Cross-Section Analysis

Cross-section analysis is employed whenever the internal structure of a material is of interest. It can provide a wide range of information, such as the layer structure of a plating system, the extent of corrosion sites from the surface to the underlying core materials, the 3D structure of semiconductors and PCBs, the distribution of fillers in polymers, and the core structure of powdered materials.


Before performing cross-section analysis, an appropriate sample preparation technique must be selected, as the method of preparing the cross-section can significantly influence the accuracy of the results. Traditional metallurgical sample preparation techniques, such as cutting, molding, and polishing, can certainly prepare a cross-section, but they may not be suitable for all materials. In some cases, low-temperature cleaving is more appropriate, while in others, the removal of surface materials using high-energy ion beams is necessary to achieve better grain contrast or to retain voids during failure analysis.


At ASMAC, we have extensive experience in handling cross-section analysis for various materials. We can readily advise you on the most appropriate methods for processing your samples based on your specific needs.
