ATS Failure Analysis Services
Applied Technical Services offers SEM failure analysis as a dependable method of observing and categorizing a material failure. Companies request failure analysis services from esteemed providers like ATS when their product, component, or material fails prematurely or unpredictably in its service environment. Our failure analysis division uncovers the root cause behind the failure and suggests remediation steps to prevent it from happening again; our clients trust us to do these things because of our expertise and sterling track record in the failure analysis field.
How SEM Applies
Scanning Electron Microscopy, commonly referred to as SEM, produces a vivid image of the sample’s surface magnified anywhere from a few dozen to tens of thousands of times. ATS’ failure analysts use our Hitachi S-3700N scanning electron microscope to take these microscopic images. Our advanced large-chamber instrumentation allows us to accommodate sizeable samples without having to section them, to measure features as small as 0.1µm, to utilize our energy-dispersive X-ray spectroscopy (EDS) unit for elemental identification, and to produce images in stunning resolution for in-depth analysis. SEM represents an invaluable tool in our failure analysis repertoire because it can help our experts identify and predict failure modes by assessing microscopic features, such as:
How the Method Works
SEM, as its full name implies, makes use of the surface material’s electrons to build its image. The process begins with an analyst introducing the sample to the instrument’s specimen chamber by securing it to the stage. When the chamber is shut and evacuated, they energize the filament that produces primary electrons. Focused through a series of electromagnetic coils onto a small sector of the specimen, the resulting beam of electrons will bounce off the sample’s surface, generating both the secondary and back-scattered electrons used for imaging, along with characteristic x-rays used for chemical analysis.
Frequently Used Standards
Our technicians bring cumulative decades of experience performing failure analysis methods to relevant standards. While these experts can conduct SEM-assisted failure analysis according to client specifications, they execute the method in compliance with the ASTM B748 and ASTM E1508 standards most regularly — both of which we maintain ISO 17025 accreditation through the A2LA to perform.
