I am trying to reverse engineer a product, but I ran into a problem:
One IC had a heatspreader on top of it.
With a bit of force I could remove it, but I am unable to read what's written on the IC, because there is some kind of black cooling paste on it.
It's solid - I can only scratch it with a screwdriver. But I'm afraid that I'm destroying the text on the IC.
Do you have some idea what it could be and how to remove it?
It is probably a stepper motor driver, but I want to know which.
If it could help you, I can measure some voltages or watch it with an oscilloscope if you want. The whole circuit is working fine.
- It is a DIP-16 with the Stepper motor connected to pins: 6-3-14-11
- Pins 4-5-12-13 are connected to ground.
- Pin 8 is the only other big Trace on the IC, guess that's VCC then.
I hope you can help.
