JAMMA edge connector pin lifted

[Wraith]

How should I fix this

It was black/charred when I bought it from SNK** but now the pin thing is lifting up and is all black underneath of it. I think it’s the +5v pin

Edit: lol, meant SNK, not RGB

You could try and clean the charred area underneath the pad and then glue the pad.

It was black/charred when I bought it from RGB

btw, I have never owned or sold the CPSIII, this must be some misunderstanding.

There is what looks like a solder bridge between +5 and one of the GND pins causing a short which is why it's burning up. Stop using the board immediately and get someone to clean it up for you properly.

You will cause a lot of damage running it any more so please don't.

There's no solder bridge. It's just light reflecting from the charred PCB.

You really want to try glueing the track down like @RGB said. The problem is that when inserting the jamma connector the lifted track can fold over the neighbouring ground track and then you'll have a bridged connection between 5V and GND.

How does one fix it

The proper way to do it would be to:
-remove the original pad and coating over the near by trace
-clean the PCB super well,
-cut a new pad and trace from a copper or gold sheet
-lap solder the new pad onto what's available of the trace
-epoxy the pad down
-clean again
-epoxy over coat the exposed trace

or if it were me I'd just
-clean the PCB super well
-epoxy the lifted trace part
-clean again

to get it started grab some IPA and a toothbrush and just lightly clean the area. That would let you see the damage and/or bridging a bit easier.

Ok it snapped off, but everything seems to be ok. Is it ok to leave partially broken off?

 

[nem]

It's fine. There's three other tracks for 5V.

Ok. I still have the copper piece that broke off but just not sure of super gluing it back in place was necessary
