solder acros the gap if it is together. If it is a gap where you could se light through it, you will need to bridge the gap. dont use a paper clip, its not really the right metal for the job. use the copper wire (fine strand) that you use for wiring your car. strip off all the insulation, and use it to help bridge the gap. make sure you get the joint good and hot for a good flow, and when you are done, make sure no solder splatter got anywhere else on the board where it could short something out.
