I am trying to replace a 22 pin surface mount IC on a piece of Panasonic
video quipment. I have all of the leads unsoldered but now I find that
the IC is stuck to the board, maybe intentionally. It doesn't appear to
be just the circuit board coating. It's more like the whole bottom
surface is cemented.
I would appreciate hearing from anyone, off line, who has experience in
removing a stuck IC from the board. I have tried flux removerand 91%
Isopropal Alcohol with no luck. I hesitate to force it or destroy the
chip since there are traces running beneath it. Any ideas of a safe
solvent or another way to unstick this thing?
