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.
