Robot Controller 12v Power Spade Pulls Out PCB

[Dale(294engr]]

Has anyone else experienced RC primary power pins pulling out ?

(our neg pulled out with spade)

We are concerned about power interruption during competition.

Rule does not permit opening the RC to properly re-solder to the printed circuit board.

It appears the two pins beneath & part of spade were soldered to the mother board and are addityionally supported by metal support in the RC case.

Are these supports electrically connected to the board ?

(i.e. can we solder the spade to these for a reliable connection ?
from outside top of RC
or may we open the RC to fix it properly)

I have a JPG pict but can't reduce it to 100k using this PC's applic to post (25%min =267k)
