I found a hint in the Qualcomm specification "GPS Quality, 19.2 MHz, Crystal, and TH+Xtal". Laser tuning a capacitor would have been quite strange. We also offer a range of versatile tools, where our Thermo Scientific Prisma E and Thermo Scientific Quattro SEMs are the ideal choice if sample flexibility is a priority as you can image a sample in its natural state.I have generated an area for quartz, oscillator and similar parts: By the way: Now I know what the strange part under the quartz of the u-blox SARA modem is! Thats a NTC to check the temperature! Now the laser tuning makes sense. Within the field of material science, Thermo Scientific Axia ChemiSEM is a flexible, easy-to-use SEM EDS instrument, which provides instantaneous and quantitative elemental analysis. The Phenom Perception GSR Desktop SEM also provides SEM EDX gunshot residue analysis. Our ParticleX range, for example, targets specific chemical analysis applications, including Phenom ParticleX Steel Desktop SEM, Phenom ParticleX TC (Technical Cleanliness) Desktop SEM, and Phenom ParticleX AM (Additive Manufacturing) Desktop SEM. For each sample, the right combination of settings is required to optimize the results of your analysis.Īt Thermo Fisher Scientific, we provide a vast range of SEMs, many of which are tailored to specific sample types. SEMs are versatile instruments, which are capable to analyzing a vast range of samples and materials. However, the Phenom Pharos SEM features a field emission gun source, and is capable of resolutions below three nanometers. Our Verios SEM is capable of a resolution of 0.6 nanometers at 30 kV, for example, and our Apreo SEM is capable of 0.9 nanometers at 1 kV.Ī desktop SEM can typically achieve resolutions of tens of nanometers. Some SEMs are even capable of sub-nanometer resolutions. Typical floor model SEMs can achieve resolutions of the order of 1 to 20 nanometers. 100 nanometers or higher – suitable for quantitative compositional analysis.Three nanometers – suitable for analysis of microstructures.Two nanometers – suitable for micro- and nanoscale characterization of topography, composition and phases.Less than one nanometer – suitable for nanoscale characterization and manipulation of nanostructures.Resolution also affects the available applications: SEM resolution is an important consideration because an instrument’s cost and complexity will increase with its resolution. SEM resolution can be anywhere between less than one nanometer and up to tens of nanometers. Let’s look at some key considerations now.Īn SEM can achieve sub-nanometer resolutions and magnifications and depths of field up to 300 times better than an optical microscope. Your choice of instrument often comes down to your target applications and your current facilities. There are plenty of SEM options available. Many use automation and other intuitive user interfaces to provide a solid user experience. Modern SEMs are optimized for high throughputs, ease-of-use and measurement consistency for your quality control and fault analysis applications. If your SEM includes a broader range of detectors, you can also reveal a sample’s molecular composition (Raman), impurities and optical properties (cathodoluminescence) and crystallographic information (electron backscatter diffraction). They also provide comprehensive information, helping you to analyze the morphology, topography and chemical composition of your samples with ease. SEMs provide higher resolution and magnification and a better depth of field than an optical microscope. Today’s SEMs are superior quality control and failure analysis machines, compared to their predecessors and optical microscopy tools.
