Board edge connector track repair

I'm repairing the control module for an Ariston clothes washer/dryer, which has had arcing on one of the contacts on a board edge connector leading to the motor's stator. The arcing has removed the copper back to the contact point. What's the best way of restoring the contact? I thought about removing a few mm of PCB so the connector sides further on... any other tricks?

This track connects to a triac (BTB12), which measures as conducting in both directions to/from the gate, 30 oms and 35 ohms - I'm guessing this is about right? It's non-conducting in both directions on the current path, as expected, having not been triggered. So I think that's ok.

guessing

that's

Back in the 60's L. M. Erricsson x-bar used single sided pcb's which had a gold flash edge contact clip in placed of etched edge connectors. It folded over the edge of the board and was riveted or clipped (fold-over tab) through the board to fix it. All it had to do was overlap the copper track where it was soldered. I am sure I still have a few on hand.

One off? If so then hardwire it. Chances are it is not worth repairing.

Thanks to Ross sending me one of his edge connectors, a machine that's still worth $500 isn't going to the trash. It's nice to have a win, especially when a nice guy helps you!

I put 2 in the package so you should have a spare :-)
