Here is an example of failure analysis of chip resistors where abnormalities were observed. Upon investigating the cause of malfunction in the polishing table, abnormalities were confirmed in the chip resistors on the relevant board. Surface observation revealed abnormalities in the chip resistors, and it appeared that the protective film was melted. Elemental analysis using EDX detected elements such as Al and Pb from the abnormal area, raising suspicions that the undercoat layer may be exposed. Next, cross-sectional samples were prepared through mechanical polishing, and analysis was conducted using SEM/EDX, which showed that the protective film and resistive material appeared to be melted. At Aites, we consider and propose processing, pretreatment, observation methods, and combinations tailored to the observation objectives and the composition and structure of the samples based on our accumulated know-how.

We will introduce a case where the rebound and vibration absorption properties of rubber materials were evaluated using dynamic mechanical analysis (DMA). In the "Comparison of Vibration Absorption of Rubber (Temperature Dispersion Measurement)," dynamic mechanical analysis was conducted using two types of rubber materials. Rubber A is considered to have superior vibration absorption properties (lower rebound) than Rubber B, with larger E" and tanδ in temperature ranges above -10°C. In the "Comparison of Vibration Absorption of Rubber (Frequency Dispersion Measurement - Master Curve)," the dynamic mechanical properties of Rubber A and B were compared across frequencies. By creating a master curve, it is also possible to predict viscoelastic behavior in frequency ranges that cannot be measured directly. 【Measurement Details】 ■ Comparison of Vibration Absorption of Rubber (Temperature Dispersion Measurement) - Rubber A is considered to have superior vibration absorption properties (lower rebound) than Rubber B, with larger E" and tanδ in temperature ranges above -10°C. ■ Comparison of Vibration Absorption of Rubber (Frequency Dispersion Measurement - Master Curve) - Rubber A is considered to have superior vibration absorption properties than Rubber B, with larger tanδ over a wider frequency range. *For more details, please download the PDF or feel free to contact us.
