To remove capsulation I used this small yet powerful Tesla coil.
After about two hours (yeah, too much time in my opinion) I managed to remove epoxy from Atmel's Attiny85.
There are few problems with this aproch:
- First the output coil gets real HOT just after few minutes. So I had to let it cool down.
- If you get the chip to close to the flame it burns get too hot if its too far away nothing happens
- Fumes are terrible
- Radiation is illegal
