    Quoted from ChrisHibler:

    The corrosion looks like it's limited to the parts and didn't invade the traces. I've never seen a board with so much corrosion limited to parts only.
    Still...if it were my board, I'd take a shot at it. But, I repair boards all the time, and if I don't get all the corrosion and it comes back, not big deal for a board in my game. I wouldn't take it on for a customer. Too much time, cost, and risk of corrosion returning.
    PS - I like your shoes too.

    I think this means the corrosion happened recently. I have seen some leaks caught within a month or so of the puke end up looking worse than it is. More typically the battery damage happened years ago and the corrosion goes deep down.

    I would pass on fixing that board. Hard to say how it is going to look once you pull those PIAs on components. SYS 11 boards seem to be a nightmare if the batteries leak. They dont hold up to an abrasive cleaning like the earlier generations did.

    If the solder readily sticks to the trace, you have removed the corrosion. If the solder does not want to stick to spots and the area turns dark colored, it needs an abrasive cleaning.

    I abrasively clean the traces down to clean solder or clean copper. If the battery damage is severe, it is possible it has corroded all the way through. I always solder tin abrasively cleaned traces.

    If a trace is blown out and the gap is small, i use a resistor lead or something appropriately sizes to bridge the gap and tack it down to the trace. Other times a fine wire appropriate. I try to avoid using long wire runs if all possible.

    Your work is looking pretty good so far.
