Aside from Bruce's comments, I would add that you
need to make sure there is
no stress placed on the trace after soldering. The bond strength of the
copper to the laminate is not very great, and it is quite possible to pull
the trace off.
You may have to scrape the solder mask off to get a good connection, use
minimal heat. When done clean well and it's not a bad idea to put a drop
of epoxy on the area and maybe the back of the connector (where the pin
goes through the board) to support it.
