Technical Concept

The principle of THEMOS is to use highly sensitive InSb detector to sense the heat radiation generated from faults.

The compact and easy-to-use THEMOS mini is a novel non-destructive EFA tool used for fault isolation. It holds an impressive advantage of decapsulation unnecessary when inspecting failures via either the frontside or backside of IC devices.


The principle of THEMOS is to use highly sensitive InSb detector to sense the heat radiation generated from faults. Based on the heat distribution, the location of “hot spot” can be identified not only in x-y plane but also in vertical axis with thermal-transport-related calculations. Therefore, THEMOS is a powerful FA tool for stacked die packages. It can be applied to FAs for ICs, packages, PCBs, panels, passive components, etc.
