QUOTE(MaTiAz @ Dec 28 2005, 01:58 AM)  Hot-air rework stations are needed, and they're waaaay too expensive for everyone to get them. And stick the cpu about 1 mm too far, and you're screwed  Not just an hot air rework station, you would need a special adapter to be able to remove bga chips ( ball grid array, I think) I have been using an hot air rework station for a few years now, for replacing TSOPS etc, this takes time to master, but as you have access to the legs on the chip it fairly easy, and any cheap rework station would do the job. But the CPU is BGA like I mentioned above, and all the connections are under the chip itself, this makes them impossible to get to without specialist adaptors etc, and in my opinion, very hard to remove for the average joe blogs who only plays around with electronics as an hobby. They are fitted by using tiny balls of solder, between the chip and the mainboard, which are both heated to a high enough temperature to melt the solder. Rick P.S The above info is from memory, so if im wrong in anyway, please correct me, so I can also learn like everyone else.

Actually, I heard that you can remove BGA packages by microwaving the PCB, so it heats up and the solder melts

I finally managed to get my board out of the microwave, and all seemed ok, but now I have to restart my microwave every 5 mins, it keeps displaying a blue screen of death, and telling me to contact my vendor

You are quite correct. I use a DRS-24 for BGA re-work, (should say used, as I don't work there anymore). -nB
