Repairing a burnt board connector properly
Steps
- Pull the board. A new plug alone will burn again, because the old header pins keep their resistance.
- Desolder and replace the male header pins on the board; do not just sand and tin them, since the plating is gone and they will tarnish again quickly.
- Fit a new housing with crimp-on pins (Trifurcon for .156 inch), not insulation-displacement pins.
- Add a polarizing peg to the new housing so it cannot go on the wrong header.
