Eds analysis providers in US 2021? The desired chip packages were sectioned from the larger board, and placed in an epoxy mounting cup. The epoxy was mixed and allowed to harden. The resulting epoxy puck was cross sectioned and polished. The epoxy mounting and cross sectioning process gave precise, perfectly preserved cross sectional surfaces through the desired components and their solder bonds.
The SEM was used to examine the crystal morphology, and the EDS spectrum showed primarily carbon and oxygen, with small amounts of nitrogen and phosphorous. This indicated an organic material as the primary component. Because the SEM-EDS analysis showed the material was primarily a carbon based organic crystalline material, a Fourier transform infrared spectroscopy (FTIR) examination was performed on the suspect material. This analysis provides necessary information about the functional groups of the organic material in order to identify the unknown organic.
Examining the sample with a polarized light microscope (PLM), it was darker and coarser than expected for a mold sample. The dust appeared to be a closed cell, synthetic blown foam material, and all from the same source. The black color was likely due to pigment particles added to color the foam. Fourier Transform Infra-Red spectroscopy was performed on the foam particles. The spectrum showed a mixture of spectral features, associated with vinyl acetates, polyurethane, and cellulose or other sugar-like polymers. Based on these features, a common urethane acetate foam was determined as the likely source material.

SEM is a powerful surface microscopy method which allows for high resolution images to be obtained on a wide range of samples. A focused beam of electrons sweeps across a sample surface and an image is created from the scattered electrons. The electron beam allows for the accurate imaging of features below the resolution limit of visible light. The acquired pictures retain good depth of field, resulting in excellent three-dimensional images. Variations in beam parameters can be made in order to highlight variations in density in the target sample, show extremely fine surface features, and illustrate texture in sample surface coatings. MicroVision Labs has multiple fully-operational SEMs, Bruker X-Flash EDS detectors and mapping technology, backscatter electron (BSE) imaging, and large chamber capabilities. These provide a full suite of microscopy services for all of your analytical needs. Explore extra info at https://microvisionlabs.com/.
