How to reinforce this through hole joint with a ripped pad?
« on: March 04, 2025, 12:40:35 am »
I ripped off this trace trying to solder this pin back. Any advice on how to reinforce this pin that has alot of mechanical stress to the through hole when the trace has been ripped off?

Copper or Bronze PCB Rivets. You can get them from .8mm to 5mm inside diameter.

Do not bother with the pad, use neutral silicone adhesive to hold the part in place instead.

When you pull or push the connector, the pin will come loose again, silicone won‘t hold it back.
Stabilize the pin on both sides with good epoxy glue e.g. JB Weld

Will uv glue work or use epoxy instead?

  • Epoxy is better in this application, but UV glue should also work.
  • Use a jumper wire soldered on one end to the pin, and the other end to another component pad on this PCB trace that was lifted. The wire will serve as a flexible backup to the trace, so even if things move, the pin will still be electrically well connected.
