"Energy Dispersive X-ray Spectroscopy (EDS or EDX)" is a method that detects characteristic X-rays generated by electron beam irradiation using a detector attached to an electron microscope (SEM or TEM), allowing for the acquisition of elemental information about samples or foreign substances. When characteristic X-rays generated by irradiating a material with an electron beam enter the detector, a number of electron-hole pairs equivalent to the energy of the characteristic X-rays are produced. By measuring this number (current), it is possible to determine the energy of the characteristic X-rays, and since the energy varies by element, it is possible to investigate the elemental information of the material. [Analysis by EDS (partial)] ■ Qualitative analysis of intermetallic compounds (point analysis) - By examining which elemental characteristic X-ray energy corresponds to the characteristic X-rays in the measured spectrum, the types of elements can be investigated. ■ Semi-quantitative analysis of intermetallic compounds - By examining the intensity (count number) of each characteristic X-ray, the concentration of the contained elements can be calculated. *For more details, please refer to the PDF document or feel free to contact us.

Carbon materials include various types such as graphite, activated carbon, and carbon fibers, and are widely used in applications such as the active material for the negative electrode of lithium-ion batteries, additives for conductive plastics, inks, and CFRP. Our company evaluates the structural differences of carbon materials through Raman analysis. In the case of carbon black (CB) and activated carbon, the G-band peak becomes broader compared to graphite, and the full width at half maximum increases. This indicates that the crystallite size differs, with graphite having a larger crystallite size than CB and activated carbon. **Differences in Raman spectra due to carbon materials:** - Graphite shows a strong and sharp G-band around 1580 cm-1. - It indicates the disorder in the hexagonal structure, which is the unit cell of graphite, and the stacking of layers is more disordered. - In CB and activated carbon, the G-band peak is broader compared to graphite, and the full width at half maximum is larger. - Graphite has a larger crystallite size than CB and activated carbon. *For more details, please refer to the PDF document or feel free to contact us.*

Additionally, average data can be obtained for sample surfaces larger than a few centimeters, making it suitable for relative comparisons of flat samples such as printed circuit boards. You can view the analysis flow for liquid samples and solid surfaces by downloading the PDF below. 【Overview of Liquid Sample Analysis】 ■ Liquid samples are introduced into the device for measurement after solution preparation such as dilution and filtration. ■ Measurement results are reported in solution concentration [mg/L]. *For more details, please refer to the PDF document or feel free to contact us.

In our evaluation of the properties of various materials, it can be said that glass plates with less indentation are harder, while plastic cases with more indentation are softer. Additionally, glass plates and plastic cases with a high recovery amount have a higher proportion of elasticity, whereas metals with a low recovery amount have a higher proportion of plasticity. Furthermore, we also evaluate material properties that can be understood from the diagrams. Please feel free to contact us if you have any inquiries. 【Overview】 ■ Evaluation of the properties of various materials ■ Material properties that can be understood from diagrams *For more details, please refer to the PDF document or feel free to contact us.

After the solder durability test on the circuit board, if cracks occur in the solder joints, the crack rate will be calculated to confirm whether the cracks are within the allowable standards. The evaluation standards after the solder durability test can be individually defined based on the product environmental specifications, so most customers have their own standards. The measurement methods vary according to the shape of the components, but when you make a request, we will carry out the tests according to your specifications. 【Service Contents】 ■ Solder joints of BGA - Calculation of crack rate for ball joints ■ Solder joints of chip resistors - Calculation of crack rate for both ends of square and rectangular terminals ■ Solder joints of coil components - Calculation of crack rate for ribbon leads and QFP leads *For more details, please refer to the PDF document or feel free to contact us.
