We will introduce a case where precision planar grinding was applied to remove wiring and conductive particles from a glass substrate, allowing for the observation of IC chip circuits with minimal damage. Careful planar grinding was performed from the glass substrate side, removing material up to a few micrometers in front of the IC chip, enabling the observation of the circuit surface. The IC chip circuit surface was clearly visible, and detailed observation at high magnification became possible. There are many samples, like the one in this case, where detailed observation has been made possible through planar grinding, as well as samples that can undergo FIB processing or CP processing. If you have any samples that are causing you trouble, please consult with us. We accept requests for planar grinding only, as well as requests that include observation and analysis. For more details, please refer to the related products and catalogs below.

Here is an example of analyzing impurities confirmed from a solvent when high-purity products are stored in inappropriate environments. Ethanol stored in a light-protective reagent bottle in a cool, dark place was transferred to a used plastic wash bottle and left at room temperature for about a month. As a result, impurities such as triethyl borate and alkylbenzenes were detected. Additionally, acetone stored in a light-protective reagent bottle in a cool, dark place was transferred to a transparent glass bottle without light protection and left at room temperature for about a month, resulting in the detection of diacetone alcohol as an impurity.

Using fragrance as a keyword, we analyzed familiar incense and compared the characteristics of its molecular structure with other materials. The three representative fragrant woods obtained from trees are sandalwood, agarwood, and kyara, but this time we collected data on incense and sandalwood. Characterized by aldehyde groups and aliphatic cyclic structures, the woody scent is primarily believed to be caused by the aliphatic cyclic structure.

Are you having trouble evaluating whether the axes and the shaped holes are according to the design specifications? We attach samples to the KEYENCE "VR-6200" electric rotating unit and obtain 3D data by rotating it 360 degrees, measuring roundness from the profile. Additionally, we measure circularity using the image processing software "WinROOF2021." For more details, please refer to related products and catalogs. 【Features】 <Roundness Measurement Using VR-6200> ■ Attach the sample to the electric rotating unit and rotate it 360 degrees ■ Obtain 3D data and measure from the profile <Circularity Measurement Using Image Processing Software> ■ Using WinROOF2021, we measured the circularity of commercially available probe pins, and it was observed in the SEM image that they were not perfectly circular.

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 value, allowing for continuous profiling of hardness and indentation depth from the surface, as well as information on the effects on the material. By determining hardness values from the depth of penetration of the indenter into the material and the load/penetration depth curve after unloading, it is possible to analyze many physical properties beyond hardness, such as 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 related products and catalogs, or feel free to contact us.

Dynamic light scattering allows for the measurement of particle size and size distribution of nanoparticles dispersed in a liquid without separating the particles. Here, we present examples of particle size measurement for silica and alumina particles in an aqueous medium. Particles in a solution exhibit Brownian motion that depends on their size, and the fluctuations in the scattered light caused by illuminating the particles are also size-dependent. By observing and analyzing these fluctuations, we can determine the particle size and size distribution. [Alumina Measurement Results and Discussion] - As alumina approaches neutrality from a strongly alkaline condition, it nears its isoelectric point. - The surface charge of the particles decreases. - The repulsion between particles diminishes. - It can be inferred that particle aggregation is occurring. [Silica Measurement Results and Discussion] - It is believed that the isoelectric point is on the strongly acidic side. - In the pH range of 3 to 10, particle aggregation does not occur. - Particle size is maintained below 50 nm.

Liquid crystal displays use various organic materials, including liquid crystals, sealing materials, encapsulants, and polarizers. Considering the material properties and degradation mechanisms of each component from a chemical perspective is important for product evaluation and failure analysis. This document presents examples of chemical analyses for the components of liquid crystal displays. 【Examples of Chemical Analysis】 ■FT-IR: Principal component analysis ■EDX: Elemental analysis ■GCMS: Liquid crystal component analysis ■HS-GCMS: Outgassing analysis (degradation analysis) and others

Polyethylene (PE) has several types and different material properties depending on the length and number of its side chain branches. From the melting peak of crystalline polyethylene, we measured the melting point and crystallinity using DSC and compared them for each type of polyethylene. LDPE, which has many long side chains and is less dense, resulted in a low melting point and low crystallinity, while HDPE, which tends to be denser, showed high values for both melting point and crystallinity. Additionally, LLDPE, which has many relatively short side chains and is more likely to be dense than LDPE, exhibited intermediate values for both melting point and crystallinity between LDPE and HDPE. [Types of Polyethylene] ■ LDPE (Low-Density Polyethylene): Low rigidity and high flexibility ■ LLDPE (Linear Low-Density Polyethylene): Tougher than LDPE but has inferior processability ■ HDPE (High-Density Polyethylene): High rigidity and excellent tensile strength, impact strength, and hardness

"Laminating film" is used in various industries for the purpose of protecting the display surface while maintaining the visibility of printed materials by utilizing highly transparent materials. During processing, heat bonding is performed, so it is assumed that the molecular state changes compared to before processing. In this study, we attempted to clarify the residual stress remaining in the product by comparing conditions with and without heat applied to the laminating film, using birefringence. This document presents measurement results using a laminating film composed of polyethylene terephthalate (PET) and ethylene-vinyl acetate (EVA) as an example. [Contents] ■ Measurement of glass transition temperature by DSC ■ Measurement of birefringence by WPA ■ Effects of combining PET and EVA You can view related products and catalogs.

The introduction of the "FIB-SEM Helios 5 UC" is scheduled to start service in November. We will provide shorter delivery times and reliable feedback than before.
