Microhardness testing services with MicroVision Laboratories, Inc. in 2021? The profile of the flow of the solder at these bonds was documented using the SEM with backscatter imaging, which correlates brightness in the image with atomic density. Some voids were found in the solder as shown the SEM image. An EDS spectrum of the solder was acquired which showed that the solder was a tin/lead (80/20) solder. The EDS map clearly shows the copper wire and copper pad (red) with the tin lead solder (light blue) that appears to have flowed well and made a good bond between the copper elements. This map also shows the fiberglass bundles that add structural integrity to the board.
Conclusion: Based on the analytical report, the client was able to demonstrate that the particles were consistent with a common aspirin tablet. When the end customer was approached with this report, they remembered that their spouse had taken an aspirin earlier that morning, and had likely used the bottle of water in question to do so. Based on this, the customer was happy, the manufacturing client was satisfied, and the sample was maintained – undestroyed should someone need to examine the sample again or do any more esoteric testing. For an affordable price, the client was able to get piece of mind, and gather information from a very wide range of testing methods quickly and accurately.
MicroVision Labs is owned and operated by a career microscopist, John Knowles, who understands the needs of our clients. Our emphasis on helping our clients solve problems, not just providing data, sets us apart from other labs. We have the technology and knowledge to find answers to your most difficult challenges, helping you succeed at every step. Can I come in to see my samples analyzed? Yes, our clients are always welcome to come in while their samples are being analyzed. For much of the work we do, it is mutually beneficial for our clients to be present to help direct their project since they can provide expertise about their samples. Some of the services we provide such as polished cross sections have time consuming steps making it impractical for a client to stay to watch everything. In those cases it is recommended that you come in initially to explain what you need done and come back at a later time to see the finished product. Read extra info on website.
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.
How do I submit a sample or a set of samples? To submit a sample or set of samples, please see the page How to Submit Samples. What if I believe my samples are hazardous? We are not equipped to handle or dispose of every kind of hazardous material. Please call us before sending in any potentially hazardous samples. In cases where we are able to analyze your harzardous samples we may not be able to dispose of them and therefore we will return them to you.
Energy Dispersive Spectroscopy (EDS) identifies the elements present in a sample by analyzing the X-rays generated by the electron beam of the Scanning Electron Microscope (SEM), making it an indispensable tool. Since X-rays are only generated from the area of the surface excited by the small electron beam, spectra of individual areas or particles can be obtained. Spectral information can therefore be generated for an entire field of view by scanning the beam, providing an elemental map. With the high count rate and excellent signal to noise ratio of our advanced QDD EDS detectors, high resolution data sets are collected and analyzed in minutes, rather than days. This elemental mapping technique allows our clients to immediately visualize the chemical landscape in their samples. Additionally, since the entire spectra is stored for each pixel, areas of interest that are identified later can be examined in detail, without ever having to re-image the sample. Other labs can’t touch the quality and visual impact of the elemental maps we produce here at MicroVision Labs. Discover a few extra info on https://microvisionlabs.com/.
