    I'm trying to remove a processor off of a circuit board that's inside an instrument cluster. Its a 128 pin or there abouts. I can't accurately count them because off all the "chip-quik" on the pins. I followed chip-quik's instructions, added the flux to the pins then applied the chip quik solder and spread it over all the pins. I did this on all 4 sides.

    I ran the solder iron around the sides to get the chip-quik in a molten state but when I pull on the chip or try to push it off the board, it acts like its still stuck. It had this blue rubber coating on the pins but I got that off with some acetone. I assume this blue coating is also underneath the IC chip.

    Any ideas on what to do here ????
