Failure analysis
Virtue arises from necessity
Since the very beginning, assessing and improving reliability have been the driving forces in Nanotest's work which included non-destructive failure analysis very early in the process. All failure analysis tools that enrich the Nanotest portfolio, today, are fruits of this long journey and implement nothing less than years of theoretical research with academic partners and practical experience in cooperation with the industry.
Method of choice
General method used for thermal imaging-based failure analysis
Thermal excitation of a surface (usually by optical sources such as flash lamps or lasers) leads to a thermal wave traversing the deeper layers of the sample under examination. Different methods allow to set the focus on different thermal phenomena, flaws and materials. Our toolbelt, mostly based around our failure analysis system TIFAS IR Lab is well-equipped with all methods necessary to conduct fast and highly resolving failure analysis at state-of-the-art industry samples.

VacBlack® - emissive coat without coating
For best results in thermography, high emissivities are at least beneficial, sometimes even inevitably necessary. While usually applying camera paint or other emissive coating, in non-destructive testing, also surface coating is a no-go. Our solution is a residue-free, removable temporary coating system called VacBlack.
- Temporary lamination of the specimen with a high-emissivity foil to improve infrared analysis.
- Suitable thermal attachment between foil and specimen by vacuum.
- Residue-free removal of foil after sample examination.
- Fully integrated into TIFAS IR lab system.
- Two types of VacBlack® – foils: 50 µm & 30 µm thickness.
