Step down converter PCB
One side of the resistor is connected to the mounting pad.  Bridging the gap electrically would not be a problem as they are already connected electrically.  Bridging to the pin above the mounting hole may be a problem as the pin is not connected to the resistor on this side of the board.

Mechanically though this will eventually become a problem, cracking solder, perhaps cracking the resistor.

Two things you might consider:


Replacing the resistor with a leaded resistor and gluing the resistor to the board some distance away from OUT-.  This may prevent cracking of the resistor.
You might want to use a nylon washer to make a softer connection to the mounting hole.  This may ease some of the mechanical stress to the solder pad.




It may have been the intent of the layout to use the mounting hole as a way of wicking heat from the resistor to the structure mechanically connected at that mounting hole.  As stated elsewhere this has been designed poorly.

Always keep in mind with these evaluation boards that they are not designed for production applications.  They are designed solely for evaluating the performance of the electronics on the board.  And users are expected to produce their own board design that makes sense in their application.
