Hello, I have very small experience with soldering and i was working on this board and was gonna remove a chip to code it. But after opening it up and looking at the board i saw it has been worked on before. And over the chip im removing it has a blue film/glue. I have no idea what it is or how to remove it. Im removing the small 8pin chip.
Is it safe to just use hot air to remove the blue stuff+chip?
THanks in advance.
