There was a 15" that would burn up the vert board with
those connectors. Other than that I remember a few other
cracked ones but they still made good contact. If you have a
trouble maker maybe pull it & epoxy it. You could also build up the
solder on the connections but that may spread it out more.
Best cure is good NOS if you can find some.
