Decapping and looking inside a USB isolator IC [Hacking]
posted October 9 2014 18:34.35 by Giorgos Lazaridis

Lindsay followed a tutorial from Ben Krasnow. Ben used fuming nitric acid to remove the plastic cover and reveal the heart of a chip. Lindsay used normal concentrated acid with the chip placed on a hotplate at 120oC and worked like charm.

The victim was the Analog Devices ADuM4160 USB Isolator. The company claims that the isolation is done with transformers embedded in the chip. Check out what Lindsay found inside!

Here is a video from this hack
