Old A2000 board Q

[jagoche]

Got recently an old A2000 board. Which is supposed to be functional.

I cannot test it at the moment (my A2000 is not working), but visually it looks fine. The CPU and battery are missing though.

There was battery leakage before the old owner removed it, but the damage doesn't seem serious to me. CPU socket is also corroded, all contacts are green.

Please let me know if there's something that needs to be done with the board regarding (past) leakage and corrosion.

I will use the board in the future to assemble again my A2000.

I ended up with a 2000 with similar damage.  I had to desolder the cpu socket and replace it to get the computer to not randomly not start or crash.  Not an easy chore considering the traces that can right next to the pins and how easily you can burn the board if you aren't careful.

It looks ok to me. I would use a PCC (Printed Circuit Cleaner) spray, one of those that have a small brush attached to them and use it to clean the contacts on the CPU socket and anywhere else that may be dirty.

Other than that your board looks pretty good to me. I've never done it before but maybe you could put some lemon juice around the area where the battery leaked. I heard it will neutralize the acid. Don't quote me though.

I recommend using small flat screw driver (thinner the better) gently scrap off the green residue.  collect it with slightly wet qtip.  once done, use electronic spray to clean and collect anything else.
it doesn't look too bad, you might be lucky.

Thanks for your useful suggestions.

I'm curious about the lemon juice though.

I heard about this before, but cannot understand, how lemon juice, which is acid, neutralizes acid battery leakage???

I have never tried the lemon juice myself either so i don't know how and if it works. Maybe somebody else has used it?

Because the leakage is alkaline, not acid.
