Cryogenic ion milling cross-section processing example (rubber products)

We will introduce a case study on the method of processing cross-sections using toy car tires!

We would like to introduce a case where cross-sections were created and observed for the adhesive parts of pull-back car tires using different methods. Upon conducting SEM observations of the created cross-sections, fillers present within the rubber were confirmed. It was found that the dispersion state of the fillers and the appearance of the adhesive interface were not clear with liquid nitrogen fracturing or mechanical polishing. In contrast, the cross-sections created by cryo ion milling allowed for a clear observation of the dispersion state of the fillers contained in the rubber and the appearance of the adhesive interface with the plastic substrate. 【Cross-section Preparation Methods】 ■ Liquid Nitrogen Fracturing (-196℃) ■ Mechanical Polishing ■ Cryo CP (-150℃) *For more details, please download the PDF or feel free to contact us.

By applying chemical etching, ion milling, and FIB processing to mechanical polishing, we will analyze various metal joints, starting with lead-free solder.

The joints of electronic components have a significant impact on the overall reliability of the circuit board. Particularly at solder joints, it is important to observe not only the shape but also the metal structure.

Depth-direction measurements using Raman spectroscopy! Material analysis of each layer is possible from the surface of multilayer films.

Our "Micro Raman Spectrophotometer" employs a confocal optical system, allowing for the adjustment of the focal position in the depth direction, similar to a microscope, enabling material analysis of each layer from the surface of multilayer films. Using the confocal function of the micro Raman spectrophotometer, the focus of the Raman laser light can be varied in the depth direction. Additionally, by continuously changing the focal position, it is possible to obtain spectra continuously in the depth direction. 【Features】 ■ Adoption of a confocal optical system ■ Enables material analysis of each layer from the surface of multilayer films ■ Capable of varying the focus of the Raman laser light in the depth direction ■ Allows for continuous spectral acquisition in the depth direction *For more details, please refer to the PDF document or feel free to contact us.

We are publishing the main cross-section manufacturing methods, processing conditions, advantages & disadvantages, etc.!

This document introduces methods for preparing cross-sections. When conducting observations, analyses, or evaluations, there may be a need to prepare cross-sections. By selecting or combining methods that are appropriate for the purpose, material, and structure, it is possible to obtain highly reliable results. In mechanical processing, we include main cross-section preparation methods such as "mechanical polishing" and "microtome." In ion beam processing, methods like "FIB" and "ion polisher (CP)" are also featured. We encourage you to read it.

Section preparation using a microtome! Introducing examples of observing lens coating layers and multilayer films.

Lenses for glasses, cameras, and other devices are coated with various layers. In the case of glasses, multiple coating layers are applied, including a hard coat to protect plastic lenses, an anti-reflective coat to reduce light reflection, and a UV coat to block ultraviolet rays. These layers are applied as extremely thin films, so we observed their structure in cross-section. When observed with a scanning electron microscope (SEM), it was noted that a hard coat/multilayer film is applied on top of the lens substrate, and in the multilayer film, SiO and Nb films are alternately stacked. [Overview] ■ Cross-section preparation method - Prepared with a microtome - The lens removed from the frame was cut into small pieces and embedded in resin - Subsequently, a cross-section was prepared using a microtome, followed by optical microscopy observation, SEM observation, and EDX analysis. *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
