infrared narrow beam heaters ?

Perhaps you could modify a hot air paint stripper to make a small nozzle?

Yeah, ive actually got a hot air soldering station for doing such things, but since it blows , it blows the solder off the PCB, so you can only really use a IR type thing... They do make 150W IR devices for SMT reworks, fear at the cost of one of those things though!

Perhaps you could make a large bit for a soldering iron from something that doesn't wet out with solder easily - perhaps stainless steel or aluminium? Use it to apply heat direct onto all the pins at once.

For such jobs I use a Weller Pyropen with a hot air nozzle. (They come with 2 sizes hot air nozzles.)

And some proper solder cream, not the wire-type solder :-)

Yeah im using the solder paste at the moment, looking to get a none-flame gas soldering iron type thing also, I cant use the paste with a blower since it blows the paste everywhere. ah well.....

Then try a pyropen. There is neither a flame nor a blow anywhere near 'blowing away the paste'. Use the 1 mm nozzle.

Have you tried turning down the air flow on that hot air station and using a board pre-heater?

any air flow messes it up, I have found that my 22W 12V lamp is the best tool, simply put past on the tracks, plog IC on top, put board ontop of the lamp for about 2 mins and leave to cool, worked first time!
