Hi, if you can, it is far easier to design around the problem and eliminate the need. One example method is to use ferrules:

Although ferrules are better on stranded wire, they still work with solid core wire to make electrical contact. Ferrules are also way cheaper (they cost a penny or so) and less time-consuming than special flux and soldering.

And then you can solder the crimped ferrule onto the PCB, and 'do something' with the wire for strain relief (could be as cheap as drilling an extra hole in the PCB to pass the wire through. Or use screw terminal blocks, with or without ferrules.
