Case study of electrical short caused by conductive carbon particle in package

Carbon particle is not able to be detected by X-ray, so it is always a challenge to find out the defect mode if caused by conductive carbon particle in package. A non-destructive, quick and precious fault localization method with lock-in thermography (LIT) was demonstrated and follow up physical ana...

Description
Summary:Carbon particle is not able to be detected by X-ray, so it is always a challenge to find out the defect mode if caused by conductive carbon particle in package. A non-destructive, quick and precious fault localization method with lock-in thermography (LIT) was demonstrated and follow up physical analysis (PFA) was performed. Consequently, conductive carbon particle was confirmed as the root cause of short circuit between two failure pins.
