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?
Hi Roy,
are you sure it is cemented? Maybe it is an 'exposed pad' pad for thermal purposes. Take a look on Google how to handle.
