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. We believe this is an effective method for comparing the performance of multiple products by manufacturer, lot, etc. Additionally, we will support you from the design and fabrication of the test board.

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.

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 can measure the optical properties of LCD displays and OLEDs using a spectroradiometer. By conducting measurements before and after testing, we can quantitatively evaluate changes in optical properties. Spectral radiance is measured in four patterns: white, red, green, and blue. It is possible to measure various optical properties such as luminance, chromaticity, and dominant wavelength. *For more details about the products, 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)

We conducted hardness measurements on aluminum spot welds that were subjected to cross-sectional observation, and we would like to present an example of the trends observed in Vickers hardness, Young's modulus, and elasticity ratio. X-ray radiographic observation confirmed the presence of voids within the weld. Cross-sectional observation revealed that the central void was a blowhole. Furthermore, the results of the hardness measurements indicated that the area near the blowhole was hard but had low stiffness and was prone to deformation, while areas slightly away from the blowhole exhibited higher stiffness and were somewhat brittle. For more detailed information, please refer to the related products and catalogs.

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. For more details, please refer to the related products and catalog below.

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. For more details, please refer to the related products and catalog below.

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.

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
