Hi Guys,

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?
