hello
I bought a soldering station today , as i was having trouble heating up pads connected to ground planes.
this new one I bought is meant to get up to 450 degrees C ( definitely C not f) . so i whack it up all the way. as the reg i have is connected to a heatsink.
Beware, this doesn't say what you think it says. For stuff sinking heat the watts the soldering iron can put out is important, plus how good the temperature regulation actually is.
If you are using lead solder you really shouldn't be cranking up the temperature like that either.
i wet it in the sponge for a second or two. i fair bit of steam, the digital display still says 450 wow i think, very fast response.
i then put it on a pad and nothing happens.
Well, that is what is expected. As already said by StubbornGreek - don't put it onto a wet sponge immediately before trying to solder. There is a kind of, hmm, I don't know the english words, a kind of metal shavings - wool? - made of brass or similar, much better for cleaning, easier on the tips too.
And then - patience. It will take some time to heat up something with serious heat capacitance. Your station has 60 watts, mine only has 50 watts. Still, I can easily solder ground plane connections, actual small heat sinks that are fixed to the board by soldering thick pins to the ground plane, rather large shielding cans to ground strips, I even managed to open and solder shut again a crystal oscillator in a beefy metal can (that needed the help of a small propane torch though lest it would have taken ages... ;-).
So, I don't see why your soldering station would not work, just give it a bit more time.
