So... the top pads are no longer attached??? They came completely off the
PC board?
One of the pads is ground, which can just as easily be soldered and
connected to ground on the bottom of the board.
The other lead is DC, and it has no connection on the bottom of the board,
BUT the pad on the bottom of the board CAN stabilize the cap once it's
installed.
What I think I'd do is to solder a thin (BARE) wire, say something on the
order of #24, maybe #26 to the POSITIVE lead of the cap, right up against
the bottom of the capacitor case and in a physical position which will
enable it to exit from under the cap so it will follow the land, or what's
left of it.
Then, some short distance from where the cap will mount, take a sharp blade
and scrape away about 1/4" of the green solder mask from the remaining
land. Tin the land.
Then, insert the cap into its holes and solder in place. Finally solder the
wire to the land.
Good luck,
