Help with modding Mayflash fightstick

I am modding a fightstick for the first time and while desoldering the old wires from the pcb, two of the tiny metal plates fell off so it looks like this…

. Will i still be able to solder the buttons to them or do I need to get a new PCB?

You can still solder to it if you scratch the traces along the line that follows it with an Xacto knife, then solder the exposed metal.

What he says^

And you can solder from the opposite side as well
