Abstract

Here, we demonstrate how electro optical terahertz pulse reflectometry (EOTPR) can be used to quickly and non-destructively isolate faults in 2.5D packages. We present case studies to show how EOTPR can unambiguously differentiate between faults located in the C4 bump, TSV, RDL, and micro-bump of a 2.5D package.
