Cross-sectional observation of substrate-mounted components (1) to (6)
Introducing the "Observation Mode" of a chip capacitor (MLCC) under a microscope!
We would like to introduce an example of cross-sectional observation of mounted components conducted by our company. Using commercially available computer circuit boards, we observed the solder joints of mounted components and the internal structures of the components with a metallurgical microscope. The observation modes of the metallurgical microscope include bright field observation, dark field observation, and polarized light observation, among others. Additionally, there are observations using transmitted light, and the observation mode is selected according to the sample. By conducting cross-sectional observations before and after reliability testing, we can evaluate the reliability of the product. When observing, it is important to select an appropriate "observation mode" to clearly capture the condition of the solder joint interface and defects such as cracks.
