The "tensile test" is a test that measures the load and displacement (elongation) when a material is pulled at a constant speed, in order to determine the physical and mechanical properties of the material. By pulling the test specimen in a temperature-controlled chamber, it is possible to determine and understand the temperature dependence of these properties. Our company is capable of conducting material property tests under temperature-controlled conditions. We can also propose conditions tailored to the materials and properties you wish to measure. Please feel free to consult with us.

"Dynamic SIMS" is a secondary ion mass spectrometry method that can detect trace amounts of all elements (from H to U) in samples with high sensitivity, ranging from ppm to ppb. It allows for qualitative analysis and depth profiling, and additionally enables high-precision quantitative analysis using standard samples (conducted at our partner company's facility). The minimum beam diameter is approximately 30 µm, and it can be further reduced depending on the material.

This is an example of evaluating the maximum pore diameter and pore size distribution of a non-woven fabric sheet using the bubble point method. The sample is immersed in a chemical solution, and air pressure is applied. The pressure is increased until it overcomes the surface tension of the chemical solution absorbed in the sheet, resulting in the appearance of bubbles; this pressure is referred to as the bubble point. The maximum pore diameter can be calculated based on the bubble point pressure and the surface tension of the chemical solution.

This article introduces a pretreatment method to enable the analysis of substances that are difficult to analyze using GC/MS. The pretreatment that converts difficult-to-analyze substances into analyzable forms is called "derivatization." Methods such as esterification, acylation, and silylation are used selectively according to the types and characteristics of the difficult-to-analyze substances. GC/MS measurements were conducted on citric acid solutions and citric acid solutions after esterification. It was found that citric acid, being a carboxylic acid, was not effectively detected without derivatization, but after esterification, trimethyl citrate was detected, confirming the presence of citric acid. By performing appropriate derivatization, more accurate analysis becomes possible.

We will introduce a case where a series of analyses from failure location identification to cross-sectional observation was conducted on oxide-based all-solid-state batteries that were destroyed by reliability testing. Thermal analysis revealed a tendency for strong heat generation on the side, and X-ray transmission observation showed a white linear contrast anomaly near the boundary where heat generation was observed in the X-ray transmission image. It is suspected that some abnormality is occurring in the white line area. When cross-sectional SEM observation was performed on the area where the anomaly was visible, layer delamination was observed. It is speculated that the positive (negative) electrode layers expanded and contracted repeatedly due to reliability testing, leading to delamination between the current collector and the electrolyte layer.

This is an introduction to the analysis of adhesive components in mica sheets using GC/MS. To investigate what components are contained in the mica sheets, spectroscopic measurements were conducted, suggesting that silicone-based adhesives are used. To determine the composition of the silicone-based adhesive, GC/MS measurements were performed. It was found that pentacyclooctasiloxane is used, and it was also discovered that dibutyl phthalate is added as a plasticizer and linear saturated hydrocarbons such as tridecane are added as lubricants.

This document introduces the characteristics of each spectroscopy method and the spectra obtained when comparing infrared spectroscopy and Raman spectroscopy. Both infrared spectroscopy and Raman spectroscopy are vibrational spectroscopies that investigate the vibrational energy of molecules, but the shapes of the spectra obtained from each method differ even when measuring the same substance. Infrared spectroscopy and Raman spectroscopy are complementary, and information that cannot be obtained from either analysis alone can be acquired more detailed and accurately by conducting both analyses. For more details, please refer to the published catalog.

This is an example of analyzing the purity of diphosphorus pentasulfide using ion chromatography for the composition analysis of raw materials for all-solid-state batteries. Diphosphorus pentasulfide is one of the raw materials used in the production of electrolytes for sulfide-based all-solid-state batteries. As a pretreatment for IC measurement, the powder of diphosphorus pentasulfide was dissolved in alkaline water and converted into phosphate and sulfide salts. Subsequently, the sulfide ions were oxidized to sulfate ions to prepare the IC measurement solution. For more details, please refer to the published catalog. We encourage you to take a look.

This article introduces a comparison between Raman spectroscopy analysis by AITES Inc. and FTIR. Spectroscopic analysis is suitable for component analysis of foreign substances and qualitative analysis. Both Raman and FT-IR can obtain spectra based on the structure of the analysis target. However, since each has its strengths and weaknesses, it is necessary to choose between the two depending on the analysis target.

We would like to introduce the dynamic viscoelasticity measurement of polyurethane rubber conducted by Aites Co., Ltd. DMA is an analysis that applies periodic oscillating loads to polymer materials and measures elasticity and viscosity as a function of temperature from the resulting stress and phase difference. In this instance, we conducted measurements using cylindrical rubber samples in compression mode. The measurement results indicated a glass transition temperature of -15.7°C from the temperature dispersion curve of Tan δ, and we created a master curve based on the time-temperature superposition principle. Please feel free to consult us when needed. 【Methods of Applying Load】 ■ Tension ■ Compression ■ Bending with both ends supported ■ Three-point bending with free support ■ Shear (sliding)

The "Pressure Repetition Test" involves supplying compressed air at a specified pressure to products that require airtightness, in order to check for any leaks. It is also possible to conduct a durability test that alternates between pressurized and released states, and this can be performed in a heated state in combination with an environmental testing chamber. Additionally, it is possible to confirm the timing of any leaks from the logged pressure data.

We would like to introduce our "Continuous Power Supply Test for Multilayer Ceramic Capacitors." Assuming the failure mode is a short circuit, we can conduct a continuous power supply test under high temperature and high humidity conditions while continuously measuring the changes in leakage current with direct current voltage.

When heat is applied to materials, various properties change. Thermal analysis is suitable for investigating such properties. Depending on the changes in the properties to be observed, different devices are used and combined as necessary. By understanding the various changes that occur when materials are subjected to heat, we can gain insights into how they will behave in practical applications. When combined with other chemical analyses, it is also possible to estimate relationships with molecular-level structures. For more details, please refer to the related materials. 【Analysis Equipment (Excerpt)】 <DSC (Differential Scanning Calorimeter)> ■ Changes observed: Heat flow (exothermic/endothermic) ■ Properties that can be determined: Melting point (freezing point), glass transition, crystallization, specific heat capacity ■ Applicable materials: Plastics, rubber, metals ■ Analysis examples: Measurement of the curing degree of thermosetting resins, measurement of the transformation temperature of shape memory alloys.

Our company conducts evaluations of brightness and color uniformity for emitting surfaces such as OLEDs, titled "Evaluation of Brightness and Color Uniformity in LCD Displays." In brightness measurement (using a two-dimensional luminance meter to measure the display surface), we compare the digital camera images of the LCD display surface with the results obtained from the luminance measurements conducted with the two-dimensional luminance meter. While the distribution of non-uniformity is difficult to discern in the digital camera images, the color scale display of the brightness distribution highlights areas with brightness non-uniformity, making it easier to understand.

The "Xenon Weather Meter" is an accelerated weathering test device that uses a xenon arc lamp as its light source. By combining exposure conditions such as irradiation, temperature and humidity, and rainfall, it artificially reproduces outdoor and indoor environments, allowing for the evaluation of weather resistance and light resistance of test specimens in a shorter time than natural exposure tests. The xenon lamp used as the light source has a spectral distribution that closely approximates the ultraviolet and visible parts of sunlight, with precise control over the use of appropriate filters and irradiance. This enables tests with good correlation and reproducibility to outdoor exposure. This testing is conducted as a service by our partner companies. For more detailed information, please refer to related products and catalogs.

The method of processing the observation samples may result in different information being obtained. You may have observed the solder joints in two dimensions from a cross-section, but have you ever wondered how the compounds are growing in three dimensions? In this document, we present examples of observations of the Cu pad and solder joint. We include both "cross-sectional observation" and "planar observation." For more details, please refer to the related products and catalogs below.

Due to the risk of depletion of natural ingredients, artificially synthesized alternative components may be used, and their identification is suitable through separation and analysis methods such as GCMS. This time, we focused on sandalwood (Byakudan), which is used as a raw material for incense. We tested whether the components of sandalwood could be detected in two types of incense (A and B) with sandalwood fragrance. In incense A, santanol was detected, whereas in incense B, santanol was not detected, and another fragrant component was found. Among these, bugdanol is a type of synthetic fragrance, and due to its structural characteristics, it is believed to have a sandalwood-like scent.

When a substance undergoes a phase transformation due to a change in temperature, a change in thermal energy occurs. Shape memory alloys are alloys that have the property of returning to their original shape when deformed and heated above a specific temperature. The manifestation of shape memory is due to a phase transformation (martensitic transformation). By capturing the thermal energy change during the transformation using DSC, we measured the transformation temperatures of three types of shape memory alloy products and investigated the relationship with their composition through elemental analysis. When a deformed wire is immersed in hot water, it instantly returns to its original shape.

Condensation caused by rapid changes in temperature and humidity can lead to corrosion of products and leaks or malfunctions due to ion migration. The "Condensation Cycle Test" involves temperature changes and humidification to forcibly and repeatedly generate condensation for evaluation against condensation. Additionally, we can observe the time-dependent changes before and after the condensation test, so please feel free to contact us if you need assistance. *For product details, please refer to the product page and catalog below.

Our company conducts solder heat resistance tests to evaluate the heat resistance of surface mount devices (SMD) during the solder mounting process. We replicate moisture absorption before mounting through humidification treatment and assess the presence of delamination or cracks through heating treatment that corresponds to the thermal stress during solder mounting. Additionally, as part of the post-test inspection, we perform inspections identical to the initial measurements and, if necessary, conduct analyses such as cross-sectional observations of defective parts. For more detailed information, please refer to the related products and catalogs.

Our company conducts "failure analysis of overseas displays." We can perform detailed analyses, from confirming the phenomenon to hypothesizing the failure mechanism and narrowing down the production processes that caused the issue. We carry out lighting observations, panel disassembly, and optical microscope observations tailored to the failure symptoms. If it is necessary to narrow down the defective areas and conduct a detailed analysis, we will propose appropriate methods.

We will introduce a case where ICP measurement was conducted using panels before and after reliability testing, along with quantification. The liquid crystal molecules in an LCD are oriented within the panel, and the display is controlled by changes in the orientation state of the liquid crystal due to voltage. When ionic substances, such as metal elements, are present inside the panel, the liquid crystal may not drive correctly, leading to display defects. It is known that ionic substances can increase due to contamination during manufacturing or long-term use, making it important to quantify and understand them as part of panel quality. Metal ions can be quantitatively analyzed using ICP analysis, and depending on the differences in pretreatment methods and detection sensitivity, ICP-AES and ICP-MS are used selectively. [Analysis Content] ■ Comparison of metal element content using ICP-AES analysis ■ Comparison of metal element content using ICP-MS analysis For more details, please refer to the related products and catalog below.

The blue light cut film has the effect of suppressing the transmission of visible light, particularly light with a wavelength of 500 nm or less, compared to regular PET film. Using a spectrophotometer, we verified how the light transmittance of the blue light cut film changes under UV irradiation. The transmittance of light in the wavelength range of 350 to 400 nm decreased further due to UV irradiation. Additionally, we conducted an analysis of the reactions occurring within the film using GC-MS. [Analysis Content] ■ Light transmittance characteristics of regular PET film and blue light cut film ■ UV irradiation of blue light cut film ■ GC-MS analysis of components within the film For more details, please refer to the related products and catalogs below.

At Aites Co., Ltd., high-temperature reverse bias testing (HTRB) for evaluating the oxide film and junction of power devices can be applied up to a maximum of 2000V. By monitoring the leakage current during the test, the degradation status of the device can be grasped in real-time. Since the power supply is independent, if one device fails during the test, it will not affect the other devices. Additionally, it is possible to set a failure criterion (current value) and to cut off the power supply to the device deemed faulty at the time of failure judgment. 【Specifications and Service Details】 ■ Test Voltage: Up to a maximum of DC 2000V ■ Applied Current: Up to a maximum of 14mA ■ Number of Test Devices: Up to a maximum of 8 (independent power supply) ■ Compatible Modules: TO-247, TO-220, etc. (other packages require consultation regarding connection methods) ■ Measurement Content: Monitoring of leakage current ■ Temperature Range: Up to a maximum of 200°C (85°C/85% in high temperature and high humidity conditions)
