Replace DS Lite CPU

What tools do you need for replacing the CPU on a DS Lite, and wich ways can be used to pry off the CPU ? I'v got 3 motherboards with (blackscreen) bootup seems their CPU aint good. I'v opened them by desoldering the 4 slot1 contacts and bend it up a little. After pushing it hard back into place 1 board began to works again.

For the other 2 i can't say this. Maybe the CPU is toasted ? I cant get them to work (yet)

Please Advice! wich ways is the best for repairing the CPU and what tools do you need?

Thanks!

Hi dbnijmegen, sometimes it is good to have a schematics of the board, and check if there is voltage supplying to the CPU.

e.g. certain power management chip, etc.

the cpu i believe is a BGA, which replacement can be difficult without proper tools and skills.

you need a rework station, e.g. hot air, bga rework station infrared to remove it.

and resoldering ... those bga balls need to be in place.

Hello Augustine, Thanks for your reply. By testing out all problems i figured out it must be a bad CPU Since i got 1 back to work. i figure, would there be a way without this station. ex. by a heatblower ? one cpu only needed a little more pressure on it. i think the same problem is for the 2 other motherboards, but i cant get them to work by supply some extra pressure to it.

So either 1, i need to find another possible way to make sure the cpu is attached proper.

or 2: i need to replace whole CPU cause its toasted. (i guess, no experience YET!)

Where can u buy this station, what does i costs, and also i need something to pull it off and put it back on it ? How you soldier it back on ? also with the BGA station?

Thanks! Dennis
