Ok, cool. There are plenty of soldering tips and tricks on eBay. Basic ones are to:

Tin the tip of the soldering iron

Wipe down on sponge or similar between uses to remove excess

Touch both surfaces (in this case, the prong of the switch leg and the metal ring of the hole in the Pine64 board) at the same time to heat them up to the same temperature before applying solder (heating just the switch leg or just the metal ring won't help anyone, both surfaces need to be hot for the solder to bridge the gap and flow between them)

And: don't hold the soldering iron to the printed circuit board for too long. Metal traces heat up quite quickly and you can cause damage to the board if you just hold it there for ages. 

So, summary: get the soldering iron tip hot, tin it, hold to the join (switch leg and pcb ring), apply solder, remove soldering iron tip and wait for solder to set.

hi @SkairkrohBule,

thanks for all the advisement — however, i have no idea what the phrase "Tin the tip" means in soldering?

best,
