@techknight:
That's why I don't recommend it. Even with the specialized "tonsil soldering irons". Add to that the epoxy which is described correctly above (which many high end motherboards use - and is really hard to work against with tonsil type irons) and twist+turn is the best method IMHO.
100% agreement with Osgeld.
In my experience I've never ripped a trace with the twist method (remember to go slow and change directions, never rush it), while I have destroyed many traces trying to be "proper" and using irons. And I've replaced hundreds of SMD caps, maybe in the thousands, on platforms ranging from Macs to NeXTs, Amigas, IBM clones, various embedded systems, PCI/AGP video cards, and FPGA dev boards.
