Flexible electronics have attracted a lot of attention and investment by major companies in recent years due to their potential for new device form factors and use cases. Typically, these electronics are inspected during production through mechanical, electrical, and camera-based testing, which cannot always detect defects such as delamination prior to failure, nor always detect root causes of failure without further destructive testing. In this talk, we introduce a new flexible electronics inspection technology based on Optical Coherence Tomography (OCT), a non-contact biomedical imaging modality typically used in the ophthalmological space, to provide micron-scale cross-sectional imaging of devices on manufacturing lines. We also demonstrate the utility of OCT by showing inspection results of multiple flexible and inflexible electronic devices and revealing failure modes non-destructively.
