In our failure analysis lab, we investigate a material failure’s background or history of a sample, to determine why a particular failure occurred.  A product failure may include premature breakage, discoloration or even an unexpected odor. It is useful to know if this failure is a new, unique occurrence or if it has been an ongoing issue. The investigation can involve analyzing the sample as it currently exists and extrapolating from that data what may have caused the failure. A sample of the “good” vs. “bad” product may also be useful for comparison purposes.

Physical failures (e.g. poor adhesion, pull strength, fractures, discolorations) are investigated using surface analysis, materials characterization and metallurgical analysis techniques. The scenario and sample type impact which analytical technique can be used.

EAG has a variety of instrumentation in our failure analysis labs, such as Optical Microscopy, SEM/EDS, FTIR, Raman, TOF-SIMS, XPS, and Auger. We also work with experts in metallurgical failure analysis and fracture analysis to better understand the mechanics of the fracture, failure modes and origins .
