining the hardness value from the penetration depth of the indenter into the material and the load/penetration depth curve after unloading, it is possible to analyze many physical properties beyond hardness, including Young's modulus, plastic hardness, plastic deformation amount, elastic ratio, and creep. Please feel free to contact us if you are considering evaluating the characteristics of materials. *For more details, please refer to the PDF document or feel free to contact us.
