This is the layout on the psu I did.
There are contacts on the bottom side as well.I soldered power and ground on both sides for my field supply ,I didn't use the small pins on the bottom side.
The solder flowed really easy on the long contacts,The small pins are kinda tough to solder.Just use a tiny bit of solder on the pin and the resistor.make sure you don't flow on to the other pin traces.
Don't apply to much heat for too long ,or the copper trace will start to separate from the board.
