Hi Guys.

Do you think this board can be saved?

Hi,Rewire...,
just be sure where the trace go...and rewire...,look for the most fine cable.

 Hi Costa !

Of course it can be saved. Carefully scrape off the corrosion with a tiny flat head screwdriver, wash off the residue with isopropyl alcohol and put some fresh solder on the exposed and cleaned traces. Once finished, test for continuity. If everything is good, you can even apply nail varnish over the repaired area to make it even more corrosion proof.

P.S. There will be times when you will want to repair something more fragile, let's say a keyboard membrane. In such cases conductive glue should be used.

The two wide traces under the battery wires are easy.

I am really concerned about the bus that run just below the blue wire to the central CI.
I have tested already for continuity and several of them are bad.

... and they are really thin!

 Hi Costa !

The same principle applies to tiny traces as well. Only this time you will need a digital microscope.

I got that one already!


Let´s see, hope I don´t have to do that.
