Abstract :
This paper will present the non-destructive Lock-in thermography (LIT) technique and its application in detecting low-ohmic power shorts in 28 nm GPU (Graphics processing units). LIT was successful in detecting power shorts within die and package down to 5 Ohms within seconds, leading to accurate and efficient root cause analysis.
