  Hi,
  
  I had to desolder the LCD to check continuity, as I was getting NONE with it soldered in, and in doing so I destroyed the 6th pad (from left to right) out of the 16 pads on the board. Just one side ripped out, that one side is now on the header pins connected to the LCD...
  
  Would you cut/scrape the trace just above the destoyed pad, and connect wire to the pin of the LCD and the other end along the trace? There's no pin to make a jumper wire to, unless maybe i scrape where the end of the trace is and solder a jumper wire there... I'm not sure. I've never attempted a repair like this..
  
  Should I try a conductive pen? Conductive film adhesive? Cut along the trace and solder wire from the LCD pin to the trace?
  
  Any tips would be much appreciated! I should have not left the plastic on the header pins like others have....that did not work for me!

Solder a wire like this:



On a Nava I repaired for somebody else there was a similar problem (but other trace than in your case). I attached a wire like this:



I carefully broke out a tiny piece of the IC socket around the leg where the trace ends and soldered the cable to that pin.

Thank you for the input!

Good thinking with the socket cutting. I will give this a go tomorrow
