Cross-section making method

Abstract

The invention relates to a cross-section making method. The method particularly comprises the following steps that 1, two organic glass plates of a cuboid structure are prepared, and 502 glue is prepared to serve as an adhesive; 2, a measured object is taken as a sample; 3, one piece of organic glass plate is placed on an operating platform, and the adhesive is dropwise added to the center of the organic glass for the first time; 4, the measured object is placed on the organic glass on which the adhesive is dropwise added; 5, the adhesive is dropwise added to the measured object for the second time; 6, the other piece of organic glass is placed on the measured object in a press-fit mode, and the two pieces of organic glass are adhered into a whole to form an initial blank of a section; 7, the initial blank of the section is ground till the observation position is ground. According to the cross-section making method, the time of the whole process is greatly shortened, the making cost is greatly reduced, bubbling cannot be generated, and the section success rate is high.

Description

Technical field [0001] The invention relates to a method for making metallographic slices, and belongs to the technical field of quality control and failure analysis in the manufacturing process of a soft-hard board. Background technique [0002] Metallographic sectioning, also known as sectioning, cross-section, x-section, is a sample preparation method in which the sample is wrapped and sealed with resin liquid resin, and then ground and polished. The inspection process includes sampling, solid sealing, grinding, polishing, Finally, provide topography photos, crack layer size judgment, or size and other data. It is the most commonly used sample preparation method to observe the cross-sectional structure of the sample. [0003] The current section production usually uses liquid resin sealing glue; the current acrylic resin and curing agent are prepared in a ratio of 5:1; the curing process takes 40-60 minutes; the entire section from sampling to microscopic analysis requires at l...

AI Technical Summary

Problems solved by technology

[0003] The current section production usually uses liquid resin sealing method; the current acrylic resin and curing agent are prepared according to the ratio of 5:1; the curing process takes 40-60 minutes; the whole section takes at least 2 hours from sampling to microscope analysis, and the analysis time is relatively short. Long, can only be applied to failure analysis, but not to process first article control

If there are air bubbles in the sealing process, it will affect the observation results, and the sealing must be re-sampled; the sealing materials and crystal base materials are expensive, and the cost of slicing is high
