BGA removal

[zerorisers]

Hello everybody. I have recently purchased a hot air rework station from frys, but I must know. what would be the best way to preheat the board before attempting to use the hot air gun to remove the BGA device? IR or hot air? I will be doing all work in a small room that is about 8"x10" so heat up of the room itself is an issue as it is a bedroom. i have about a 2.5" x 1.5" space to work with.

Thanks in advance, zerorisers.

"It depends" (on what size your BGA is and what your board size is).

With a hot air station, you will most likely not be able to control the heating of your board/BGA properly, resulting in delaminated PCBs.

I have one of these for the explicit purpose of desoldering/soldering BGAs in a prototype environment (same setup as in the picture):

I bought a yihua 853AA for this purpose
an ir plate under the board I heat to 200°C, and the hot air gun above the chip at 300-350°C depends on the size of the chip
works nice. the station paid itself already 6 times ...
