Greetings everone,
Ide like to report here about our small, ongoing journey about repairing the Amiga 2000 Mainboard from a leaking battery.
Let that said we are not even Semi Professional soldering people. We are hobbyists trying to save Old Hardware from dieing.
We sure are open to any hints you can give us.
We recently aquired a Amiga 2000 knowing it has a leacking battery and most likley damaging this machine for many manny Years.
Knowing that a big chunk of work awaits we decided to give it a go.
We made a Video of the first First Aid Actions we took cus of the Battery Leackage. As you can see we stopped where we neutralized the most of the alkaline. (I know i say Acid in the video but thats a german thing, its called "Batterie säure" in german wich is translated as Battery Acid)
The Alkaline transformed the Solder into some strange metall alloy that was Resistant to any Heat we applyd (up to 450 C) and making unsolder the Attacked parts really hard.
If one of oyu might know the chemistry behind that i sure would love to hear it!
As you can see the Shiny solder turned into some Grey matter
Now we scrubbed up the solder mask with a special brush made out of fiberglass to take away all the damaged coating.
The damage of the Battery Liquid was crawling all trhough the CPU socket. As you can see a few traces got lost in the process as they where too damaged
We now replaced also attacked Capacitors and joined ...not really professionally but working, the traces with a wire together.
Ofcourse ide like to keep you up to date here finishing this to a Part 2 of the Project to save this Computer to make another video out of it to be uploaded on our channel.
Sidenotes:
We got rid of the old Soldering Iron of part 1, it was a spare one.
The board is a 2 layer board.
UPDATE 26.july We did it! We repaired the amiga and its even working! I stated EEVblog in the video and the chemical description! Thanks guys!
