nice repair, but i would have done it slightly different, the small pcb trace may or will fail eventually due to the bnc stress on the front panel, hot glue wil never be strong enough to prevent that mechanical stress, i would have put an kinda loose wire up to the smt capacitor if the pcb want to separate again
Or maybe use some kind of bracket maintained by the frame nearby
not sure if thoses bnc square casing was solderable
