To make the cross-section of the above components, generally need to go through the following steps:
 
[1] Use epoxy resin to vacuum soak the components for fixing;
[2] Use grinding or cutting to remove the surface layer of the components;
[3] Polish the remaining part to show a clear cross-sectional image;
[4] Take photos and observe under a magnifying glass or microscope.
