Is it possible to replace the chip with a soldering gun?

Question

Circuit design

Is it possible to replace the north bridge of a nanolaptop with a soldering gun, or just a station?

Answer 1

Usually only a soldering dryer changes it.
But the lower heating is mandatory, without it there is a very high probability of screwing up the board or soldering.
Small chips can still be changed only with a hair dryer. For large ones, the uneven thermal expansion of bodies begins to affect. With all the consequences.
