Chip Reverse Engineering

From tmplab

Microscope

Thanks to Karsten Nohl presentation at Hacker Space Fest, there's an interesting DIY approach for reverse engineering.

Features

These are the features we're looking for:

  • 500x magnification
  • 2 MP to 8 MP camera
  • Objective table to move the chip slowly (i.e. not by hand, too much shaking and imprecision)
  • Reflected (incident) lighting

Feature we DON'T NEED:

  • Confocal microscope (it seems, because we'll abrase/grind away the upper layers anyway and the bottom layers are opaque anyway too)

Perfect Microscope

Still selecting the right model.

Poor man microscope setup

  • Objective table: micro-screws controlled moving plate
  • Microscope: 640x optical Bresser (lent by Phil's friend).
  • Camera: 3.2 MP Canon Ixus V3
    • Mounting: Attached directly to the eye-piece
    • Drawback: produces round (not square) pictures (with no noticeable deformation) of smaller size/coverage than regular microscope-camera.
    • Advantage: working and free

Substrate

  • What kind of glue to use to attach the chip to solid/manoeuvrable support?
