+====== Decap ======
+Removed metal lid by bending the edges up and levering it off the epoxy. Hot air (480C at max airflow) + bending with vice and pliers to crack the plastic away from the die.
+The PCB which the die is mounted on presents a bit of trouble vs. a plastic-plus-leadframe type package. Basically keep heating, and try to make the plastic crack across the die so the plastic falls away.
+Die is located in the centre of the package, sized approx 10mm square.
+The die is polyimide coated - the plastic packaging may stick to it. Polyimide removal TBD.
