I was trying to flash OpenWrt onto my BT HH5 wireless router and it involves soldering wires to very tiny balls of solder, which in the guides I've been following are referred to as pads. I've tried putting a small amount of solder in the little caveat hole but it doesn't stay in place. I known this would have been produced in a factory by a machine but is there any way I can repair the broken pad?
UPDATE
I've put a 1p coin in the corner for a scale comparison to show how small the pads really are. The blue circles represent the pad I have been referring to.
As there is a hole wear the pad was, is there nothing I can use to refill the hole? I knows this sounds stupid but is there a conductive glue that the solder can stick to?
I've been using a battery powered soldering iron, but should I be using a temperature controlled iron with a low temperature and maybe using a smaller head on the iron?
N.B I only usually solder leads for audio equipment so moving down to micro PCB components isn't too much for my hand in terms of keeping it steady, but the fact that I think I need to invest a decent soldering station possibly?
