Jerry, I'm having trouble imagining how the traces could have lifted during
normal installation of a resistor. Really excessive soldering iron temperature
is the only thing that comes to mind. Did you use a fine-tip,
temperature-controlled iron? A PC-board defect (copper traces not firmly adhered
to the board) is theoretically possible, but I've never seen a case of this myself.
In any case, if the traces just lifted a very small amount and are still making
contact with the other circuits, you should be OK. If the traces are broken,
you'll need to add short jumper wires as needed between the leads of R15 and R16
and the places they need to go, i.e. 5 and 12 of U1, and to ground and 5V. Refer
to the schematic.
73,
