Abstract

The invention provides a sample preparation method for normal EBSD analysis of an electronic aluminum foil for an electrolytic capacitor. The sample preparation method comprises the following steps of: sampling and inlaying; mechanical polishing; vibration polishing; electrolytic polishing; and resin dissolving. The method of the invention can obtain a high-quality sample test surface meeting therequirements of EBSD analysis conveniently, quickly and accurately, and the qualified rate of samples can reach more than 90-98%, so that the method is suitable for the detection and analysis of normal plane grains of the electronic aluminum foil for the electrolytic capacitor, lays a foundation for the study of the correlation between grain orientation, grain boundary characteristics, long and short corrosion holes and the specific volume of corrosion foils, and provides support for the study of the relationship between the crystal properties of the electronic aluminum foil for the electrolytic capacitor and the comprehensive performance of products.

Description

technical field

[0001] The invention relates to the technical field of detection and analysis of electronic aluminum foil, in particular to a sample preparation method for EBSD analysis of electronic aluminum foil used in electrolytic capacitors. Background technique

[0002] Electronic light foil is a high-end aluminum foil, which is mainly used for aluminum electrolytic capacitors, which are important components in the electronics industry. With the rapid development of the electronics industry, the performance and integration of electromechanical products are getting higher and higher, and the requirements for electronic components are also increasing, and higher requirements are also put forward for electronic aluminum foil. During the corrosion process of electronic aluminum foil, with the growth of holes, it will encounter matrix defects such as vacancies, dislocations, impurities and grain boundaries. These defects will obviously affect the growth of holes, resulting ...
