Description
Technical field
The present invention relates to electric aluminum foils to test and analyze technical field, more particularly, to a kind of electrolytic capacitor electronics
The sample preparation methods of aluminium foil normal direction EBSD analysis.
Background technique
Electronic light foil is high-end aluminium foil, is mainly used for the Important Components aluminium electrolutic capacitor of electronics industry.With electronics
The rapid development of industry, the performance and integrated level of electronic product are higher and higher, require also increasingly to increase to electronic component, equally
For electric aluminum foil, higher requirements are also raised.Electric aluminum foil is in corrosion process, and with the growth of hole, it can encounter sky
The matrixes defect such as position, dislocation, impurity and crystal boundary, these defects can significantly affect the growth of hole, cause the holes such as short-bore, side opening
Defect reduces the area expanding rate of etched foil, finally influences specific volume, and wherein crystal boundary is to influence its hole to grow most important factor.Electricity
The research of sub- aluminium foil normal direction crystal grain is significant to control electric aluminum foil section number of grain boundaries and grain boundary features, passes through different systems
The fractograph analysis for spending light foil, can observe directly the section crystal grain and orientation information of sample, to analyze section crystal grain
Control mode, it is significant for improving the long short-bore of etched foil, promotion etched foil specific volume, it is the weight of electric aluminum foil technology analysis
Want means.
Currently, there are many existing technologies about crystal grain analysis of electrolytic capacitor electric aluminum foil, wherein spar degree method
It is a kind of indirect method for measuring cubic texture in aluminium foil, since the corrosion resistance of cubic texture is good, table after coarse micro-grain sample etch
Face is in the matrix of white light tone, by measure white spar body number come indicate cubic texture number, it is anti-corrosion using aluminium foil crystal face
Property different principle, the detection of aluminium foil cubic texture is carried out with simple chemical corrosion method, the method is simple, but quantitative accurate
Property it is low and need certain experiential basis.Etch pit method is that have the place of dislocation under the conditions of specific etch using test check face
Preferential corrosion generates dislocation etch pit, and the texture of crystal is orientated where the shape of dislocation pit will depend on it, is counted by etch pit
Can be determined that the texture orientation of crystal where etch pit, the method is simple and can quantify, but the influence factor of quantitative result compared with
It is more, such as sampling method and operation technique etc..Electron backscatter diffraction (EBSD) technology is existed based on electron beam in scanning electron microscope
The analysis of diffraction Kikuchi band that inclination sample surfaces excites and formed, and then determination crystal structure, orientation and relevant information side
Method has important role in the tissue characterization of crystalline material and analysis.In electric aluminum foil material, EBSD is mainly used for taking
To analysis, the analysis of micro- textile analysis, crystal boundary, grain size measurement etc., since backscattered electron only occurs in tens, sample surface layer
The depth bounds of nanometer, and EBSD technology needs to tilt the viewing surface of sample into 70 degree, and by electron beam in viewing surface
It excites and forms diffraction Kikuchi and bring and analyzed, sample viewing surface is required very high, sample preparation procedure difficulty is big.It is existing
There is technology CN106504251A to disclose a kind of electric aluminum foil cubic texture detection method of content based on picture processing, the technology
In aluminium foil cubic texture content is measured using spar degree method, by the number of pixel shared by the aluminium foil that extracts of statistics with
The number of pixel shared by the non-cubic texture extracted obtains content of the cubic texture in aluminium foil, instead of traditional artificial
The method of observation determines cubic texture content, and the problem that unresolved dosing accuracy is low.How crystallography side is comprehensively used
Method analyzes this technical problem, and there are no refer to that electrolytic capacitor electronics aluminum foil method analyzes to EBSD in existing technology
Method.
Summary of the invention
The technical problem to be solved by the present invention is to overcome existing electric aluminum foil crystal grain analysis method dosing accuracy is low, lack
It falls into and insufficient, a kind of sample preparation methods that electrolytic capacitor electronics aluminum foil method is analyzed to EBSD is provided.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of sample preparation methods that electrolytic capacitor is analyzed with electronics aluminum foil method to EBSD, include the following steps:
S1. it samples and inlays: sample being carried out to inlay solidification with epoxy resin；

Light；
S5. dissolving resin: epoxy resin is inlayed in dissolution, obtains final sample to be tested.
Wherein, fixed for convenience and hold and take, sample of the invention can be taken to cutting box-like size, preferably 30mm*
50mm。
It is washed using water as cleaning agent after mechanically polishing SiC water sand paper polishing in S2.
Electrolytic capacitor electric aluminum foil will often analyze the depth and etched foil ratio of corrosion hole in research and development and production
The relationship of appearance, and corroding the depth of hole and electronics foil normal direction crystal grain quantity, grain boundary features, crystal grain defect has close pass
System, the signal of EBSD come from specimen surface 10-50nm depth, and the more high effective information collected of specimen surface finish is just more
More, style is more clear, can obtain clearly EBSD Kikuchi style using method of the invention.
Sample preparation methods of the invention are easy to operate, realize easily and fast, accurately obtain electrolytic capacitor electricity consumption
The sub- comprehensive crystallography information of aluminium foil, analysis corrosion hole depth reason, while being but also widely used for the processing procedure prison of electric aluminum foil
Control, Improving The Quality of Products.
It can get the bright and clean pollution-free, non-oxidation layer of specimen surface, without surface stress using sample preparation methods of the invention
Sample, it is convenient, fast, accurately obtain high quality meet EBSD analysis require sample examination face.
