[sdiy] Need urgent help, Juno 106 key contact broken lead

Hi!

I would use conductive laquer as this is what is use for the halfmoon parts:

Sometimes you can also buy conductive laquer that has silver in it...

Betreff: [sdiy] Need urgent help, Juno 106 key contact broken lead

Hello friends.

Today I took my beloved Juno 106 out of storage to prepare it for a show. Checking the keyboard I found one dead key.
I took the keyboard, key and rubber stripe off to see what's under it. What I found was that at the very point where
the keyboard PCB trace for the certain key, meets one of the "half moon" contact, there was some kind of corrosion.

I checked the contact between the PCB trace and it's half moon, and found there was no contact between the two.
That right-hand half moon is supposed to be connected to the same line with all other right-hand half moons of all other keys.

I'm afraid to try anything before I have your advice so I don't cause any further damage... These PCB's are impossible to find.

How can I reconnect the track to the half moon and keep good contact between them ? I'm afraid soldering iron is not going to work here ?

Thanks very much for your advice !
