Use a soldering iron with small chisel tip end, 2-3 secs heating copper pad and then flow a small amount of solder onto each pad in turn. If you do not overload the solder it will only flow to the edge of each pad. (Using a small amount will ensure you have just enough to flow when you come to the next part of the process) Then make sure you tin each wire prior to offering up to the relevant pad (do not make you bare wire ends too long - 2mm is more than enough) and make sure you offer it straight onto the pad to avoid possible shorting between wires.) Then before you apply the iron, apply a very small amount of solder to the tip, then apply to the wire sitting on top of the soldered pad. They should flow fairly quickly, remove tip and move onto the next one !!
