Really!??Cool.... well I am more then open with my soldering techniques, so pull up a chair dude!lol
OK first step as you know, this stuff requires a fairly high tech setup..Fortunatly thanks to ebay and Hong Kong... this can actually be had... cheap...
I bought this.. I have always wanted one.

Unreal... these units made by other folks such as weller or Hakko, fetch a
HUGE Penny.Im so happy with the unit I will be buying another one, just because it is that good of a deal. Next.. smallest tip you can buy for it is a 0.1, which is what i use.It also is uses Hakko tips, also avalible on Ebay.The iron is slender pencil grip wieghs nothing and is fully temp controlled(LED Indicates temp).
You can also see the other part of this unit that makes me horny is the hotair SMC rework station. I can replace those chips entirely, messed up by noobs using this device, I have experiance removing and replacing chips similer to our famous d2 chipset seires. So you can see how kickass of a machine this really is!
Of course its all great to say how awsome it is, however one must also be able to use it effectivly.
So that being said I will not be covering SMC hotair usage, as you really need to practice HUGE before even attempting ...
Moving on, Basically what i do. I find the finest wire i can. I dont buy it just cut some insulated stranded wire from some old electronics.
Next I take a pair of non gripped needle nose and make a small leg (90 bend) Like i mean tiny. You can see the first leg on the right was actually a little big.The wire length im working with intially about 2 inchs.
Next flux wire with flux pen. next tin wire leaving a *slight amount, like i mean next to nothing at the base and just above the point of attachment..Flux again.
Flux exposed material on chip with flux pen.
Next is all the skillz man. Basically i attach the wire to the pad first; iron is set at 185 degrees.
next i bend the wire against the chip. Using a small blunt tool(dentist tool!lol) causing the wire to form into/overtop the small(shelf) part of the chip, you can see this how mine contours the chip. next...flux wire again as well the chip..This is the hardest part. Apply heat to the wire directly ontop of exposed metal for a fraction.... Its hard...... even a fraction to long, your entire leg will desolder instantly from the pad, and you have to start all over again. now... I also do this again after removal of the final excess wire off all three wires. Use SHARP(NEW) fine flushcut pliers. Then yes once again after straitening and verify the legs are perfect and not bridged in anyway. This takes me about 2 hours with PERFECT LIGHTING, 400watt MH above my desk.
I would never want to change the heat signature of any electronic chip, this is why i refuse to grind into an IC.
