3D construction by mechanical polishing

Introducing the advantages and disadvantages of 3D construction using X-ray CT and FIB slice cross-sections, as well as the 3D construction method using mechanical polishing!

We will introduce a case study of a 3D construction method using mechanical polishing. Ceramic capacitors have a structure where thin film electrodes are stacked internally, and X-ray CT cannot confirm the internal electrodes as they appear transparent. Additionally, 3D construction using FIB slice cross-sections is limited to localized confirmation due to the sample being only a few millimeters thick. The 3D construction method using mechanical polishing can complement the areas where X-ray CT and FIB slice cross-sections are not effective, allowing for 3D construction in some cases. [Case Study of 3D Construction of Ceramic Capacitors Using Mechanical Polishing] ■ X-ray CT image: Internal electrodes cannot be confirmed ■ 3D construction using FIB slice cross-sections: Limited to localized confirmation ■ 3D construction using mechanical polishing: Internal electrodes can be confirmed, allowing for extensive 3D observation *For more details, please refer to the PDF document or feel free to contact us.

basic information

**Advantages and Disadvantages of 3D Construction Using X-ray CT and FIB Slice Sections (Excerpt)** ■ X-ray CT - Method: The sample is rotated to obtain continuous 360-degree images, constructing a 3D image. - Advantages: Enables non-destructive 3D imaging. - Disadvantages: Not suitable for imaging heavy metals or thick samples as X-rays cannot penetrate them. ■ FIB Slice 3D - Method: Multiple cross-sections are created using FIB slicing, and images are obtained each time. - Advantages: Images can be magnified up to tens of thousands of times, allowing for sub-micron order 3D imaging. - Disadvantages: Not non-destructive due to the FIB processing. *For more details, please refer to the PDF document or feel free to contact us.*
